Hi,

Can I get some help, in setting null value to one of my cascading parameter.

Let me put my question clear -

I have three cascading parameters which using multi dataset to populate drop down list.The first two cascade parameters are inter dependent and I can do submit without entering / selecting any value for the third one.
I already set as not required parameter to this and need not to set with Default / NULL value for this parameter.
With these setup, when I submit to generate the report - I am getting error msg -which expecting some value for this parameter.

someone could help me out to achieve this.

I appreciated.

Thanks
Sen K

What exact error are you getting. I just tried this in the viewer and
it worked fine. The only way I know to remove the null is to change the
js parameter dialog to strip it out. This would affect all cascades
though. Look at ComboBoxParameterFragment.jsp in the viewer.
