> Facelets just translates it to #{}

Okay, so not the reason for the problem.

> The exception is pretty clear: 
Sure, it's pretty clear, but wrong!

>You are trying to access entities.Finding.getFindings() which apparently does not exist.

No! I'm trying to access entities.Sample.getFindings(), because binding is mapped to #{row[value]} = samples.findings. I'm setting the table value (=source variable) before the next nested table begins!

I did not changed the Facelets version. I only switched to Trinidad 1.2.9 and than back to 1.2.8.
BTW: 1.0.14 is very old. As I wrote above (see Environment), I'm using Facelets 1.1.14.

It works for the first nested level, but not for the second. If there is a variable conflict, why does it work at the first nested level?

There is also no way to prevent reusing the same variable with the same nested elements, if I "DRY".

> I'm using a facelet component which sets a variable to the row of a tr:table (<c:set var="entity" value="#{row}" />). This variable is then used in a child table (which is also a facelet component) as source value.
> In 1.2.9 this approach does not work anymore. The entity is set to the current row of the child table and does not contain the row entity set before.
> Up to 1.2.8, all works fine. I checked the fixes for 1.2.9, but could not find a related one.
