Hi,
I'm very young on the Wicket planet, so please excuse my simple question
related to DataView/IDataProvider
My configuration:
1. I use a DataView (MyDataView)
2. I added a PageNavigator to MyDataView
3. I defined a IDataProvider attached to MyDataView (MyDataProvider)
4. MyDataProvider has a not-serializable field (MyField)
5. MyField is used in the method MyDataProvider.size()
6. I use Wicket 1.4.0
What I do:
1. In the method MyDataProvider.detach() , I nullify MyField (MyField = null)
What happens:
1. When I navigate through pages, I get a NPE in MyDataProvider.size() as
MyField became null
How I fixed it:
1. I overrode in MyDataView the method getDataProvider(). Didn't work. I
noticed that this method is never invoked
2. I tested again null in MyDataProvider.size(). If MyField is null, I just
reinitialize it. It works
My question is if this solution is the optimal one, or there is a better one?
Thanks,
kaltman
