Hi
I met the same problem, but in slightly different context - i have a CRUD SFSL and
it's instance member after creation was overwritten with new value:
| public class ItemEditor implements ItemEditorLocal{
| @DataModelSelection
| private Item item = new Item();
| ...
|
| public void persist() {
| em.persist(this.item);
| ....
| this.item = new Item();
| }
| ...
| }
|
by this i wanted to clean the form which displays current item. But instead i got my form
populated with recently entered data. Even after killing all cookies and refreshing the
page it was filled. I was completely baffled!
But it appears that most likely the problem is caused by javax.faces.model.ListDataModel -
it sets rowIndex to 0 when it has some data and then when injectDataModelSelections is
being called on a component the first element in a datamodel is picked up and injected
into member annotated with @DataModelSelection... hardly it was expected behaviour...
btw, there is a astounding code in injectDataModelSelection:
| if (null!=null)
| {
| setFieldValue( bean, null, name, wrapper.getWrappedData(dataModelAnn,
dataModel) ); //for PAGE scope datamodels (does not work for properties!)
| }
|
i mean null!=null ... what is that?
wbr, eugen.
