Problem Generating Management Events from DOM Elements.

Hi All,

I'm having some trouble with converting WEF ManagementEvents to strings
and back and I wonder if anybody can point out where I'm going wrong.

Here's a section of a string representation of an event (created with
event.toString() )

<muws1:SourceComponent>
        <muws1:ComponentAddress>
            <wsa:EndpointReference
xmlns:wsa="http://www.w3.org/2005/08/addressing">
                <wsa:Address>http://localhost/my-resources/services/event-publisher</wsa:Address>
            </wsa:EndpointReference>
        </muws1:ComponentAddress>
        <muws1:ResourceId>MyresourceID</muws1:ResourceId>
    </muws1:SourceComponent>

If i then create a DOM element from this string and use

ManagementEvent event = new SimpleWefFactory().createEvent(domElement);

and print out that ManagementEvent I see:

<muws1:SourceComponent>
        <muws1:ComponentAddress>
            <muws1:ComponentAddress>
                <wsa:EndpointReference
                    xmlns:wsa="http://www.w3.org/2005/08/addressing"
xmlns:wsa="http://www.w3.org/2005/08/addressing">
                    <wsa:Address>http://localhost/my-resources/services/event-publisher</wsa:Address>
                </wsa:EndpointReference>
            </muws1:ComponentAddress>
        </muws1:ComponentAddress>
    </muws1:SourceComponent>


It has duplicated and nested the ComponentAddress (along with duplicate
namespace) and removed the ResourceID.

This is causing problems further down the line with multiple namespace
declarations etc. When i display the domElement everything looks fine too
so I'm wondering if there's something wrong with the SimpleWefFactory?

I must be doing something wrong? Is there a recommended way to serialize
and de-serialize ManagementEvents to strings?

Thanks very much!
Keith

regarding this and the other issue, I am trying to make a 2.2.1
release, probably within a month.  This issue too will require an
issue in Jira.

2.2.1 is aimed as a bug fix release only and should maintain backwards
compatibility, if the fix for this breaks backwards compatibility it
may have to be pushed till 2.3.0

cheers,
Chris

Hi,

I had the same issue. It is preventing us from adopting the muse project.
Can this be fixed quickly?

-thanks

I do notice this problem and posted it on

We need to investigate this issue further.
