2 months ago Please check implementations of openStartProcessForm and openTaskProcessForm of the io.jmix.bpmflowui.processform.ProcessFormViews interface, and their usage in StartProcessView and InputDialogTaskProcessForm.
When I move from 2.2.3 to 2.3, I get problems with opening, probably due to the breaking changes "Navigation Requires Origin View" and "Navigation to BPM Process Forms" and I think this is related because the process forms are "navigate" and "this tab".
Kind regards, Mladen

Environment
Jmix version: 2.3.0
Bug Description
When Jmix view process form has parameters, for example params = { @Param(name = "variableName"), @Param(name = "entityPickerCaption") }
and a form is opened in 'Navigate' mode (This tab), values of the parameters are equal NULL
Steps To Reproduce
Create a process:
Set Task 1 properties:
Create Jmix view form with parameters (see attached file)
Set Task 2 properties -- the same like Task 1, but Open mode = This tab:
Deploy the process
Current Behavior
Start the process
Open Task 1 -- params values are OK:
Open Task 2 params are nulls:
When using params in code, it will cause NPE.
Expected Behavior
Parameters are passed from the form properties, not nulls.
QA notes
The problem also exists for the start form and a fix has been done for this case as well.
