Re: CellTable keyboard events troubles in Chrome

I know this is not a "funny" question, but if someone already had this kind of issue or have any suggestion, help would be very appreciated as I could not make it work correctly in Chrome.

GWT-team ?

Thanks

Hi All,

After a search on the internet and in this group I didn't found help for the issue I have.
So I ask here if someone has any advice or workaround.

I just tried basic example of CellTable found here http://www.gwtproject.org/doc/latest/DevGuideUiCellWidgets.html, and put the cellTable in an empty VerticalPanel somewhere in my app.

In Chrome only, the example doesn't work correctly : almost all keyboard events have no effect. Only Delete, Backspace, CTRL-Z + other CTRLs and ENTER keys work. It is impossible to type in some text : alphanumeric key events have no effect on the content of the cells.

With other browsers than Chrome the CellTable example works without any problem !

For the test I use :
GWT 2.5.1
Test NOT OK : Chrome 32.0.1687.2 dev-m Aura
Test OK : Firefox : 24.0
Test OK : Opera : 12.11
Test OK : Safari : 5.1.7
(no test on IE as I have only IE6, for other tests purpose...)

Thank you for your help.
Yves
