return value
[ https://issues.apache.org/jira/browse/ODE-260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexey Ousov updated ODE-260:
-----------------------------
Attachment: ODE-260.patch
Here is how I fixed it (regarding to 1.1 branch). It is rather tricky, but I tried to touch as little parts of ODE project as possible.

> Very strange things happen, when executing exetrnal services in two-way style, and this service doesn't return values. Something like this:
> <?xml version='1.0' encoding='utf-8'?>
> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing">
> <soapenv:Header>
> <wsa:Action>http://www.comped.it/te/dbService/dbService/commitTransactionResponse</wsa:Action>
> <wsa:RelatesTo>uuid:hqejbhcnphr35voswr4cg3</wsa:RelatesTo>
> </soapenv:Header>
> <soapenv:Body />
> </soapenv:Envelope>
> First of all I got the following exception (happens only if INFO logging is enabled):
