Great... p l e a s e upload it to the trunk asap :-)
And a side effect of this is, that in
qx.ui.core.EventHandler.js
line 227 crashes, due to an uncaught nil-pointer (or whatever this is called
in JavaScript):
if (this.__focusEvents[domEvent.getType()]) {
currentWidget = currentWidget.getFocusTarget();
}
if (currentWidget == null) return; // <<< I added this as a quick fix
// Ignore most events in the disabled state.
var type = domEvent.getType();
if (!(currentWidget.isEnabled() || this.__ignoreDisabled[type])) {
return;
}
