Has anybody worked on a wrapper for the Slide API (that does not use webdav) in order to simplify it and make it look like a filesystem usage ?

Andrey,
Thanks for following up. Martin Kal�n posted the same solution back on Friday (thread called "Problem creating Objects"), but I did not have a chance to test it out yet. Reading his description, it appeared that his solution would work, and I am glad you came to the same conclusion. I also noticed the changes in the store method of StructureImpl, but I did not want to undo and modifications.
Thanks again for the help.
Ivan

Subject: RE: Errors when creating a new node
Hi, Ivan!
Well, I've got the same error and fortunately found an easy way to fix it. Here's the explanation if you're still interested.
First of all, the error that the system gives you isn't quite accurate. When Slide tries to create a new node it calls the following methods of the org.apache.slide.structure.StructureImpl class:
public void create(SlideToken token, ObjectNode object,String strUri) public void store(SlideToken token, ObjectNode object) protected void store(SlideToken token, ObjectNode object, boolean setModificationDate)
and the last one tries to check if the active user has the appropriate access rights (write, in fact) to the object that is being created. So it calls the method
public void checkCredentials(SlideToken token, ObjectNode object, ActionNode action)
of the org.apache.slide.security.SecurityImpl class which, in turn, tries to find the object:
ObjectNode realObject = objectUri.getStore().retrieveObject(objectUri);
And this very call failed for me throwing up the ObjectNotFoundException. This exception is caught in the same method, swallowed and the familiar AccessDeniedException is thrown instead. Imho, it's a wrong way of handling this exception, it should be at least logged.
And now about the reason of having this ObjectNotFoundException. It's actually quite simple. The SlideToken I was using didn't have its store enlistment flag mutator set to true. As a result the retrieveObject method failed to find the object - the "creation" transaction hadn't been committed at that moment. So I just set this flag to true:
slideToken.setForceStoreEnlistment(true);
and the problem was solved. I hope it'll work for you as well. And why did it worked in the 2.0 release? I have noticed certain changes in the store method in the org.apache.slide.structure.StructureImpl class that might have caused this error but I haven't looked into them.
Yours sincerely, Andrey.
