Location of nodes in Omnet/Inet - omnet++

Question

I am using the LinearMobility module of Inet in a compound module, I need to read the position of the node to use in the .cc code. I have looked for the answers and I came across this code:
cModule *host = getContainingNode(this);
IMobility *mobility = check_and_cast<IMobility *>(host->getSubmodule("mobility"));
... = mobility->getCurrentPosition();
But unfortunately this code throws a run time error, probably there is something wrong with the check_and_cast because the getCurrentPosition() method for the mobility does not work. (I have also tried dynamic_cast instead of check_and_cast bust still the code throws an error ).
The error I receive is :

I also took a shot from the block of code in my source file :
screenshot of the above-mentioned 3 lines of code
As you can see the getCurrentPosition() method does not work, and when I comment 2nd and 3rd lines of the above-mentioned 3 lines of code, simulation runs without any problems.
This is the copytic.cc ( copytic.cc is only used to test the 3 line code in order to get the position of nodes and does not have any other purposes ) :
