@ratuka Thanks I confirmed the bug exists

Has this been resolved?

[ratuka]

Unfortunately not. Even in the latest 1.6.0 snapshot it throws "uncaught exception: com.google.gwt.event.shared.UmbrellaException: Exception caught: This widget's parent does not implement HasWidgets"

I've traced this error down but I'm not sure how to fix it.
MaterialAutoComplete uses GWT SuggestBox and injects it's own TextBox into it. SuggestBox doesn't implement HasWidgets interface, so the TextBox can't be removed from it later.
But that's what happens when an item is added in "TEXT"-Mode (MaterialAutoComplete Line 353). MaterialAutoComplete tries to add the Box to a ListItem what causes the Box's "removeFromParent" function (of Widget class) to be called.
This Exception is also thrown when setting the SuggestOracle a second time, cause the TextBox is only instantiated once as an instance variable and reused while the SuggestBox is created new.

The TextBox shouldn't be reattaching itself in the display item. Will submit the fix tonight.
