I have a List which is displayed using jwcid="@For" I am using
volatile="true".
I also have the List 'displayed' as a jwcid="@Hidden".
When the form is submitted I reset the list to null. This causes the
jwcid="@Hidden" to throw a NullPointerException. This did not happen with
Tapestry 4.0 beta-3.
I also have a problem with XTiles if one of the parameters to be returned is
null, this throws a NullPointerException at the following line in the
XTileService.java file:
Node valueNode = doc.createTextNode(value.toString());
A null value has previously been caught and facilitated for by the framework
in each of these cases. Is this a bug? If not what is the work around?
Thanks
Paul
