Bug 177439 Need an easy way to determine default value for a dynamic parameter
Currently, I have to bring up the data set editor, preview the results in the data set and make a mental note of the value to use for a report parameter that depends on a data set. It would be nice to have a drop down on the default value field, such as <Select value> which when selected queries the data set and presents me with a list to select from.

clearDefaultValueChooser( isRequired.getSelection( ) );
		}
		else if ( !type.equals( DesignChoiceConstants.PARAM_TYPE_BOOLEAN ) )
		{
			clearDefaultValueText( );
			clearDefaultValueChooserSelections( );
		}
		initFormatField( );
		if ( isStatic( ) )
		{
			makeUniqueAndValid( );
			refreshValueTable( );
		}
		else
		{
			refreshColumns( true );
		}
		updateMessageLine( );
	}

	{
		String[] choices;

			if ( DesignChoiceConstants.PARAM_TYPE_BOOLEAN.equals( type ) )
			{
				choices = new String[3];
