am I the only one for whom setting setSelectOnFocus(true) on a TypedComboBox has no effect?

What I am experiencing (GXT beta 4 / GWT 1.5 / FireFox 2.0) is that when moving through a panel's element with the Tab key, the combobox does not select when it's its turn in the tab order. However, regardless of what I set in setSelectOnFocus, the combobox will get the tab focus again after all other elements and that time select its value.

Small glitch, just wanted to report it though.

Congratulations to the great work otherwise,
