With reference to the function defined in execFlowFunctionObjects.C:

void execFunctionObjects
(
    const argList& args,
    const Time& runTime,
    autoPtr<functionObjectList>& folPtr
)
{
    if (folPtr.empty())
    {
        if (args.optionFound("dict"))
        {
            IOdictionary dict
            (
                IOobject
                (
                    args["dict"],
                    runTime,
                    IOobject::MUST_READ_IF_MODIFIED
                )
            );

            folPtr.reset(new functionObjectList(runTime, dict));

        }
        else
        {
            folPtr.reset(new functionObjectList(runTime));

        }

        folPtr->start();
 
    }

    folPtr->execute(true);
}

it appears that the private member "parentDict_" of class "Foam::functionObjectList" is reset to a null object between the constructor

"folPtr.reset(new functionObjectList(runTime, dict));"

and the call

folPtr->start();

Moving "folPtr->start();" inside the "if" body fixes the problem:


void execFunctionObjects
(
    const argList& args,
    const Time& runTime,
    autoPtr<functionObjectList>& folPtr
)
{
    if (folPtr.empty())
    {
        if (args.optionFound("dict"))
        {
            IOdictionary dict
            (
                IOobject
                (
                    args["dict"],
                    runTime,
                    IOobject::MUST_READ_IF_MODIFIED
                )
            );

            folPtr.reset(new functionObjectList(runTime, dict));
            folPtr->start();

        }
        else
        {
            folPtr.reset(new functionObjectList(runTime));
            folPtr->start();
        }
    }

    folPtr->execute(true);
}
