Re: Check Group selected items called from other form loses the checked values

[Francois Meillet]

Hi,

Use a ListView.

The model of the second form is not updated until the form is submitted.
You need to perform a submit if you want to see this model updated, and the 
correct value for tst.getCheckedTestBeans().size().

If you want to avoid the manual submit phase, you need to use Ajax.

Please find here your code slightly modified.

Re: Check Group selected items called from other form loses the checked values

[ganea iulia]

Hello, Thank you for the samples.
But I will explain again what I have:

I have two forms on my page.
In the bottom form I have a RefreshingView component, with check all
checkbox in the header, and check components for each items.
In the top form there is a link, where I need to get the checked items from
the second form (the bottom form);

This is what I have done:
For checkAll and the individual checks I have used CheckGroup,
CheckGroupSelector and Check.

The issue is that because the refreshing view refreshes the model at every
server roundtrip, when I check on item, the check doesn't maintain it's
value, because it receives every time a new model.

So this bit from the RefreshingView always returns a new model which makes
the checks to dissapera:
@Override
protected Iterator getItemModels() {
List lst = SpringCtx.getAppDB(TestBeanDao.class).selectAll();
List models = new ArrayList();
for (TestBean tstSN:lst) {
IModel modTst = new Model(tstSN);
models.add(modTst);
}
return models.iterator();
}


Isn;t there any way that I can still use the CheckGroup and Check
components? As this comes easy when it is needed a CheckAll functionality.

Thank you

Re: Check Group selected items called from other form loses the checked values

[ganea iulia]

Hello,

I have actually made this to work by adding this behaviour to the
checkgroup:

group.add(new AjaxFormChoiceComponentUpdatingBehavior() {
private static final long serialVersionUID =
1654345477970524731L;

@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(group);
}

});

However, now I face following issue:
If I replace my ListView component, with a RefreshingView, I cannot check
any of the checks from the items. I check it, but then it gets unchecked
right away.
This is because the RefreshingView repaints its model at every roundtrip to
the server.

I have tried this:
http://stackoverflow.com/questions/12282492/add-row-to-refreshingview-without-repainting-entire-refreshingview
by setting:
listOfItems.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());

But it did not change a thing for me.

Please guide on how to have a Check for every item of the RepeatingView,
that can be checked.

Thank you.

Check Group selected items called from other form loses the checked values

[ganea iulia]

Hi,
I have 2 forms.

Bottom form = testForm
- I have a listview with checkboxes.
As I needed a checkAll control also, I have uses CheckGroup,
CheckGroupSelector and Check wicket components.

Top form = testForm0
-I have only an link

The use case is the following:
I check one item (or all) in bottom form, but then I need to get the
selected values when click on link in top form.

The check doesn't do submit so the values are not retained. I alsways get
the
size = 0 message.

Could you tell me how I can manage this?

Here is the code:
=HTML=

   












Name
Code


Id
