Description Florian Best

There is a javascript traceback in the School wizards if no school exists yet. I don't think it breaks something.

TypeError: Cannot read property 'length' of null
    at declare.getSearchWidgets (http://10.200.27.30/univention-management-console/js_$20151011154150$/umc/modules/schoolwizards/UserGrid.js:92:15)
    at declare.buildSearchForm (http://10.200.27.30/univention-management-console/js_$20151011154150$/umc/modules/schoolwizards/Grid.js:215:23)
    at declare.buildRendering (http://10.200.27.30/univention-management-console/js_$20151011154150$/umc/modules/schoolwizards/Grid.js:69:9)

this.schools is null instead of a empty list:

		getSearchWidgets: function() {
			var schools = lang.clone(this.schools);
			if (schools.length > 1) {
				schools.unshift({id: '/', label: _('All')});
			}

What is the impact of this traceback? Error message to the user? Faulty behavior of the UMC?

The module doesn't render and is therefore not shown. But there is a non-closeable pop up to create a school which opens the school wizard successfully when clicking on it.

This affects only multi server environments since the installer creates a OU by default in single server mode.
