-------------------------------------------------------------
Confirmed. The problem is that there are nested Form XObjects which are being
handled incorrectly. The problem code is this line from {{pagedrawer/Invoke}}:
{code}
// find some optional resources, instead of using the current resources
PDResources pdResources = form.getResources();
{code}
The call to {{form.getResources()}} returns the resources for the form only,
and not any parent resources. This seems to be the wrong thing to do.
Does anybody have any insight into why {{form.getResources()}} behaves as it
does? Will a fix break something else?
