Receiving error " 'object' does not contain a definition for 'ToList' ” when I am trying to create a List

Thank @Shawn Burt it Actually returns the same “ApproveInfo”. Here is the class. As it pointed out earlier all works perfectly when I copy the code to each graph.

public virtual IEnumerable<ApproveInfo> GetApproversFromNextStep_Extension(SourceAssign Source, EPAssignmentMap AssignmentMap, int? CurrentStepSequence, string Action)
{
    ApproveInfo approveInfo;

    //Do stuff here

    yield return approveInfo;
}

 

and below is part of the method I call the above:
 

public static EPApproval GetApprovalInfo(PXGraph Base, dynamic Document, EPApproval ApprovalBase, string Action, dynamic Approval)
{
    // Do some stuff here

    List<ApproveInfo> approvalSealedData = new List<ApproveInfo>();
    // I Get error on the next line
    approvalSealedData = Approval.GetApproversFromNextStep_Extension(Document, assignmentMap, stepBase.Sequence, Action).ToList();

    // Do some stuff here
}

Hey  @markusray17  here again I am using Reflection to create a generic method that works for all graphs I need it for. You might be able to help here as well since it appears the similar issue of Cach.CreateCopy you healped with. The method works in each individual graph but not as generic one.

var test = Approval.GetApproversFromNextStep_Extension(Document, assignmentMap, stepBase.Sequence, Action).GetType();

Console.WriteLine("The type of this object is: " + test);

//do this inside GetApprovalInfo and post the result

@aaghaei - See above code. Run it in debug and tell us the result.

You’re going to have to post more of this code. For example, how is GetApprovalInfo being called?

I echo what Sean Burt said above...if you are going to use reflection, you need to understand the types you will be dealing with in your code. The abstraction has to be flexible enough to deal with the various object types that are going to be passed through your code. Also, I don’t think you are properly instantiating the Cache Extension… if Approval is the cache of some graph, then it should prob be something like this:

var test = Approval.GetExtension<GetApproversFromNextStep_Extension>(obj), where obj is some instance of that type. Again, you should probably be checking the types of the objects being passed if we’re using reflection (this is why your code works fine in individual class types, but not as a general abstraction).

I think this manner of trying to invoke the extension is probably just throwing an error, unless I’m missing some intermediate method you’ve created here...

Approval.GetApproversFromNextStep_Extension(Document, assignmentMap, stepBase.Sequence, Action)

@aaghaei , I’m so flattered to be included… but I’m not a developer. 😐 Programming code isn’t one of my superpowers. Good luck!

@aaghaei Many moons ago I coded - maybe someday again. Until then here is my contribution - “look for a missing semicolon” ;)

Thanks a lot for looping me @aaghaei  :)
