Hi,
I have run into a problem that, judging by the posts in the archive,
numerous others have run into:
java.lang.NullPointerException
at
org.apache.struts.action.DynaActionForm.getDynaProperty(DynaActionForm.java:
551)
at org.apache.struts.action.DynaActionForm.set(DynaActionForm.java:365)
I read all of the previous messages and have tried the suggestions listed
there but I still haven't got it
to work. I would greatly appreciate some help with this.
