Hidden component
I'm trying to use the Hidden component instead of using a persistent
property. I can see that the object gets written to the html source, but
when I reference the object in the LinkSubmit's listener, the object is
null. Even when I try a simple String. I can see that the page property has
the proper value when the page first renders, but I can not see why the
value is ending up null in the listener.
Any thoughts?
thanks,
Jamie

The listener is Java, Groovy, Jython or what?
We had this issue with Groovy listeners not resolving correctly
expressiones like:
page.beans.someBean
that had to be replaced with
page.getBean("someBean")
for Groovy to resolve correctly the bean reference, otherwise it created
a brand new (and null) someBean "property" for "beans".
Hope this help...

I haven't tried this yet, but I am sure that's the problem. The link submits
are before the hidden fields. Glad I asked. I wouldn't have thought of that
in a million.
Thanks,
Jamie

Where are the Hidden and LinkSubmit components, relative to each other, within the Form? If the
LinkSubmit precedes the Hidden, then the Hidden will not have had a chance to restore the property
before the LinkSubmit's listener is invoked.
