Hello,

is it possible to add custom categories into the Expression Builder Dialog?

Thanks!

Jeason,

thank you for your hint! Unfortunately the example seems not to work when
using the jslib Path feature. (BIRT 2.5)
Currently I've set the location to a 'js' folder located right at the
plugins root.
Inside this folder I currently have one script file called foo.js:
var preloadstring = "this string was preloaded";
function getPL(){
return preloadstring;
}

When opening the Expression Builder Dialog I see my category, but no
function from within the js file(s).

Are there any regulations concerning js files that I've to follow?
Thanks!

I've checked the "my.expression.functions" plugin, and the getPL()
function from preloadjsfile.js is not listed here as well using BIRT 2.5 :(
Bug or feature?

Jan,

Thanks for posting this. This appears to be a bug in the
populateResources method of FunctionProviderImpl.java If your location
is jslib the url that gets created with the following:

while ( files.hasMoreElements( ) )
{
String element = files.nextElement( ).toString( );
if ( element.toLowerCase( ).endsWith( suffix ) )
{
try
{
libs.add( new URL( url, element ) );
}
catch ( MalformedURLException e1 )
{
}
}
}

Produces a url /jslib/jslib/javascriptfile.js

As a work around take the jslib directory and nest a copy inside the
same jslib dir.

Can you log a bug for this?
