Re: SafeHtmlTemplate display alternative (backgorund- or cell-) image inside (mgwt)CellList-Item if image not available

A bit unfortunate that GWT has a CellList and MGWT has a CellList and both are totally different. Maybe you should ask this on a MGWT mailing list?

But given that MGWT CellList is a Widget you can add any event handler to it using addDomHandler(). I am not sure about the error event but I would try adding a ErrorEvent/ErrorHandler to the CellList. If it really triggers then you should be able to figure out the <img> element and change its src attribute if loading has failed.

And yes you need an <img> element because no event exists that tells you if a CSS background image has been loaded or not.
