Example network MyConfig throws exception

[valbucci]

Hi, I tried running MyConfig, but I get the following error:

(omnetpp::cChannel)temp: Fatal: Direct deletion of a channel object is illegal, use cGate's disconnect() or reconnectWith() instead; ABORTING -- in module (SimpleUnderlayConfigurator) SimpleUnderlayNetwork.underlayConfigurator (id=2), at t=0s, event #2

I ran the debugger and the issue seems to happen in SimpleNodeEntry::SimpleNodeEntry() at SimpleNodeEntry.cc:143 where tempRx and tempTx are deleted.

Do you know how I can fix this?

I think this is not a solution, but I figured that commenting out those lines gets rid of the error, though, I'm not sure if the simulation environment will work appropriately after this change.

I didn't like this fix, so I dug a bit deeper and I think it must have something to do with an update from OMNeT++ (I'm running version 5.7).
In /OverSim/src/underlay/simpleunderlay/SimpleNodeEntry.cc I replaced the lines 143-144:
delete tempRx;
delete tempTx;

to

tempRx->setDisabled(true);
tempTx->setDisabled(true);

Again, I am not sure if this a solution, but the simulation environment runs. If I understood correctly, this way the cDataRateChannel objects don't get deleted, but will discard all messages sent on them.
