Hi All,
I'm currently working myself into orocos and struggle about a strange problem.
I try to call a command of TaskContext-A from within TaskContext-B and get
allways the error message:
---------- snip --------
pure virtual method called
terminate called without an active exception
Aborted
Press Enter to continue!
---------- snip --------
A call of the same command from within ORO_main works just fine!?!?
Does anyone have an idea what I'm doing wrong?
Error in calling commands from another TaskContrext
Can you send us the pertinent code that doesn't work? That will help
us to help you ...

Error in calling commands from another TaskContrext
Hi,
please find attached the a sample to reproduce my problem.
To build just unpack and call make
(assumed that orocos is installed under /usr/local)
I want to call the command "StepControl.MoveTo_A" from within the task context
StateInfo.
If I call the command "MoveTo_A(100)" in the TaskBrowser all works as
expected. To call the command from the task context "StateInfo", I created a
command and also a methode but cot the same error for both ways.
To reproduce run "robotcontrol" and call "MoveTo_A(100)" in the TaskBrowser.
This sould result in a list of Debug outputs.
Than try "StateInfo.MethodCallMove" or "StateInfo.CallMove" to see the error.
Thanks in advance for any help
Joerg

I haven't looked for yet what's causing the crash, but what is definately
wrong is this piece of code:
void StateInfo::updateHook()
{
// Read the inbound ports:
MyDataStruct mds;
mds.A = inData_A.data()->Get();
if ( mds.A != -1 ) {
log(Debug) << "Got valid Data for A !"<< mds.A <<
Logger::endl;
}
Command move_A =("MoveTo_A");
getPeer("StepControl")->commands()->getCommand
if(move_A.done() == true){
log(Debug) << "Command MoveTo_A is done!" << mds.B <<
Logger::endl;
}
}
The move_A object has *local* state and is a *copy* of the command
in 'StepControl' (all commands are copies and independent of each other). So
move_A.done() will always be false since you did not call move_A() .
So you need to store move_A as a member of StateInfo.

That's also the reason why it crashes. The C++ command object move_A has been
destroyed before the receiving task could execute it, but it was already
queued... so eventually the receiving TC executed a deleted command.
The solution is to make move_A a member variable of your class.

Jop, that was the problem. Now it works as expected.
