Hi guys,
This is probably a really simple question, but something I haven't been able to get on top of yet.
I have a message coming into the broker that has an RFH2 user portion. One of the values I am retrieving is a simple byte -- either a 0 or 1. I need to base some conditions in my ESQL code based on the value of this byte.
So far I have not been able to code an expression that will test this value. I have tried:
| Code: |
DECLARE msgAction REFERENCE TO InputRoot.MQRFH2.usr.ACTION;
IF (msgAction = '1')
...... |
but this does not work. The value of the byte (when = 1) is seen as by the broker.
Can anyone help?
Thanks,

I dont have exact answer but I do have idea to solve it .. 
Put the trace node and get the complete trace .. may be ${Root}
That will give the exact tree structure and hierarchy; use this in the ESQL and try again.
cheers

| Try Casting to a CHARACTER, and see if that helps. |

Why?
That would eliminate the benefits of using a reference.

Thanks for trying to help guys.
I had already tried the casting but it also failed. I was kinda hoping the broker would perform an implicit cast for me. Unfortunately not.
I have now redesigned how I am putting the value into the RFH2 header so that the broker now sees it as a 1.
Thanks again,
