Andrea Ligios commented on CMIS-1117:
-------------------------------------
Thank you very much for your answer [~fmui] .
I didn't see your comment while I was editing the question, I've changed it to
bug before reading it, but it seems there's nothing that can be done on your
side, so please tell me what type should I set for this one.
I'm going to add the check in front of the call now, but this could potentially
help others in the future, so I'd like to leave it neat

> I have a test case that is trying to create a document by passing the
> _*"cmis:folder"*_ ObjectTypeId (instead of _*"cmis:document"*_), and expects
> the test to fail.
> * With *Browser binding*, {color:#00875a}it fails with a
> CmisConstraintException{color}
> * With *WebService binding*, {color:#00875a}it fails with a
> CmisConstraintException{color}
> * With *AtomPub binding*,{color:#de350b} it creates a Folder, and then fails
> later with a CmisRuntimeException{color}
> While debugging the code, I've seen that *Browser binding* (along with
> *WebService binding*) has a *_createDocument()_* method in its [ObjectService
> implementation|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-server/chemistry-opencmis-server-bindings/src/main/java/org/apache/chemistry/opencmis/server/impl/browser/ObjectService.java#L88-L137]:

> The *AtomPub Binding*, instead, has a _*create()*_ method in its
> [ObjectService
> implementation|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-server/chemistry-opencmis-server-bindings/src/main/java/org/apache/chemistry/opencmis/server/impl/atompub/ObjectService.java#L79-L158]:

> While the _*createDocument()*_ method allows us to check if the ObjectTypeId
> passed is the proper one (*_"cmis:document"_*), and to raise an error if an
> unexpected ObjectTypeId is passed, the _*create()*_ method is agnostic about
> the object to create, and forces us to perform a Switch on the ObjectTypeId
> to detect the proper action to call.
> Hence, calling _*createDocument()*_ with *AtomPub binding* and
> _*"cmis:folder"*_ ObjectTypeId will result in calling the _*create()*_
> method, and then in the switch reading _*"cmis:folder"*_ and calling the
> underlying _*createFolder()*_ method, instead of the underlying
> _*createDocument()*_ one.
> The folder will be created, then somewhere up in the chain[*] the error will
> be detected and will trigger a *CmisRuntimeException*, but that implies that,
> * for the same call, two different exceptions could be returned depending on
> the binding used
> * for the same call, the AtomPub binding will create an unwanted object
> before returning an error
> Could you please confirm me this is intended, and maybe shed some light on
> why the *AtomPub binding* is working with a different set of creational
> methods than the other bindings?
> Should we simply add a check in front of the calls to cover cases like this?
> [*] It's the [FolderImpl
> class|https://github.com/apache/chemistry-opencmis/blob/trunk/chemistry-opencmis-client/chemistry-opencmis-client-impl/src/main/java/org/apache/chemistry/opencmis/client/runtime/FolderImpl.java#L83-L103]
> that checks that the object created is of the expected type, and this seems
> an attempt to cope with the problem... but one that leaves debris behind,
> though (the folder created):
