Re: [bpel-dev] ExtensionActivity Deserializer problem

[Tobias Liefke <tobias.liefke@xxxxxxxxxxxxx>]

Hi Hasitha,

 

I will try to answer instead of Bob.

 

The problem is not your Serializer/Deserializer, but your implementation of ExtensionActivity (PeopleActivityRTImpl?). Without knowing that class I can only guess, that you are using this.getElement() in PeopleActivityRTImpl.basicSetRemoteTask(RemoteTask rt) to add the the element of the remote task. This will add the RemoteTask element to the <bpel:extensionActivity> element, as this is the one which is connected to an implementation of ExtensionActivity.

 

You can find a working example of an ExtensionActivity in the SMILA project (http://www.eclipse.org/smila/):

https://dev.eclipse.org/svnroot/rt/org.eclipse.smila/trunk/tooling/org.eclipse.smila.processing.designer.model/code/src/org/eclipse/smila/processing/designer/model/processor/util

 

Finally some remarks on HTDeserializer:

1. A serializer/deserializer must be stateless (your instance variables may lead to unexpected side effects).
2. XML is case sensitive. Don't use equalsIgnoreCase when comparing the element name.
3. Why are you iterating twice over the list of child nodes?

Hope that helps,

Tobias

Betreff: [bpel-dev] ExtensionActivity Deserializer problem

Hi Bob,

I am trying to implement an extensionActivity . This activity generates following XML code.

<bpel:extensionActivity>

<b4p:peopleActivity name="PeopleActivityRT">

<b4p:remoteTask></b4p:remoteTask>

</b4p:peopleActivity>

</bpel:extensionActivity>

But I have found an error when I open a saved bpel file using business process editor. When I open a bpel file using business process editor, it changes like this,

<bpel:extensionActivity>

<b4p:peopleActivity name="PeopleActivityRT">

</b4p:peopleActivity>

<b4p:remoteTask></b4p:remoteTask>

</bpel:extensionActivity>

This is not happened when I open a file using XML editor. So I thing it is a problem of Deserilizer of the extensionActivity. Any Idea about what went wrong ?.

I have attached Deserializer and Serializer classes.
