Whenever I see problems like this I try deferring the focus and/or
listener registration from the event which creates a new widget like
this. The Tree implementation includes some fun internals which change
focus on things to ensure visibility and handle keyboard input.
Example:
public void onClick(Widget w) {
DeferredCommand.addCommand(new Command() {
public void execute() {
createMyWidget();
}
});
}
