We have a page with a non-editable ComboBox on top, and below that is a GWT Frame element which loads an external web page (hosts the page in an iFrame internally). If I expand the combobox, then click somewhere inside the iFrame, the ComboBox does not collapse. If I click next to the ComboBox, it collapses as expected.
Steps to reproduce the problem
Create a page with a non-editable ComboBox and a control that uses an iFrame
Expand the ComboBox
Click inside the iFrame
The ComboBox collapses when it is blurred.
The blue focus hilight inside the ComboBox changes to gray, but the drop-down does not collapse.
Debugging already done
The NativePreviewEvent that the TriggerFieldCell is watching for does not fire when clicking inside a different iFrame.
Not sure if this is even possible? But it is definitely a bug for our users, who don't know or care about what we're hosting in an iFrame and what we're not. If it can't be solved for the iFrame case, is there any alternative to an iFrame we could use to host other pages that will give us blur events properly?
