C# struct in E10 BPM editor produces compiler error


(system) #1

It’s not really a bug of any kind. It absolutely makes sense. You are adding code inside of a method that their framework calls. You are trying to jam code in that is not intended to be there. That is no fault of Epicor’s. That being said there is supposedly in the latest version of Epicor a Global Variables section where you can define stuff outside of the methods a custom code action.  Invoke External Method is not to be used that way, but to your point you could create an external DLL and include that into the Using and References tabs.

That's crazy.  How the heck does Epicor expect people to use their environment if the parser doesn't handle simple syntax.  Is Epicor aware of this and acknowledge there is a problem?  I agree, I don't want to write "bogus" code just to get the system to compile.  Would a better solution would be to write it in Visual Studio and use the Invoke External Method?


(system) #2

To keep the code clean and reduce issues as Epicor releases updates, I created a separate assembly in Visual Studio called BPMUtilities that deals with actual writing of the message queue and associated structure.  I then added the assembly as a reference in the data directive and called the methods to do the writes. 


Thanks everyone for your input!


(system) #3

Has anyone run across difficulty in using structs in E10 BPMs?  The following code, all by itself, will not compile complaining there is a missing end bracket }


struct CustomerQueueData
{
    public string action; // action: Insert, Update, Delete
    public string custid; // CRM Account: accountnumber
    public int custnum; // CRM Account: fcii_custnum
    public string shortchar01; // CRM Account: accountid
}; 




(system) #4
I don’t think you should have the semi-colon at the end

Thanks for reply Scott.  It fails the same with or without the semicolon.  I have even removed the comments with the same result.

(system) #6
Could you provide the error message, if any? Or does it just say it's not compiling ?

(system) #7
The very last semicolon? or the last in the list inside the brackets?

============

"I don’t think you should have the semi-colon at the end "
 

(system) #8

The very last semicolon.  Like this:

struct CustomerQueueData
{
    public string action; // action: Insert, Update, Delete
    public string custid; // CRM Account: accountnumber
    public int custnum; // CRM Account: fcii_custnum
    public string shortchar01; // CRM Account: accountid
}


In the wild, I've seen it both ways.  Visual Studio doesn't care either way.

If you put that inside of a BPM the curly braces are going to conflict with how it’s compiled in the background you end up with something like.

 

Private static void Bpm_CustomAction01(){

 

    Struct myStuff{

         Public moreStuff;

    }

 

}

Could you provide the error message, if any? Or does it just say it's not compiling ?

Putting the extra curly braces in there will "fix it" however this is strongly discouraged, you are banking on Epicor not changing the way they generate their code.


However for example sake

Epicor code generates like this

CustomConde()
{
 //YOUR CODE HERE

}


So if you want to "game" the system you could close / open your own curly braces to create your own structure... for example you could do


CustomCode()
{

 //Your Code starts here
  MyCustomMethod();
 }

 struct CustomerQueueData
 {
   public string action; // action: Insert, Update, Delete
   public string custid; // CRM Account: accountnumber
   public int custnum; // CRM Account: fcii_custnum
   public string shortchar01; // CRM Account: accountid
 }

 private void MyCustomMethod()
 {
  //Use your struct



 } //This curly brace is provided by Epicor


But this is highly hacky and I don't think you should use it.Â

That error says you are missing a '}' which you very well could be. Can you paste the whole BPM or go over it yourself and make sure all the brackets are matching. Only other thing is struct using the name space system. So maybe in your usings add using System;

(system) #13
All I have in the BPM is the listed struct. I removed all the other code as I was debugging and found the error would occur with only the struct statement.

(system) #14

That is because of the curly braces. Please review Jose and I’s last posts for clarity on why that is occurring.
