BPM SR2 with lastest Hotfix...

1. Create new process

2. Add a second form ("form2")

3. Add this second form to FirstStage

4. Receive message box stating:

"Object reference not set to an instance of an object"

5. Same message received when removing "form1" from "firststage" as well.

Here's part of the stack trace:

System.NullReferenceException: Object reference not set to an instance of an object.

Any ideas?

Ouch!

Good job we have stuck with 9.0.2 without hotfixes!

Anyone else seen this?

It does seem to be the case with 9.0.3.3 (which I am using to tie in with a development by someone called called Jason... could it be....)

Saving the project, ignoring the warnings, and then closing and re-opening it seems to leave it with the correct form at the stage, no problems so far anyway, but it's a right royal pita
