Graphedit 1.4 crashes in some situations

[Vittorio]

I experiment a lot with the Graphedit+ and find it extremely useful. But in some situations I experience very unpleasant surprises. To reproduce one of the situations please do the following.
1. Plug any vcl-compatible USB WEB-camera with the snapshot-button. The corresponding filter exposes in that case 2 output pins, still and capture.
2. Put the filter into the graph
3. Connect both pins to two different sample grabbers and their output pins to the different Null-renderers. The typical situations for the the programming of the custom still capture routines.
4. Rung the graph
5. Pull off the WEB-Cam during the graph is running, yea I know, this is a nasty trick but such situations must be catched and processed by the software
6. Stop the graph
7. Reattach the camera to the computer
9. Add another instance of the filter for the camera
10. Try to reattach the capture and the still pins of the freshly added filter to the inputs of the corresponding sample grabbers

Et voila, Graphedit throws an unhandled exception "System.OutOfRangeException" and exits

Any suggestions?

Don't do that.

Thanks for reporting, we'll look into this issue. If you find more bugs please post here.

This problem was caused by the necessity to develop a background monitor for some specific customized camera. I've tried to develop scenarios which would allow me not to destroy and to rebuild the complete quite complex graph but only reattach the filter. This could be easily done with the open source version of the graphedit. Since GEP provides a lot of additional useful functionality I wanted to return back to it and experienced this problem.
