Dynamic parameter properties [message #757572]

Is there a way to dynamically change some of the properties of a parameter?
For example, I want to be able to change the value of the property "Is required" on one of my parameters.

This is because I only want parameter B to be required if parameter A != a certain value.

More specifically, I would like to do something like this..

var paramValue = reportContext.getParameterValue("ImpactAssessmentType"); //report parameter

if (paramValue == "(Show All)") // if 'Show All' was selected
{
        ii = -1;
        // change param2's "Is required" property to false
}
else
        ii = 0;
        // leave param2's "Is required" property alone

180 views and no help? I thought this would be pretty standard. Any help please?

You can change parameters before the report is opened in the viewer, but
once it is opened the viewer will initiate the parameter dialog and it
is to late to change the values. You may be able to use a custom
parameter page using the BIRT tag libraries and some script to implement
a custom page to do this.

Hmm ok, maybe something that should be added to BIRT, seems like other people would want to do this too. Thanks.

Can you open a bugzilla request for this?
