Hi Peter

Unfortunately, the call of the methods this->removeObject( "propStateMachineName.get()" ) didn't work. I can see on the taskbrowser that the statMachine isn't removed from the component (the stateMachine is desactivated) wahen id a cleanup on my component

Now , in the cleanup, i call the method engine()->states()->clear(). It its ok. when i do a cleanup on my component, the statemachine is removed from the component.

In case of submachine, how can i remove the submachine on my component

Normally, unloadStateMachine should remove the taskobject too. I don't
know yet why this didn't happen in your case, but you can by-pass
this by adding to cleanupHook:

void
Component:cleanupHook()
{
scripting()->unloadStateMachine(propStateMachineName.get() );
// work around bug not removing the object representing the SM:
this->removeObject( propStateMachineName.get() );
}

Hope this helps !

Hi all

I have one component with a state Machine. The name of the file that contains the stateMachine is a property. So i load the stateMachine in the configureHook (after read the property)
I want te stop/cleanup/configure and restart the component. I have a Log ERROR when i want to reconfigure the component ( Parse error at line 32: Semantic error: TaskContext 'Component' has already an Object named 'smTest').

Here is an example of the code
** Fonction appelee au demarrage du composant
* Role : configurer les liens avec les autres composants
* @return true si configuration OK false sinon
*/
bool
Component::configureHook()
{
bool res = true;
this->scripting()->loadStateMachines( propStateMachineName.get() );
m_ptrSM = this->engine()->states()->getStateMachine("sm");
if ( m_ptrSm != NULL)
{
res = true;
}
return res;
}
void
Component::stopHook()
{
m_ptrSM->stop();
m_ptrSM->deactivate();
}
void
Component:cleanupHook()
{
scripting()->unloadStateMachine(propStateMachineName.get() );
}

Of course , i can load ths stateMachine only if my pointer mPtrSM is NULL, but it seems to be a bad solution. It would be better if it was possible to call a method for doing that.
How can i solve this problem ?
