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:

protected override void PerformFlush(IDesignerSerializationManager manager)

{

IDesignerHost host = (IDesignerHost)GetService(typeof(IDesignerHost));

Activity rootActivity = host.RootComponent as Activity;

if (host != null && host.RootComponent != null)

{

if (rootActivity != null)

{

XmlTextWriter xmlWriter = new XmlTextWriter(this.xoml, Encoding.Default);

try

{

WorkflowMarkupSerializer xomlSerializer = new WorkflowMarkupSerializer();

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.

John - can I ask why it matters The namespace prefixes are arbitrary and dont really matter in terms of what they are.

When I save the xoml via the Re-hosting the Workflow Designer example, I get xoml that is content different (all the public properties are listed in the root node and the namespace aliases are wrong) from the xoml that I loaded into the designer. It may not make a functional difference, but if I choose to add the WFPad xoml option to this Re-hosting designer, the user is going to be surprised to see the xoml change after clicking the save button (even if they did not do anything).

Sincerely,

John Portnov

Well - my first response is that anyone who can edit xoml by hand will know that the namespace prefixes aren't important ;-)

But - I *believe* (but have not tried it) you can accomplish your goal by creating your own WorflowMarkupSerializerManager (specifically the GetXmlQualifiedName method is the one you want to override).

Jon,

Thanks. Can you offer any code samples on how to do this

Sincerely,

John Portnov
