I have some threads that perform networker requests and then create ui
elements based on the results of these request.
These elements (markers) are then added to a map. But at this point the app
sometimes crash with a ConcurrentModificationException.
The function in my threads that is called to add elements (markers) to the
map is inside a
```
Display.getInstance().callSerially(new Runnable() {
}
```
block. I thought it was how we are supposed to "resync" results of some
threads with the EDT one but it doesn't seem to work as I expected as the
MapLayout is sometimes returning a ConcurrentModificationException when
performing the layout (probably because some threads are adding markers
components when the EDT is trying to perform the layout)
So how can I safelly add components to a container (a map) from multiple
non EDT threads?
Thanks
