Keyword _nf Issues

[jbk68]

Lately I've noticed that the keyword "_nf " is not working at all times as expected. I have 4 table columns that have successfully hidden from showing up when a users presses Knack's "add filter" button. But the last couple days, I've noticed that at times, these 4 hidden names will appear in filter drop down list. If a user changes pages and/or hits refresh, occasionally these names will hide as expected but not always. Then there are times if the names are hidden in the filtered list and the user refreshes page or changes pages and returns, the 4 names are present again. ???

Just a fyi, I've tried using both the field name, which is what had been working, and the field id at the view level with same results listed above. I then tried the keyword at the field level, same result.

Any and all help would be appreciated... JON

Hi Jon,

I've just tested my _nfs and am seeing the same issue. I've tried _nf in both field and view and encountered the same issue. It appears random and no errors appear in console.

We're using Ktl ver 0.22.14, I also tried it in KTL-Dev, with same results.

In our case we're hidding 3 fields from filters, however, it's always just the same 1 field that appears. The issue is intermittent.

Hey Amanda, thanks for looking at that for me.

Don't take this the wrong way but glad to see others are having this issue also and not an isolated issue with me. :)

Hopefully Norm has a fix for it soon... JON

Hi guys,

I think I know what's happening. I apply the kw a bit too early. As a consequence, some entries are populated afterwards.
I'll see how I can fix this.

Next time, create an issue please.

Hi guys,

No matter what I try (_nf in field, view or both), I can never reproduce the bug here.
Is it possible to create a page for me to access and debug in your app?

Norm

[jbk68]

Hey Norm, I just added the keyword to the debug page I set up for you a couple weeks ago and the keyword _nf works just fine in that page. I tried it in the view mode using the actual field id. Not sure why both me and Amanda are having similar issues in our real live apps. It weird, when you first open the app and got to add filter the field you want to not show in the list are hidden but when you refresh page or change to another page then back, hit add filter, hidden fields are now shown in drop down list.

Just a fyi, the debug page I setup for you is part of the same app I'm having issue with just setup up a separate page/table named "debug"

Thanks... JON

@jbk68,

I'm not sure I understand, when you say:

"I just added the keyword to the debug page I set up for you a couple weeks ago and the keyword _nf works just fine in that page."

Are you saying that I won't be able to reproduce the bug there?

I'd like to test that page, but will I see the bug?

Norm

[jbk68]

No you will not see the bug in the "debug page" I set up for you. If you remember, the debug page was very simple and only had 4 fields visible on the table. I added the keyword _nf to the debug page with the intention of hiding 2 of the fields (ie _nf=field_1, field_2) and both the fields were successfully hidden for the filter drop down. If I removed the keyword, all fields on the table were shown in the drop down of the filter box. If I went and just hid one, that one was hidden. I tried refreshing the page several times and could NOT reproduce the issues in my real life app that both me and Amanda are experiencing.

Ok then. I'll try something else.
But it's tough when you're shooting in the dark!

And BTW, I sent you an email. I can't log in your page anymore.

[cortexrd]

@amandajane-mo ,

Any chance I can log in your app to see the bug?

Norm

[jbk68]

Norm, trying logging into that debug page now using same credentials. Just a fyi, I

[cortexrd]

...missed a few words?!

[cortexrd]

Did someone close this issue?!

[jbk68]

I just replied to your email.

[cortexrd]

Got it, I'm in now. I see _nf working as expected, hiding fields 2 and 3.

I've released a dev version. Can you test it to see if it makes a difference?

Norm

[cortexrd]

@jbk68,

As expected, I can't reproduce the issue in your app.

Waiting to see what the dev version does for your buggy app...

@amandajane-mo : if you have the chance to test it also, would be great.

ND

[jbk68]

dev mode still shows hidden fields in filter. How do I get out of dev mode ?

[cortexrd]

I've added a few logs. Let me know what you see compared to mine - but only when the bug occurs.

This is the normal expected behavior: I have 4 fields in the _nf keyword.

So here's what I see in the console output:

1. _nf click processed should always be seen, wherever you click in the page.
2. If you click on a filter element (Add filters button of in the popup to add new filters), you should see this log: filter element found
3. Followed by 4 waiting for: ...
4. Followed by 4 Removing:...

The rest is a sort of parasitic event and not important.

Try the dev mode and let me know what is different on your side - when the bug happens.
You can copy/paste your logs here if you want or take screens grabs.

BTW, I've discovered the coolest app for this: ShareX (https://getsharex.com/). It allows editing the capture right-away, add text, arrows, boxes, etc.

@cortexrd

@jbk68 do you have more than 1 grid (of the same object) on the page you see the error?

We've started to spot a pattern:

1. 2 grids of same object on page, both with same fields to be filtered
2. If we have description DF on both views _nf works as expected
3. When we remove description DF from 1 of the views, it will fail, depending on the order the views are loaded, if the view containing description is loaded first it will fail, the 2nd view (which now doesn't have description in it) appears to determine the filters on the first view.

We're still testing this, but does appear to be a pattern, we tried it with a different field and had the same results.

Amanda

[jbk68]

Amanda, on the page have issues, I currently have 2 views but both have a different data source. One view (upper) is having the issues of showing the (3) fields I wish to hide and the other view (lower) is working fine and is hiding (6) fields successfully. Never had an issue with lower view.

But after receiving your inquiry I tried the following and saw the (3) fields successfully be hidden regardless of how many times I refreshed page or move between pages.

Here's what I did: I added to the 2nd (lower) view/grid the (3) fields (connected) that I want to hide in the upper view. I then at the "field" level, added the KW _nf to the (3) fields having issues. After doing this, the upper and lower view now BOTH hide the fields in the filtered list. If I put the KW _nf at the view level, the upper view went back to having issues. I then add the KW _hc to hide the (3) fields from being viewed on the lower view/grid.

Until you guys get a fix, this is working for me... JON

[amandajane-mo]

Mmmm, it's a weird one. Hopefully Norm will be able to track the issue down with our findings.

[jbk68]

I have faith he will. Just a fyi, I had another field from "top view" that I wanted to hid in the filtered list, once I added it the the lower view, and added the kw _nf to field view 's description, it now successfully doesn't appear in either view.

I might add a 3rd view/grid to this page, just to add and then hid these fields, then simply hid the view. ???

@cortexrd

Screenshots

view_4917 - has description field_6607 on it
view_4961 - doesn't have description

In above screenshot description is NOT hidden from filters in view 4917

In this case view 4961 loads first and description IS hidden from filters in view 4917

Hope this brings some enlightenment

Amanda

[cortexrd]

Ok guy, thanks for your new input.
I can now reproduce the bug at will.

Here's my setup:

A page with only two grids.

Both have Phone and Email columns.

Grid 1 has _nf=Phone, Email
Grid 2 has _nf=Phone

I can make Grid 1 fail every time by doing this sequence:

1. refreshing the page
2. refreshing the Grid 2 manually with the Click+Click Hold trick

When open the Filters for Grid 1, Phone will be there, though it shouldn't.

Now, let's see how I can fix this...
Norm

[amandajane-mo]

Thanks Norm and Good luck

[jbk68]

Thank you sir... JON

[cortexrd]

Ok, I think I'v got it cornered... again !!!

It was much harder than I thought.

Give it a try please, dev mode.

Norm

[CSWinnall]

The screen shots I have posted are all the views that have the afore mentioned setup

[cortexrd]

It seems that view_4916 is problematic.
Can you try this: Knack.views['view_4916'].model.view.filter_fields
That is just another grid like all others?

[CSWinnall]

That is the menu view

[CSWinnall]

[cortexrd]

Ahhhh! Now I get it.

[jbk68]

Hey Norm, I can confirm the keyword _nf is working in dev mode as expected both by selecting the field to hid at field and view levels.

Much appreciated... JON

[cortexrd]

@CSWinnall

Can you reload dev and test please

Norm

[CSWinnall]

No Error or console.logs but on switching pages no field are filtered

[cortexrd]

No it's worse now...

[CSWinnall]

We have given you access to this page:
audits/upcoming-audits/
After the #

[cortexrd]

Thanks, I will try that later.
For now, I found another intermittent use case with my setup. I have to find a solution here before I test your bug.

ND

[jbk68]

Just spent the last 15 minutes in dev mode trying different things like refreshing page and switching back and forth thru pages and any and all items that I filter, stay filtered in dev mode. I even removed the _nf keyword and the fields I want to hide and when I remove the keyword, fields are displayed, put them back in either on the view or field level and filtering works just fine.

Once I get out of dev mode, filtering issues returns within a few page refreshes. Dev mode, no issues...

[cortexrd]

Ok guys, one more time!

I had to rewrite a big chunk of code with a different approach again.

Please try dev.

Norm

[amandajane-mo]

Hi Norm,

Sorry, same issue. In our tests it never fails after a refresh but always fails after a move between pages.

Amanda

[jbk68]

Still works just fine in dev mode on my end regardless of if I refresh page or move between pages. I even added a couple extra fields to hide and they were also filtered from being seen in the list.

Not sure what you've done since I initially started this post/issue a few days ago, but ALL my apps are 100% working now, at least in dev mode.

Thank you... JON

[cortexrd]

@CSWinnall

I am on your page now.
I click on all menu items, but can't see your issue.

Shall we have a Teams meeting?

Norm

[CSWinnall]

Give us 20 mins?

[cortexrd]

Ok, I see the _nf issue. I was looking for the console error, but it's not there anymore.

[CSWinnall]

Yes the error went away.
When changing pages all fields show

[cortexrd]

Try dev again please?
Norm

[amandajane-mo]

We've both tested numerous times and can't get the issue to occur.

Looks like you're on to something

[cortexrd]

I will close this and do a release.
If you see something else, reopen.

Thanks to all for your perseverance and patience!

Norm

Thanks Norm... JON
