[dbforms] Problem with db:select tag - 2

[Ali Demir]

IF I comment out the variable=null code from doFinally() methods of EmbeddedData, it works fine. At least the HTML select tags are generated correctly. Should I just comment them out? What am I getting myself into?

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
