Hi, Srinivas,
I think the problem you're having is due to the fact that during the
Request-Response cycle, you're changing the component template
between the appendToResponse that generates the page, and the final
invokeAction that uses that generated page.
For more information about this problem, see:

Hi Group,
I have a component , which have couple of WODynamic emlements, the
page looks like as shown below:
Form
Popup Button Submit Button
Table
Repitition
TR
TD
WO Text wrapped in a WO Conditional
End of TD
End Of TR
End Of Table
End Of Form
The list binding of Popup in the top has following values ("Text &
Graphic", "Only Graphic" and "Only Text").
1) Now when the user selects "Text & Graphic" in the drop down and
submits form using the submit button beside the dropdown as shown
above, the WO Conditional gets satisfied and WO Text in that is
shown to the user.
2) The value binding of the WO Text is binded using the object
which is binded to the "item" binding of WO Repitition (lets say if
I have binded students list to "list" binding of repitition and
student variable to "item" binding then the "value" binding for WO
Text will be " student.description").
Now since the WO Conditional got satisfied the WO Text element is
shown but the data is not displayed with in the WO Text even though
there is some data present. whats happening is, when I submit the
form since the WO COnditional is satisfied the WO Text is displayed
and the set method of Student.description (description is an
attribute of Student entity) is called with a null value and the
actual value present in the description is overridden by the null
value.
I didn't write any code to change the value of the desciption field
of Student.
The above problem is not seen if I dont have a WO COnditional at
all , that is if I simply have a WO Text in the repitition then
value is displayed appropriately.
Could anyone help me out finding out the problem and probable
solution for the above scenario.
Thanks & Regards,
Srinivas
