REP-0546 when displaying parameter form

Question

Hi,
here is my issue:
when i run the report from forms with paramform=no the report works fine and produces valid output.
However when parameter paramform=yes the parameter form window comes up with error:
REP-0546: The parameter value is invalid
I am puzzled.
Any suggestions?

Hello,
Reports are 11g, there are no before or after trigger. However there is validation trigger on the parameter. I am running the report from Oracle Forms 11g
Here is a code snippet:
