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.

	private void clearNewParameter( )
	{
		newParameter = null;
		givenName = false;
	}
	protected int getTableIndex( Object element )
	{
		Object[] input = ( (IStructuredContentProvider) valueTable.getContentProvider( ) ).getElements( valueTable.getInput( ) );
		int index = 0;
		if ( element != newParameter )
		{
			for ( int i = 0; i < input.length; i++ )
			{
				if ( element == input[i] )
				{
					index = i;
					break;
				}
			}
		}
		return index;
