So I'm upgrading to Primefaces 11.0.0. I see that for static columns the regex have changed to only accept the case sortBy="#{car.name}". For dynamic columns its e.g #{car[column.property]}. So its much more strict. I have previosly used sortBy="#{treetab.row.cellMap[column.id]}". So this is not working as the regex does not handle it. How should the sortBy expression be?
