Dynamically change the default value of a parameter at runtime?

chorton

I'm looking for a way to change the default value of a parameter at runtime.
When I run a report I need the parameter to default to the current year and month (exa. 201004) while also giving me the option to change it before clicking OK on the parameter screen.

I have a script worked out to get the appropriate year and month and apply it as the value when the report is ran. The problem is that I can't get my value to display in the parameter's text box.
With my script running in the 'initialize' method the report works like this when the 'Preview' tab is clicked.
1. User gets prompted for a parameter which is blank
2. User enters a value and clicks ok.
3. The value entered by the user gets over-written with the value created by my script.

I need a way to place my value in the blank text box so that the user can change it if they need to.

I hope that makes sense.

Hi chorton,

What version of BIRT are you using? BIRT 2.5 has an option to use javascript for the default value of a parameter. This would be the easiest way to solve your issue.
