Hi:
I am new to the message sets, and am trying to generate the following output record:
HEADER
RECORD1
RECORD2
RECORD3
RECORD4
RECORD4
RECORD3
RECORD4
RECORD5
END
The records are fixed length. Record 4 could occur multiple times after RECORD3. RECORD3 itself is not repetitive. But the combination for RECORD3 and RECORD4 is.
I am using TDS wire format.
I created a complex type, called DETAILS and configured it to have min occurs as 1 and max occurs as -1. I made RECORD3 and RECORD4 are elements under this complex type. With this set up, I get the following:
....
RECORD3
RECORD4
RECORD3
RECORD4
...
I tried defining another complex type (ITEMS) and made RECORD4 its element and configured ITEMS to have max occurs as -1 with no luck.
Would using DFDL have made it easier?
Please help. |

Yes, probably. Also faster and more flexible and subject to future enhancements.
If you want to stick with your TDS model, you will need to make RECORD4 a *child* of RECORD3, not a peer. |

Thanks for such a quick reply!
I remember trying it too.. might not have used right configurations/combinations ...but will try it again...
Can RECORD4 be configured to have max occurs as -1 OR should I create ITEMS after the last child of RECROD3 and have ITEMS have max occurs as '-1'? |

You should have a structure like
| Code: |
MESSAGE
HEADER
RECORD1
RECORD2
RECORD3 -(repeats as many times as allowed)
RECORD4 -(repeats as many times as allowed)
RECORD5
END |
And you need to make sure that the parser can distinguish record1 from record2, and more importantly it can distinguish the last RECORD4 before the next RECORD3, and likewise from RECORD5.
Hopefully, if you are using TDS, then each HEADER, RECORD, and END start with a tag. |

I think you need to use a sequence group for this:
| Code: |
Message
Record1
Record2
sequence group maxOccurs=unbounded
Record3 maxOccurs=1
Record4 maxOccurs=unbounded |
You could do the same in DFDL, but you would need to replace the sequence group with an element ( because DFDL does not allow a sequence group to have maxOccurs >1 )

Now I build the following structure
HDR
RECORD1
RECORD2
ORDERS (sequence group, min 1, max occurs = -1)
RECORD3 (max occurs 1)
RECORD4 (max occurs -1)
END
I have the following code to populate
while (...)
SET OutputRoot.MRM.MESSAGE.ORDES[Ix].RECORD3.FIELD1 ='AA';
...
SET OutputRoot.MRM.MESSAGE.ORDES[Ix].RECORD4[Iy].FIELD1 ='BB';
...
with one record, it works fine. However, with two records it throws :

a few points
1)Why are you using the MRM Parser on Output? did you not heed the advice given and that the whole thing would be easier using DFDL?
2) the error seems to indicate that there aren't the number of elements in the tree that you think there are.
This post http://www.mqseries.net/phpBB2/viewtopic.php?t=70105 may give you some hints of traversing and extracting a number of elements from a tree with a variable size.
3) have you put a trace node before the compute node and examined the output to see if the tree is actually has the structure you think it has?
4) a lot of useful information can be gleaned from looking at the UserTrace output that may not be visible when using the debugger. Give it a try and add this tool to your library.

Thank you mqjeff, smdavies99 and kimbert for your advise.
I got it working now.
smdavies99: When I started reading about the message sets stuff, I got cwf and TDS and the documentation said for CBL, it is recommended to use TDS. I had all the records defined and got the stuff working and this new additional requirement (to have repetitive RECORD4) got me retouch the code. For another message flow,I had DFDL parser. Thanks again for your advise.
The exception was a mistake on the code side and it was fixed.
Thanks again guys! |

I thought the error code had made that clear: Array subscript error...
