Updating an inmethod grid, looking for hints
Hi,
How can I trigger an inmethod grid to do a /complete/ update of itself?
The only thing that I see is markAllDirty(). That will update the items
currently in the list, but it will /not/ get new items from the data
provider.
I researched the code for quite some time but I must have been looking
at the wrong parts as I found no hook to get this done. The most I could
do was call detach() on Body, one of the inner classes of a grid. But on
screen, that would only update the number of items in the lower toolbar,
not the items in the grid themselves.
More ideas?
Ideally, imho, the grid should respond to modelChanged(). But I have
still no clue what should be in that method.
Regards,
Erik.

Hi Matej,
I just got a hint from a colleague: it might has something to do with
returning the wrong number of items in the dataprovider query. We
probably return UNDEFINED too often.
I'll look further into it.
Regards,
Erik.

If I remember correctly that only updates the existing items and ignore
new items. I am looking for a way to get the new items too.

Erik.

You need to call the update() method during an ajax request after you
have marked the items dirty.

Sorry, please ignore my previous e-mail. The behavior I saw was due to a
DropDownChoice I added to the toolbar. During a submit Wicket verifies
whether the ddc is visible. Unfortunately this leads to a call to
PagingToolbar.isVisible.
Back to square 1.
Regards,
Erik.

Hi Matej,
I finally found the bug.
When you are using a DefaultDataGrid it adds a PagingToolbar. PagingToolbar
overrides isVisible. In isVisible the total row count is determined, this
will cache the query result for this request. However, isVisible is called
/before/ the ajax listener is called. Therefore any changes to the grid
(like rowCount) are not used.
Regards,
Erik.
