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');
    }
}

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.
