restoreState problem in primefaces DataTable with MyFaces
Hi,
I have a problem with primefaces dataTable in combination with MyFaces.
The DataTable restoreState method reads from state Object with index 4:
Object[] savedState = (Object[]) ((Object[]) state)[4];
This causes an IndexOutOfBoundException.
I've seen that Mojarra saves the state of StateHelper at index 4 and so
it works. But the MyFaces state object has a maximum index of 3.
Does the spec define an order for state saving. e.g. stateHelper at
index 4 in UIComponentBase? Or is it a PrimeFaces bug to read from state
of the super class directly?
Thx, regards
Marcus

Hi Marcus,
The spec does not say anything about the ordering of values in the state, so
this is by all means a PrimeFaces bug. If PrimeFaces wants to use the state
of the super class, it has to save and restore this state too, otherwise it
accesses "illegal" data.
Regards,
Jakob
