How to resolve #{row} of af:table in custom tag class?

Question

Hi all,
My customer creates custom converter tag with some attributes. When they use it outside af:table, it works as expected.
However when they use it in af:table and set "#{row.value}" into the tag's attribute, it doesn't work because it can't resolve #{row} EL expression.
The method they wrote is like below.
private Object getExpressionValue(ValueExpression expression) {
if (expression == null) {
return null;
final ELContext elContext =
FacesContext.getCurrentInstance().getELContext();
return expression.getValue(elContext);
Does anyone know the way to do resolve #{row} expresison in custom tag class?
If you share sample codes, it will be much appreciated.

Hi,
the row variable is a temporary variables, which means that #{row} may work when the table renders but not when users edit fields in a table and then submit the change. You don't really mention what doesn't work for your customer (and wouldn't it be better your customer could post here on OTN to avoid you becoming a dispatcher?) . An expression #{row.value} for example doesn't exist unless your customer uses a POJO model that has a property "value" in which case the entity has a setValue/getValue.
