Hello Guys,
I am writing some code that dynamically modifies a tree. How it works is:
1. User Clicks on a combo box and enters a regular expression
2. On keypress (enter) the data is sent back to the server to set it in session
3. A tree holding some data is refreshed (so that the server sends back the relavant filtered data) [This step cannot be done on the client for a variety of reasons]
The setting of the filter, and the server side code works perfectly. Cause if i pass the filter via a url before the page is loaded, it shows properly filtered data.
However when i try to change it via the combo box, it fails.
And i get a wierd error on the combo box instead of the tree.
Some Code samples:
The code to set the filter and reload the tree
The Tree refreshing code: I am not exactly sure what all to provide from here, since its a lot of code. I am hoping for some pointers from the general picture that i painted, and can provide proper code samples to take it further. (I am still trying to recreate a standalone setup that can also reproduce the problem.)

2. Developer Console Trace:
Posting in a separate post below (Cause its huge)

Code:
final ComboBoxItem filterInput = new ComboBoxItem("Filter");
filterInput.setType("comboBox");
filterInput.setWidth(200);
filterInput.setShowTitle(true);
filterInput.setDefaultValue(filterPattern);
filterInput.setValueMap("Test"," test 2", "test 4" , "test 5");
filterInput.addKeyPressHandler(new KeyPressHandler() {
@Override
public void onKeyPress(KeyPressEvent event) {
if(!"Enter".equalsIgnoreCase(event.getKeyName())){
return;
}
System.out.println("On key press handler called.");
String currFilterVal = filterInput.getValueAsString();
FilterServiceAsync service = GWT.create(FilterService.class);
service.setActiveFilter(new FilterDTO("Ad Hoc", currFilterVal), new AsyncCallback<Void>() {
@Override
public void onSuccess(Void result) {
drillDownContainer.refreshData(); // This is a custom container inheriting from VLayout, mostly irrelevant to this problem
drillDownTree.recreateTree(); // This is a function i wrote to remove all the children of the tree and reload it from the server.
}
@Override
public void onFailure(Throwable caught) {
com.google.gwt.user.client.Window.alert("Filter setting failed: " + caught);
}
});
}
});
