Module SDK creating a custom Task Sequence

[ FlexSim 22.2.2 ]

Hello there,

I'm developing a behavior for a custom machine and I need it to create a Task Sequence which an opreator will interact with a flowitem being processed (Take it for a trip, delay and return it).

I started running into problems while using the Task Sequence class (as recommended by the documentation) to generate and dispatch these tasks via DLL, getting the following excpetions:

I've also tried using the deprecated methods, with no results.

What may be causing this behavior? How do I sucessfully create and dispatch Tasks Sequences using the DLL?

@Patricia_brenny R Have you used the C++ debugger to check all the variables and what their value is? I don't see anything really strange. Except maybe that I think that holder is the current machine so I think you can write: treenode currentMachine = holder; (which would make it shorter and faster)

Yes, I've used it and it has stored all the values that were supposed to be stored, just this "access denied" message when using the add task method for no apparent reason. We implemented the currentMachine like that as to odd out any other issues but it doesn't seem to be the problem.

The create() method is static so I think you need to use is against the class and not the instance.

TaskSequence inspection=TaskSequence::create(operador,1,0,1);

in FlexScript it's:

TaskSequence inspection=TaskSequence.create(operador,1,0,1);

hmm we tried that and got this, then proceeded to use it against the instance which created no error. Also don't understand why.

Yes I wrote the FlexScript initially, but try using the scope resolution operator '::' to access the static method.

I could resolve it by using the deprecated methods as follow:
