Description Scroon CLA 2011-07-26 10:23:45 EDT 
Hello,

For a custom parameter page using BIRT tag library, the multi-value parameters are always be rendered as single-value list boxes, which does now allow user to select multiple values.

ParamDefTag class modified for using multiple values parameter in cascade
Comment 2 Jean-Michel Dupuis CLA 2014-11-17 12:57:56 EST 
Hello,

the problem origin is in the "org.eclipse.birt.report.taglib.ParamDefTag" class.

The method : "__handleListBox( )" does not treat the case of cascading parameter with multiple values.

My proposition is to replace the line : "__handleCascadingListBox( );" by this lines :
"if ( this.paramDef.isMultiValue( ) )
				__handleMultiListBox( selectionList );
			else
				__handleCommonListBox( selectionList );" in the block concerning cascading parameter.

I add an attachment with the modified class.

Have a nice day,
JM
