Removing the 'Null' Text in ComboBox or ListBox Parameters

In BIRT 2.3.1, it is possible to modify or hide the 'Null' Text value that is generated
when you create a ComboBox or ListBox Parameter.

*Update to this Post* The syntax highlighter is not working properly.
The XML tag brackets have been replaced with { }

Go to the BIRT WebViewer JSP page in
\webcontent\birt\pages\parameter .

Find ComboBoxParameterFragment.jsp in the viewer and edit the JSP to remove the space and the Null Text Value (i.e. IBirtConstants.NULL_VALUE)

if ( !parameterBean.isRequired( ) )
{
if( allowMultiValue )
{
if( DataUtil.contain( values, null, true ) )
{
%>

{option title="">" SELECTED VALUE=""}{/option}

{option title="">" VALUE=""}{/option}

{option title="">" VALUE="" ??% : ?SELECTED? )? null paramValue="=" {/option}
