Hi Liu Hsien,
As Olivier ECKERT told it, this kind of issue normally has to be handled through the support channel as it is for technical purpose, so next time don't hesitate to contact your support center to get help for such problems.
Anyway, your issue has been filed in our database as:
#16679 - ui.Interface.frontCall failed with long arguments
It will be fixed in next GAS release.
Meanwhile, the following change in your "FGLASDIR/tpl/SetAjax/gwccore.js" file should clear the problem:
change:
function _CreateDoc(ml){
return domParser.parseFromString('<div xmlns="http://www.w3.org/1999/xhtml">' + ml + '</div>', 'application/xhtml+xml').documentElement;
}
into:
function _CreateDoc(ml){
var xmlDoc = domParser.parseFromString('<div xmlns="http://www.w3.org/1999/xhtml">'+ml+'</div>', 'application/xhtml+xml');
xmlDoc.normalize();
return xmlDoc.documentElement;
}
Best regards,
Guney
