Hello,
I am trying to get the db:select tag work with embedded data. I am
getting the following exception below. Does anybody know the cause and
how to avoid this error?
It's a null ptr exception in the TableData.java caused by the doFinally()
method setting the visibleFields=null. Why does doFinally() methods set
all the fields to null? Apparently, AFTER doFinally is executed, we are
still using the Tag handler. Is doFinally's set nulls for tag re-use? If
so, why do you we not set everything to null BEFORE we start using a tag?
instead of AFTER?
I don't know anything about taglibs but i gotto fix this. Any help is
appreciated.
Regards,
Ali
