I have a view that contains 4 separate backing beans, three of them being Lists of
entities that are displayed using an <h:datatable> tag. My problem is that if I get
a conversion or validation error on the form, the fields within the datatables are
reverted to their values from when the form was originally rendered, before the user
potentially changed values. The only case where they are not reverted is if the
conversion/validation error occurs on a field within a datatable. In such case, all
entries rendered within that datatable retain the value that the user changed them to (a
partial victory!). To extend that thought, if I purposefully enter one invalid entry
within each datatable, the entire form is redisplayed with the exact values that I
entered.
Anyone have an idea why this is happening and what I can do to resolve it such that, if
any conversion/validation error on any field, the entire form, including all datatables,
is redisplayed with the data as I entered it?
FYI, I had a theroy that Seam or JSF had difficulty handling a form with multiple backing
beans. So, one thing I tried was to create a POJO to act as a backing bean, put all 4 of
the previous backing beans within it, define a factory method to load the new backing
bean, then change the view to reference the new, consilidated backing bean.
Unfortunately, same result...
Thanks for any help you can provide!
Here's the code, after I combined the 4 backing beans...
