GridAdvance "isEditable" Property seems to be buggy

Hi everyone,

I'm currently facing an issue with "GridAdvanced" widget, which seems to be a bug.

I'm using ThingWorx 9.1.8-b845.

What I'm trying to accomplish is basically pretty simple.

I just call a service called "GetGroupManagement" (whenever the mashup is loaded) which gives me a boolean "true".

I connect this later on to the properties of "GridAdvanced" widget: (Visible: false by default, isEditable: false by default).

So what happens is the widget is being shown but is not editable. As soon as I add another event trigger (e.g. "DoubleClicked" trigger from "GridAdvanced") to the same service, the "GridAdvanced" is now editable.

Does anyone see the mistake here? It seems to me like a bug in the "isEditable" property of "GridAdvanced" which initially not trying to fetch the value from the service, unlike the other property e.g. "Visible". 

I've found a not so intuitive work around solution by also triggering the call to the service when the grid is double clicked, but I'm not so satisfied with it 😞

Any suggestions? Thanks in advance.
