Exception Parameter

hi,

I have a problem: my parameters are dates, a date when step
wrong, raise an exception. I need to catch this exception and not let
the fabric of BIRT exception appears to the user.

how is it possible?
I tried to create a script to validate, but it's nowhere to validate, as triggers exception.

thanks

If you need to do some validation on date parameters, you could build your own JSP page to collect the paremeters and run whatever kind of JavaScript you need to do.

In java, you could simply execute the validateParameters method on the run or run and render task, as shown below, to check if your parameters are correct: 
<pre class='_prettyXprint _lang-auto _linenums:0'>
IRunAndRenderTask rrTask = reportEngine.createRunAndRenderTask(reportDesign);

//set render options omitted

rrTask.setParameterValues(parameters);
if (!rrTask.validateParameters()){
// some parameter is invalid, you might be able to use rrTask.getStatus(), not sure
} else {
rrTask.run();
}
</pre>
 
But as Virgil suggested, you really should have parameter validation built into your jsp though ;-) 
 
I hope this helps,
