Hi John,

After a long time this is JP again.

I have a problem which looks simple to code in PDL. However practical implementation is giving me trouble.

First I shall document the problem:

STEP1: Designer submits the design for review.

STEP2: Reviewer1 reviews has two options:

2A: if design needs inprovement he sends it back to Designer.

STEP1.

2B : If satisfied with design he sends it to Reviewer2.

STEP3:Reviewer has three options:

3A:If needs clearification on design sends it back to Reviewer1.

STEP2.

3B: If unsatisfied with the design he sends it back to Designer.with
a read only copy to Reviewer1

STEP1

3C: approves the design

My problem is that I want to go back to Step1 or Step 2 then the workflow is behaving differently.

Here writting flows is something similar to write code in Java and C. But in workflow I am not able to visualize how things are happening.

While I am using subprocesses to revert back its not behaving as 1st step behaved.

Practically , once Rev2 sends back to Designer and/or Reviewer1 we should proceed from that point.

Do I need to write different subprocesses for such cases?

I think I have confused you enough :)

I have attched the code I am using it may help you to understand what I am saying.

Thanks & Regards

JP

I like "instance".

It's perfect like that.

No, the _expression_-map almost never changes. No editor for it.

Fine.
