Hello...
Unfortunately, it wasn't that simple. I wasn't using the Script
component, because I need access to the function from the script.
However - if I do it the way Palette does it - I execute the script
*before* the components are rendered - which means I can't get to the
component names. But if I do it the Script component way, I can't get to
the script's internal symbols.
Finally - I just had to find the first component, render it, manually
process the script, then continue rendering the remaining components.
HOWEVER - it still doesn't work. Everything is as it should be. (I.e. if
I weren't using tapestry) But I am getting stale link exceptions now.
WHY??? Yes - I do have a visit object. I did not press the back button.
My script is SIMPLY setting the value of the hidden
(document.form.hidden.value = val), and then calling
document.form.submit().
Again - any help. I don't even know where to look to find out why I'm
getting the stale link. It "look like" the context/parameters/service
aren't going through.
Perhaps it's just my frustration blinding me.
