Hi Shamasis,
I would like to ask for more details on this error.
I am working on single-page JS application, which provides data in reports displayed in jQuery tabs. I encounter this error few months ago, but it does not happen all the time. That is why it is not critical for me, rather annoying. However this makes it hard to reproduce and fix.
I believe it was related with timing. Maybe container was not ready on time? This is really hard to explain, because I render HTML template and attach result to DOM (with jQuery) and later I run code that parses and loads JSON data and creates chart.
Regrards,
