Sort foundset using related tables' columns

[sirikumara]

Hi All,

I tried to sort foundset by related tables' columns. But It didn't work.My code is like following sample. Please give me the correct way of sorting foundset with related tables' columns.

foundset.sort('column1 asc,column2 asc,relation_name1.column_name1 asc,relation_name2.column_name2 asc')

Best Regards
