Problem with Switch in BPM

[Former Member]

Hi,

I am running into a scnerio in which the Xpath condition in Switch Condition does not take effect correctly.

Basically I want if there is more than 1 Header items then go to branch 1 ELSE go to branch 2.

Xpath: (RFC_Response./p1:ZOTCI002_RFC_CAPITAL_RETURNS.Response/I_ZOTC_ORDER_HEADER/item[2] EX

But I get this Message and by default everything goes into my default branch.

"Multiple condition merges in default branch".

But when I try the same xpath in XML Spy for the given xml message it processes correctly so something is wrong with the Condition Editor in BPM.

I have tried the "count" xpath i.e

count(RFC_Response./p1:ZOTCI002_RFC_CAPITAL_RETURNS.Response/I_ZOTC_ORDER_HEADER/item) = 1

and I tried it to check if it is 1 or not but that does not work too.

Can someone tell me what is the problem??

Thanks

Hi,

one of the solutions you can try is to create a "dummy" abstract message with one field, then map your ZOTCI002_RFC_CAPITAL_RETURNS to this dummy one (transformation step) with a graphical mapping for instance - something like count all items - dummy-filed1

and then base your switch on the dummy message

we had lots of problems with the switch condition too

Hi Machal,

Can you please tell me how do I populate the "count" to a dummy message? Do i have to write some code in a java mpa to do this?

Thanks

Ya, you can't use the count function in XPATH - you can only use the functions given to you (EQ, etc etc). That bottom area is not a true free-form XPATH area.

In your mapping, do a custom user function into a "dummy" field in your layout to store the count... then set that up as a context object & you can use it inside BPM for your branching criteria.

The only other suggestion I have (although this never worked quite as we expected) is to use the XPATH "exists" and try to get it to reference the second line - if it comes back "true" take your branch. We prefered the 1st option, as it's a bit cleaner.

Hi,

you can do a very simple "advanced java function"

with one inbound argument

the source code (let's name it "easyCount"):

String s = String.valueOf(a.length);

result.addValue(s);

now in the mapping for the filed in the dummy interface

should look like this:

ZOTCI002_RFC_CAPITAL_RETURNS.Response/I_ZOTC_ORDER_HEADER/item -> removeContext(function from the Node functions) -> easyCount -> dummnyfiled

check it now the dummy field has the number of the items at least it should and now you can base your switch on this dummy field
