Hi!
We are using the class MapContent together with the StreamingRenderer to
render a bunch of different layers. This works fine, but now we want to
render the same layers with a second MapContent. The problem is that when
calling `dispose()` on the first MapContent, that also all layers are
disposed and the data sources are closed. So that the layers can not be
used anymore in a second MapContent.
I could simply skip the call to `MapContent.dispose()` and then dispose the
layers manually at the end. But this shows the error message "Call
MapContent dispose() to prevent memory leaks", which I do not want to show
to the users of our library.
For now, I sub-classed MapContent and overwrite `dispose()` and
`finalize()`, but this feels like a hack. What else could I do? Why are
layers disposed when disposing MapContent?
Thanks,
Tobias
