Creating workspaces at runtime

[jpalka]

Hi,

I have a question about creating workspaces in Modeshape 3beta3. I have set "allowCreation" to true in configRepository.json and have used following code snippet to create workspaces at runtime:

{code}

		Session defaultSession = repository.login("default");
		Workspace defaultWorkspace = defaultSession.getWorkspace();
		defaultWorkspace.createWorkspace("ships");
		defaultSession.save();
		defaultSession.logout();

{code}

What happens is when I run my example with this snippet commented out I got:

Exception in thread "main" javax.jcr.NoSuchWorkspaceException: The workspace ships was not found

    at org.modeshape.jcr.JcrRepository.login(JcrRepository.java:667)

    at org.modeshape.jcr.JcrRepository.login(JcrRepository.java:578)

    at org.modeshape.jcr.JcrRepository.login(JcrRepository.java:147)

    at org.modeshape.jcr.client.App.main(App.java:47)

What is more interesting when I add content to "ships" workspace the content is persisted, but I have to create workspace every time between restarts. What's worse worspaces at runtime ar not visible from WebDAV server. One of requirment for my case is that I will create workspaces at runtime and they content of the workspace will be visible for other systems through WebDAV.

I checked JCR spec and it doesn't say anything interesting about createWorkspace method. Is there any way I can work around it?

Jarek

Hi Jarek,

This seems like a bug and I've logged https://issues.jboss.org/browse/MODE-1617 for it. Btw, creating workspaces does not require a session.save() call, as the operation is considered a "workspace operation".

Hi Jarek,

this error plagued me also. It took me till yesterday till I could pin it down as it happened a bit weirder to me. An way around your problem for the moment would be to create 1 more workspace at runtime than you need, as it seems if you create 1, you get 0, if you create 2 workspaces you get 1 (the first one created), with 3 you get the 2 first created ones  and so on....

Hope this is fixed soon,

Best

Can I tweet about this? Or perhaps might there be a blog about it?
