enum2str not working correctly

Posted on by junior AX 1,552

Hi,

So i created a custom service, and when i try to call it from .net by doing the following:

DirPartyType = "Person" or DirPartType = "Per"

x code take it as person and my code enters the if statemenet that says dirPartyType::person. Why is that?

but if i try for example DirPartyType = "xx"  then i get invalid DirPartyType

Here's code in my service.

DirPartyType dirPartyType;
TestFactory::create(str2Enum(dirPartyType,_req.DirPartyType())


public static TestFactory create(DirPartyType _dirPartyType)
{
    if(_dirPartyType == DirPartyType::Person)
    {
        return new TestPCreator();
    }
    else if(_dirPartyType == DirPartyType::Organization)
    {
        return new TestOCreatorCreator();
    }
    else
    {
        throw error('Invalid DirPartyType');
    }
}

I have the same question (0)

    Hi Junior AX,

    Can you share where and how the service is validating or retrieving the party type value? The code you shared already has this value, I assume.

    Hi Junior AX,

    As per the MS document for str2Enum function (docs.microsoft.com/.../aa655065(v=ax.60)  Retrieves the enum element whose localized Label property value matches the input string.

    You have to use something like this;

    class Community

    {

       /// <summary>

       /// Runs the class with the specified arguments.

       /// </summary>

       /// <param name = "_args">The specified arguments.</param>

       public static void main(Args _args)

       {

           DictEnum dictEnum = new DictEnum(enumNum(DirPartyType));

           dictEnum.symbol2Value('PER');

           //DirPartyType dirPartyType;        

           //Community::create(str2Enum(dirPartyType, "x"));

           Community::create(dictEnum.symbol2Value('PER'));

       }

       public static void create(DirPartyType _dirPartyType)

       {

           if(_dirPartyType == DirPartyType::Person)

           {

               //return new TestPCreator();

           }

           else if(_dirPartyType == DirPartyType::Organization)

           {

               //return new TestOCreatorCreator();

           }

           else

           {

               throw error('Invalid DirPartyType');

           }

       }

    }

    Hi Faisal,

    It worked, but may you explain what is the difference between using DictEnum and what i originally did? and what does symbol2Value do?

    Hi Andre,

    in.Net i'm calling the service, by filling the contract parameters

    request.Customer = new customerContract()
{
    CustGroupId = "group",
    TaxGroup = "tax",
    //DirPartyType = "Per"
    DirPartyType = "Person"
};

    and as i mentioned in the code before, the value i filled in .Net is saved in _req.DirPartyType(), so i took this value and i passed it to TestFactory class

    DirPartyType dirPartyType;
TestFactory::create(str2Enum(dirPartyType,_req.DirPartyType())

    and again here's the test factory class:

    public static TestFactory create(DirPartyType _dirPartyType)
{
    if(_dirPartyType == DirPartyType::Person)
    {
        return new TestPCreator();
    }
    else if(_dirPartyType == DirPartyType::Organization)
    {
        return new TestOCreatorCreator();
    }
    else
    {
        throw error('Invalid DirPartyType');
    }
}

    Hi Faisal,

    I started getting this warning using your way:

    Warning Assigning a numerical value to extensible enum 'Extensible Enumeration(DirPartyType)' will yield unexpected results. Extensible enum values are not deterministically assigned to a numerical value.
