Hello forum,

I am trying to use a pager with listShuttle. The reason for this is
that my sourceValue (list) can be quite large, and I want the operator to be
able to search, sort and page through the values to find what he
wants, rather than have a huge list in the "sourceValue" column.

I have implemented this and everthing works perfectly, except for the validation error
(below). This error is always against the first item showing in my sourceValue, and
happens when I try to page forward or backward. The page-forward works properly, and
the first item on the new "page" will cause the next validation error if you page
the sourcValue again.

Other members of the list (item 2..n) do not show the validation
errors, just the first one.

In the implementation, when the user presses a page-forward button, I replace the
"sourceValue" list with the values of the next page.

The error does not have any effect on the operation, except the
error log that is emitted.

I created a validator for these objects & declared it in faces-config.xml, but I can
see from debug printlns that the validator is never called.

I thought that my a4j:commandLink (pager button) was submitting the sourcValue so I put an
ajaxSinge=true on it to see if I could stop the error, but this also did not make any difference.


I know that this usage of the shuttle in this way might be a bit unconventional... but, if anyone has any suggestion on what is wrong, please let me
know.


The errors look like this:
