MQSeries.net :: View topic - Parsing multiple fixed length records in one MQ Message

Hi,

I am able to parse multiple tag delimited records in one MQSeries message (Thanks Jeff Lowrey for your pointers).'

'

Now I have to parse multiple fixed length records from a single MQSeries message.'

'

I end up with the infamous "MRM parsing error. Message bit stream larger than expected." message in the Windows Event Log.

The records I have to parse look like this:

Field1Field2Field3<LF>
Field1Field2Field3<LF>
Field1Field2Field3<LF>

If I add a Trace Node just after my MQInput Node, I can see that I'm able to parse a single fixed length record.
If I try to parse more than one record record, I get the above mentioned infamous message.

Here is how I tried to model the MRM message:
- Created a Message Set project with CWF.
- Created global elements: Field1, Field2, Field3
- Created Type Fixed1 with the following:
- Element reference to Field1, Field2, Field3

- Create a global element named elemFixed of type Fixed1
- Created a type Fixed2 containing elemFixed. Set the MaxOccurs to -1. Modified the repeat count with various non convincing results.
- Created a message msgFixed of type Fixed2.

Is CWF the right MRM parser for this task or is TDS (Fixed) better suited for this task?
If CWF is the right approach, can anybody give me clues on how to solve this problem?

Thanks

Robert
