Vihang's Re-hosting Workflow Designer example Serialization problem
Vihang,
I have downloaded the code for Re-hosting the Workflow Designer and have commented out the part that recompiles the code behind (I just need to update and save the xoml for now).
The problem is that the namespace aliases get reversed when the following code executes:
protectedoverridevoid PerformFlush(IDesignerSerializationManager manager){
IDesignerHost host = (IDesignerHost)GetService(typeof(IDesignerHost));Activity rootActivity = host.RootComponentasActivity;if (host !=null && host.RootComponent !=null){
if (rootActivity !=null){
XmlTextWriter xmlWriter =newXmlTextWriter(this.xoml,Encoding.Default);try{
WorkflowMarkupSerializer xomlSerializer =newWorkflowMarkupSerializer();xomlSerializer.Serialize(xmlWriter, rootActivity);
}
finally{
xmlWriter.Close();
}
}
}
--
If I load the following xoml (in Fig 1-1) and click the Save button (without making any changes), my output xoml (in Fig 1-2) will have different namespace aliases because the bolded code above executed.

Why are the namespace aliases for BagTagActivity and ADPSendEmail activity reversed? (the namespace aliases are bolded above)
I look forward to your reply. Thanks in advance.
Sincerely,
John Portnov
