Hello,
I'm trying to use gwt CellBrowser and RequestFactory to show some
stored data as Cells in the cellbrowser. But I can't do it because of
the context of requestfactory.
Any Ideas ?
class CustomTreeModel implements TreeViewModel {
{
...
..
...
List<ComposerProxy> composerproxy = new ArrayList<ComposerProxy>();
private void setComposer() {
testRequestFactory = GWT.create(TestRequestFactory.class);
testRequestFactory.initialize(new SimpleEventBus());
request.getQuery("select a from Composer a").fire(
new Receiver<List<ComposerProxy>>() {
@Override
public void
onSuccess(List<ComposerProxy> arg0) {
//Here Is my problem, How
can I transfer the value of arg0 to composerproxy in order to use it
on my CellBrowser ()
// Tried with a for() to
insert each ComposerProxy individually and with a separate method
insertcomposerproxy(arg0) but didnt work
composerproxy=arg0;
}
});
}
}
public <T> NodeInfo<?> getNodeInfo(T value) {
if (value == null) {
setComposer();
// LEVEL 0.
// We passed null as the root value. Return the
composers.
// Create a data provider that contains the list of
composers.
//HERE IS MY PROBLEM. The composerproxy
variable is empty.
ListDataProvider<ComposerProxy> dataProvider = new
ListDataProvider<ComposerProxy>(
composerproxy);
// Create a cell to display a composer.
Cell<ComposerProxy> cell = new
AbstractCell<ComposerProxy>() {
@Override
public void render(Context context,
ComposerProxy value,
SafeHtmlBuilder sb) {
if (value != null) {
sb.appendEscaped(value.getName());
}
}
};
// Return a node info that pairs the data provider and
the cell.
return new DefaultNodeInfo<ComposerProxy>(dataProvider,
cell);
}
......
.....
.....
.....
}
PD: The getQuery() function works fine and the arg0 variable has data.
