the problem is a little bit tricky ;)
If you use preserveDataModel="true" the value of your datamodel is not
requested until in the renderphase and will not be used for iteration
and setting rowindex. This is the reason why you don´t get a valid
value for your rowindex and rowdata in process application phase. I
suggest you to change your jsp/bean code into one of the following
way:
- implement your action method into a WfAssignment wrapper class and
use instances of it in your datamodel. Change your jsp code to call
this action method in the wrapped class.
- don´t use preserveDataModel and make sure that your getter method of
the datamodel returns a non null or empty value during the decode
phase.
- provide a setter method for your datamodel. This method is being
called in the update model phase to set the preserved datamodel. The
preserved datamodel will only contain the values for the rendered
page.
