ScriptRunner - Triggering one behavior scripts within a separate behavior script?

[Michael]

Hello,

Is there a way to trigger a particular behavior script (Script A) within a separate behavior script? (Script B)

[Nic Brough -Adaptavist-]

I'm afraid it is not possible - Behaviours are injected into screens, and the browsers rendering them have no way to support this.

Thanks @Nic Brough -Adaptavist-, I knew it was a long shot but I thought I should ask.

The reason I ask, is because we have 3 separate single select custom fields, 2 of which we currently have scripts within, and the 3rd we want a script to check the values of both previous fields in order to change values within that field.

For example:
"Brand" customfield (Brand1, Brand2, Brand3)

•  The "Brand" field we have a script which changes the available values within the "Team" single select based on the brand value selected.
  
  

"Request Type" customfield (New, Update Existing, Perm Change)

• The "App Request" field has a script which shows / hides fields based on the request type. 
  
  

"Team" customfield (Team1, Team2, Team3, Team 4)

Goal:
We want to have a script within the "Team" field which looks at the values within both the "Client" and "Request Type" field so that:

1) If the "Request Type" is "New" -> This script "overwrites" the previous Client script and opens up all values within the "Team" customfield.

2) If the "Request Type" is either "Update Existing", "Perm Change", the "Team" script would do nothing and leave the values alone. (IE: The field values would still be changed by the "Brand" field script.

Is there anyway this could happen?

Also @Nic Brough -Adaptavist-

I've noticed that (at least in my environment) when a user loads a screen a behavior is within, it seems to take a "second" for the behavior to run; basically making it look like there are a bunch of options before "Jira" takes all those options away and replaces them with what has been scripted within the needed behaviors.

I've tried adding a ".setHidden" to all the needed fields within the "Initializer" scripting section, but even then it still seems like the behaviors takes the same amount of time to "load".

Is there some type of option which allows us to run the behaviors before the form renders to the user?

Thanks,

Mike
