Unable to Create new Sub-Package Using Server Side Editing

[isc-jsmith]

Type: Bug

Since updating to 3.4.0 I am unable to create a new class inside a new sub-package using server side editing. For example, I have an existing class called ZJES.Test.MyClass in my namespace. When I try to create a new class called "ZJES.MyPackage.MyClass2.cls" by right clicking on the tree and selecting "New File...", I get the following error:

Unable to write file 'isfs://auxxscratch:auxx-scratch/ZJES/MyPackage.MyClass2.cls' (EntryNotFound (FileSystemError): isfs://auxxscratch:auxx-scratch/ZJES/MyPackage.MyClass2.cls)

I tested reverting to 3.2.0 and the issue does not occur and I am able to create the new class. Below is the server side folder view I tested with - there is no additional filtering configured.

If I create a "New Folder" instead to create the sub-packages, it disappears instantly as there is no class underneath it.

Hi @isc-jsmith, I tried to reproduce this but couldn't. Here's what I did:

new.class.mov

Hi @isc-bsaviano,

Ah! That's the difference - I have been typing in the new class name as I would when referencing it in ObjectScript, i.e. I would enter the class name using full stops to delimit the packages when creating a class.

demo.mov

Yeah, that worked by accident in the past but it won't anymore due to #1666. It used to be possible to open multiple copies of a document with different URIs. That confused some of our new users and led to strange behavior when using server-side source control.

Okay. Thanks. That makes sense. I probably picked up that habit early on in the life of the plugin. I'll check the docco and request a change if it's not clear.
