MyFaces DataTable and preserveDataModel

[Mik Lernout <ml...@maketechnologies.com>]

Hi all,

 

I am having some issues when using a MyFaces DataTable that has the
preserveDataModel attribute set to true. When I put an instance of it in
a panelTab that sits, quite logically, in a panelTabbedPane.The
following series of actions fail: click a tab that does not containg the
data table and and after that open the tab with the data table: this
gives me the null pointeryuo can find at the bottom of this mail. I am
nearly sure it is related to the preserved DataModel being constructed
in the view-phase, but not being rendered, filling the session with a
malformed preserved DataModel.

 

Could someone confirm this?

 

Mik
