David,
Do the steps and components already exist, or do you need to create
them on the fly? It would also be helpful for you to post the
exception - that might help us figure out what's going on.
Like I said before, it should just work - you shouldn't have to write
any code at all to move all the data back into the objects.

There are 1+ RoutingSteps for every Routing and 1+ RSComponents for
every RoutingStep.
I can get the attributes of aRouting to update without problem, but
I don't know exactly how I'm supposed to write the code to step
through the 1+ RoutingSteps and update it's attributes (stepNumber,
stepName, instructions) and the same for the RSComponent attributes.
The page builds exactly how I want it to, all of the WOTextFields
and WOPopUpButtons populate correctly, but when I click the submit
and call the method that would write my changes into the
EditingContext, I get a nullPointerException when it reaches the
aRoutingStep.setStepNumber(aRoutingStep.stepNumber()) call.
When updating several Objects of one Entity, do I have to iterate
through the array of Objects, or what? This is the part I think I'm
just not getting. Maybe. I just don't know and I can't find any
documented examples of updating multiple Objects of one Entity with
one WOForm.
Thanks for your patience and help!

Where are the repetitions? What are the bindings inside a

Hi all,
I am revising my question some.
Some review first. Here's my form structure:
<form>
Routing
-RoutingStep 1 of Routing
--RSComponent 1 of RoutingStep 1
--RSComponent 2 of RoutingStep 1
--RSComponent 3 of RoutingStep 1
-RoutingStep 2 of Routing
--RSComponent 1 of RoutingStep 2
--RSComponent 2 of RoutingStep 2
--RSComponent 3 of RoutingStep 2
-RoutingStep Etc, etc, etc.
</form>
I have no problem accepting and updating the "Routing" entity,
but I'm having problems getting the multiple related RoutingStep
and RSComponent entities to update. Can someone give me a general
outline of how the method for writing the changes into the
EditingContext should be formatted? I can't find any
documentation of this anywhere. This method is bound to the
submit button "action" binding.
Thanks!
Dave
