previous parameter value

JDyne

I am trying to hide a parameter based on another parameter selection. If I add the following line in getDefaultValueList event, it hides the parameter

reportContext.getDesignHandle().findParameter('param2').setHidden(true);

what I am not able get is the previous parameter selection. i.e. I am not able to do the following:

if (params["param1"] == "Something") {
reportContext.getDesignHandle().findParameter('param2').setHidden(true);
} else {
reportContext.getDesignHandle().findParameter('param2').setHidden(false);
}

params["param1"] always returns the default value set for param1, it does not provide the selected value. Can someone please help me accomplish this?

Thanks

I don't think this is possible in the standard BIRT parameter page.

There is no event that is fired when you enter/change a parameter. So even though you may have changed the parameter, BIRT still sees the parameter as the original value. It doesn't recognize the changed parameter until you actually exit the parameter page.

I'm thinking you would need to create a custom parameter page to do this.
