Apply parameter to a report dynamically - getting rid of Apply button

Hi Guys,

I am currently evaluating JasperReports Server pro and Jaspersoft Studio Pro.

I have created simple report with one parameter; When you select the parameter option from the combo box on the report you need to press apply button to see the data update.

Question is: Is there a way to apply parameters dynamically, missing the 'apply' button step?

So you have your combo-box with list of options, you select/click on one option and your report updates then, not after you click apply button. It just seems like totally unnecessary step when you have simple report with simple querries.

Thanks to anyone who can help!!!
