Yep, thanks a lot Paul!
Now the alert shows me: "Form object: [Canvas ID:cnv_fu1]"
Looks good to me, until I try this:
var myvar =
c...@be.sofico.montelli.mmc.client.custom.widgets.upload.srafileupload::submitDoneInternal
(Ljava/lang/String;)(filename);
I do have this defined on SRAFileUpload though:
public int submitDoneInternal(String filename) {
SRALogUtil.debug("submitDoneInternal called on form " +
uploadTargetId);
return 10;
}
The generated JS looks like this:
function defineBridgeMethodSubmitDone(){
$wnd.submitDone = function(canvasname, filename){
$wnd.alert('Upload done: ' + canvasname + ' - ' + filename);
var cnv = eval('$wnd.' + canvasname);
$wnd.alert('Form object: ' + cnv);
var myvar = cnv.submitDoneInternal(filename);
$wnd.alert('Incoming: ' + filename + ' Processed: ' + canvasname +
' Result: ' + myvar);
}
;
}
function submitDoneInternal(filename){
$clinit_907();
$debug(impl, 'submitDoneInternal called on form ' +
this.uploadTargetId, null);
return 10;
}
Surprisingly, I get JS error "submitDoneInternal is not a function".
Any ideas on this?
