Initialize bpel variable

[Niggy]

How do I initialize a variable in the bpel mapper?

Use an Assing operation. You can put a literal value in the first argument and
connect the second to your variable.

Thanks Wouter.  What would I do in a while loop?

That depends on what you'd want to do :-) Can you be more specific?

I want to iterate through an invoked and received complex type using a counter in order to copy all the element values to my wsdl's complex type.  I guess I need to initialize a counter which should always be less than the count of my complex types and then create an assign to map all the elements if all that makes sense?

You can use the ForEach activity for that. You can find that in the Structured
Activities palette. If you'd like to keep track of a counter you might initiate
it to 0 before the ForEach activity and then increase the value inside the
ForEach activity with another Assign activity.

I have it working almost.  The For Each activity is iterating through an assign which copies the complex type and its elements.  The trouble is that it is overwriting the data, so I only see the second item in a set of two.  Any ideas?

Could it be because you are not using an index to access your repeating elements? Repeating elements are like arrays, and you need to use predicate expression to get or set values.
Perhaps this blog entry will help you do create predicate expression.

OK.  If I set the predicate to 1, I get the first element and so on.  That works.  If I initialize a counter before the foreach and increment it in an assign during the foreach and use this counter+1 as the predicate - since the values are accessed from 1 upwards - I get a selectionFailure.

Where do you get the selection failure? What does the log say? What does your BPEL look like?

Did you use the BPEL debugger? Try using that to debug your project.

Its ok - I was iterating through the foreach loop too many times.  Everything's working.  Thanks for sticking with me on this.
