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<IModel<TestBean>> getItemModels() {
List<TestBean> lst = SpringCtx.getAppDB(TestBeanDao.class).selectAll();
List<IModel<TestBean>> models = new ArrayList<IModel<TestBean>>();
for (TestBean tstSN:lst) {
IModel<TestBean> modTst = new Model<TestBean>(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
