Re: Problem with paged datatable and model

Hi Ilia,

multiple calls to #size() were discussed in this issue already:

https://issues.apache.org/jira/browse/WICKET-1766

Sven,

That's actually done:) I know this problem.
The problem for this particular case is in another place: ajax paging
links needs to know size of IDataProvider's data. And actually wicket
AjaxPagingLink invokes prover and corresponding model for that. So, I
mean, all ways to optimize bahaviour leads to wicket code...

Thanks,

Ilia

Hi,

in complex apps enable and visiblity can be linked with security settings
and so on

this is why you should override #onConfigure() and call #setEnabled() and
#setVisible() from there.

Thanks! In my case IDataProvider provides data from DB. And these
options leads to double query to DB... And that's a little bit
redundant...
DataProvider:

Do Wicket really need check enabling on every component within
hasError() method? Maybe somehow mark those components which can have
messages on it? Or as a workaround: check messages first and only
after that check for enable and visibility? I think, that it will be
even more time efficient: in complex apps enable and visiblity can be
linked with security settings and so on - so for first time it might
be time consuming.

Thanks,

Hi,

actually this is a known case where you have to call #detach() on your
model
by yourself:

onClick() {
service.delete(rowModel.getObject());

// let model reload the items
tableModel.detach();
}

Alternatively you can change IDataProvider#model() to provide a model,
which
can load a single item without loading the whole list of items first.

Guys,

Please help to resolve the following problem. There is datatable with
paging. Table propagated from LoadableDetachableModel. Also table is
under
form and contain action (AjaxFormSubmitLink) to remove a row within
table.

Problem: load() on the model invoked before actual action performed due
to
invoking isEnabled on AjaxPagebleLink in method Form.hasError(). So
model
loaded before actual changing of underlying layer.

For me it looks like an issue in wicket.
There are not so good work arounds: detach model after action or do not
use
LoadableDetachableModel.

What can you suggest?
