[Seaside] Ajax and error management

[Thierry Thelliez]

I finally found a simple way to do it :-)  The issue was not really
about the complexity of the JS function, but I could not find how to
hook to the onError call.

Here a solution:


onError:  ( 'alert(xhr.status); alert(thrownError);' asFunction: (
Array with: 'xhr' with: 'ajaxOptions' with: 'thrownError' ) ) );
