[FIXED] Bug when adding a combo box

[zaccret]

Hi,

I am trying to add a combobox in a FormPanel. When I click on the combobox to unroll it, I get an exception in the GWT devlopment shell and I can't yet roll/unroll the combobox.

Here is the code :

public void onModuleLoad() {
Viewport viewport = new Viewport();

final FormPanel panel = new FormPanel();
panel.setHeading("Login panel");
panel.setWidth(400);

TextField userTextField = new TextField();
userTextField.setFieldLabel("User name");
panel.add(userTextField);

final ComboBox combo = new ComboBox();
combo.setFieldLabel("File");
final Store store = new Store();
BaseModel model = new BaseModel();
model.set("text", "N/A");
store.add(model);
combo.setWidth(100);
combo.setStore(store);
panel.add(combo);

viewport.add(panel);

RootPanel.get().add(viewport);
}Here is the stack trace :

Mmm. This was in hosted mode.

It works in web mode... So GWT bug ?

[darrellmeyer]

Your test code works in both host and web mode (ie, ff) with the latest code. Try testing your code again when beta 3 is available which will be later today.

It still not works with beta3. The same error in hosted mode :

[darrellmeyer]

What browser, browser version, and OS are you using?

It looks like it is the same bug. The change I made will be in RC1.

[zaccret]

What browser, browser version, and OS are you using?
I'm working on Windows XP. The bug reproduces only in hosted mode. It works in web mode with both Firefox 3 and IE6.
