That sounds pretty conclusively like a bug in Ur/Web itself somewhere,
if you aren't using the FFI! However, I see that your application /is/
using the FFI. ;-)
It would be very helpful if you could try to isolate the problem to a
test case that doesn't use the FFI.

Hi,
I have developed a GUI with a lot of push pin buttons that are
associated to boolean sources. When the button is pushed, it sets its
source to true. When the button is released, it sets its source to
false. The problem I am facing is that after pressing those buttons
some times, the JavaScript runtime is showing alerts saying:
cannot read properties _sources of null
cannot read property c of undefined
Is this a bug in the JavaScript runtime?
I did not have time to try to isolate the code that trigger the alerts
yet. In any case, the complete code is available in

Sincerely,
Saulo
