[Bug] In WEBGUI, when popping out the window, the grid becomes blank

[StephanWald]

When running the Grid in WEBGUI, and you pop out the Window, the BBjHTMLView does not automatically trigger a re-render.

We may want to catch the JS side event for undocking and re-render the grid in its initial state, perhaps we can also do better and fill it with the most recent data and formatting.

It's already pretty clear that the pop-out cannot be lossless as the server has no permanent trace of the grid status.

There is a callback in the window listeners object in javascript options :

These callback functions are called in all connected browser windows:

• windowDocked fires after the webswing window has been docked
• windowUndocked fires after the webswing window has been undocked

This is how you can determine the undock state of the window:

In Javascript:
webswingInstance0.getRenderedWindows()[0].getDockState() (returns
0=docked, 1= undocked, 2= toBeUndocked)

In Java:
WebswingUtil.getWebswingApi().isUndocked(Window window)
