i'm trying to use jsf and jdo and i have wrote a
small application when i can insert,delete,modify a dataTable.
I use also a button that clear the form and
leave only one row so i can use it for search .
The button have immediate set to true because i
don't want syntatic control on the action.
I obtain only one row after the action but the
fields contains the value of the previous page.
I have wrote a log in the render fase and the value
of the model seems correct.
I think that the rendering phase get the value
submitted and not the value of the model.
I get the last nigth build because i supposed that
the problem was tied to the issue 187 but
the problem continue.
This is my code :
