Well, the patch for issue GWT 7139 solved the problem. This is the issue http://code.google.com/p/google-web-toolkit/issues/detail?id=7139&can=4&colspec=ID%20Type%20Status%20Owner%20Milestone%20Summary%20Stars
This is the link to the patch: https://github.com/nmorel/gwt-issue7139/wiki I've edited the patche's *.gwt.xml to use this solution for ie9 as well and it worked. In conclusion, this is what I understand: DataGrid on GWT 2.5.0, when using IE (9 or 10), does not catch click events (and all other kinds of events) unless you click on a row which is already selected. This problem can be solved by this patch https://github.com/nmorel/gwt-issue7139/wiki -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
