Hi,

With a specific application, the event loop is not launched because in PartRenderingEngine.someAreVisible is returning false.

l1206, win.isToBeRendered is returning true anw win.getWidget() is null

Based on the comment int the method

// Note: isToBeRendered() == true => win.getWidget() != null
			// but I'm not sure whether there is latency between setting
			// toBeRendered and the creation of the widget. So, keeping
			// both tests seems prudent.

this should not be possible a common use case...

Do you have ideas a on what can be the reason?
Do you have ideas on where I can put breakpoints to investigate?

Thanks by advance for any help

Hi,

answer to myself, it was due to the fact that we are using a Custom Renderer Factory which in this case returns null.

Hope it can help someone later on. Not sure if it worth updating the comment in the code for this specific use case.
