Invalid xml document for BPEL Process.

Question

Hi everyone,
I am getting below error after i set validateXML=strict
Invalid xml document.
According to the xml schemas, the xml document is invalid. The reason is: Error::cvc-datatype-valid.1.2.1: '' is not a valid value for 'decimal'.
Error::cvc-type.3.1.3: The value '' of element 'ns1:p_person_id' is not valid.
Please make sure that the xml document is valid against your schemas.
Kindly help me with the steps. I am just a SOA admin, not developer.
Regards
Lammeki.

Ummmm Vikas,
Lemme bring out a better picture, so u get more clear on this one.
The developer has upgraded an already deployed BPEL process.
Since then, she has been facing problem. When she invoke those process they simply end up as faulted with a yellow color ! mark.
Now i as an admin, i tried everything to help her cos she escalated the issue to me, thinking maybe there is sumthing i could do to assists her.
Now i am not sure, how to help her, but yes i started with the logs. Both the oc4j container log for SOA and the domain log show the similar error.
But till then, i didn't know black and white of it. so i tried doing all testing possible from my end.
When i check on the faulted instances i see there is a Assign activity after Transform followed by Invoked being highlighted in red color. and when i clicked on it i get to see the error
Assign_41

Please make sure the variable/expression result "/ns6:QueryPerAllPeopleOutputCollection/ns6:QueryPerAllPeopleOutput/ns6:EMPLOYEE_NUMBER" is not empty.
Possible reasons behind this problems are: some xml elements/attributes are optional or the xml data is invalid according to XML Schema.
To verify whether XML data received by a process is valid, user can turn on validateXML switch at the domain administration page.

The main problem was we were observing many SOA inactive threads in one particular database, and they keep building up minutes by minutes.
I suspect, that in the code connections were open but were not closed, there4 there were inactive threads in the database.
I had to stop the SOA application, to stop threads from building up. I guess they got build up when they were invoked. There is definitely some fault with the code. or tell me am wrong. tell me its sumthing else.
However other domains processes were working fine.
and oh, yes the developer also made changes in the database. when i asked her to revert back and see if it works, she say thats a huge amount of work.
Finally she end up saying that maybe it could be a problem with the new version.
Now as a learner, I want to know what is going on, and how do we go about solving it.
Am not much of a SOA techie. that u can make out. but yes ready to learn things. so there4 i beg you to explain to me like am a standard 3 or 4 kid. any more information needed plz feel free to write back.
