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.

		try
		{
			getValue( value );
		}
		catch ( BirtException e )
		{
			return ERROR_MSG_MISMATCH_DATA_TYPE;
		}
		return null;
	}
	private boolean isEqual( String value1, String value2 )
	{
		Object v1 = null;
		Object v2 = null;
		try
		{
			v1 = getValue( value1 );
			v2 = getValue( value2 );
		}
		catch ( BirtException e )
		{
		}
		if ( v1 == null )
		{
			return v2 == null;
		}
		if ( v1 instanceof Double && v2 instanceof Double )
		{
			return ( (Double) v1 ).compareTo( (Double) v2 ) == 0;
