Riccardo Serafin commented on RF-7919:
--------------------------------------

Ok, just to let everyone know what took me some hours to figure out.

I've read the duplicated issue and the related post. Added the missing index property, and the problem was still there.

It turns out my problem was related with the fact that in values i was returning a collection of my own column description object. As such, my declaration was something like:

<rich:columns value="#{columns}" var="column" sortBy="#{row[column.property]}" sortOrder="#{column.sortOrder}">

what was failing wasn't the sort by, but the sortOrder that is not able to resolve the additional level of indirection on the column object. I had to introduce an additional Map<Object,Object> sortOrder and change the declaration to sortOrder="#{sortOrder[column]}". Now it works.

> <rich:columns value="#{columns}" var="column" sortBy="#{row[column]}" >
> where columns is a list of property names.
> We noticed that since version 3.3.1.GA it is not working anymore, but this post (http://stackoverflow.com/questions/1119321/richfaces-richcolumns-and-sorting) suggests that it is not working since 3.3.0.CR2 and we have verified that in 3.3.0.CR1 it was indeed working as expected.
