Linked inputs

[jsuutari]

Hello everyone,

I've struggling with following concept: I've got a custom activity, that has two inputs. The first input is drop-down list that defines what kind of object the activity is requiring (the object is sent to external service). The second input is javascript editor, which is used to construct the object. The problem is that there is no way to provide good instructions for the end user on expected object. What I would like to do is, that once the first input is changed, it would provide an object model as a default value for the second input. Is this that something that could be done easily?

I decided to take the hard way and build a custom component.
I hava hree custom activities: trigger, fetch data and output. The trigger is a simple http trigger. It has autocomplete input which is populated by querying templates from "my" system. If the template provides an object, the activity adds hidden editor and creates javascript object stub and places the object into models -object. This way I have the model available and intellisense works nicely with the editor (Of course this is not the ideal way to this, but hey, it works):

The Fetch data activity works, pretty much the same way as the trigger. It is simply used to query states from "my" system. The output also uses the template system, but it has editor to build required the json object:
