BIRT: validate parameter and display error

nevest

HI,
I've just defined a method to validate date parameter in my example.rptdesign
here my method:


if (params["data_from"].value.getYear() > params["data_to"].value.getYear() )
{
false;
}
else{
if (params["data_from"].value.getYear() < params["data_to"].value.getYear() )
{
true;
}
else
{
if(params["data_from"].value.getYear() == params["data_to"].value.getYear())
{
if(params["data_from"].value.getMonth() > params["data_to"].value.getMonth())
{
false;
}
else
{
true;
}
}
}
}



now... HOW can I display a message instead of the message of exception.
can I capture this exception??

I use birt 2.3.0 RCP Designer

help me please!!

You have probably already solved your issues, but for anyone else with a similar question, you can create your own parameter page and handle the parameters however you'd like.<br />
