Michael Kurz commented on MYFACES-3326:
---------------------------------------

Would be interesting to know, why the data model is refreshed and the state is cleared before rendering.

> I have a h:dataTable component with an h:inputText component per row bound to a list. Now I want to add a new row with a h:commandLink outside the table via ajax. This link is immediate to avoid validation on the input components.
> The problem is, that when I set the command link immediate, data the user entered into the input components vanishes (render and execute in f:ajax are set to the table). I did some investigations and saw that UIData.encodeBegin() resets the state (and submitted values!) before rendering. IMO, the submitted values must be preserved if phases 3 to 5 are skipped.
> I first thought that setting _isValidChilds to false in processDecodes if renderResponse() is called might work. But as the link is outside and after the table renderResponse() is not called yet at that point. I wonder what the correct way to handle this could be? Maybe remember if processValidators() was called on the table. If not, don't kill the state.
> Btw. the same applies for ui:repeat.
