Displaying selected parameters in the body of a report

nelsont

I have a report where a users needs to select one or more values from a list to run the report against. I would like to display the values that the user selected in the actual report.

I figured out how to display a parameter when there is only a single value that can be entered,
but I can't figure out how to do it with a list of parameters.

I have been searching and it looks like I need to write a script in the OnFetch of the dataset that builds the list of values that the users choose from, but I am clueless when it comes to Java. Any help would be appreciated.

Hi,<br />
<br />
You may have seen this example (<a class='bbc_url' href='http://www.birt-exchange.org/org/devshare/designing-birt-reports/1305-display-multiselect-parameter-display-text-in-report/'>example</a>) posted by mwilliams. I'd recommend downloading & using it for reference - I think its what you're looking to do.<br />
<br />
One way to access the correct event (initialize, onFetch, etc) of a report item where you can add JavaScript is to select the report item in the Outline view (Window-->Show View-->Outline) and then select the Script Tab. <br />
<br />
Select the filename.rptdesign (whatever your report is named) in Outline and then select the Script tab. Then add <br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>selectedParams = params["NewParameter"].value.join(",");</pre> <br />
Make sure 'NewParameter' is the name of your parameter and that you're in the 'initialize' script event. After that you can reference selectedParams in a Dynamic Text report item (as an example) using the Expression Builder.<br />
<br />
Hope that helps,<br />
