Florian Müller commented on CMIS-504:
-------------------------------------
The getChildren section (2.2.3.1) states for the filter parameter:
"String filter: See section 2.2.1.2.1 Properties. The service will only
return the properties in the matched object if they exist on the matched object
type definition and in the filter."
Therefore, it seems to be valid to set this filter.
The current CMIS 1.1 draft (which admittedly isn't an approved specification,
yet) clarifies this topic even further. It states in section 2.2.1.2.1
Properties:
"Unknown query names or query names that are not defined for the object-type
SHOULD be ignored. For example, if getChildren is called with a filter that
contains the property cmis:contentStreamMimeType, it SHOULD return all
non-document objects without this property and SHOULD NOT return an error."
So, even if the CMIS 1.0 specification is consider unclear in this regard, for
the sake of forward compatibility a repository should ignore properties that
are not defined in the object-type.

> Issue Type: Bug
> Components: opencmis-workbench
> Affects Versions: OpenCMIS 0.6.0
> Reporter: Nikola Soljaga
>
> When asking for children, workbench sets filters that are document specific,
> like: "cmis:contentStreamLength", "cmis:contentStreamMimeType",
> "cmis:contentStreamFileName".
> Specification says next for filters:
> >>>>
> 2.2.1.2.1 Properties
> ...
> Optional Input Parameter:
> String filter: Value indicating which properties for Objects MUST be
> returned. Values are:
> ...
> A comma-delimited list of property definition Query Names: The properties
> listed MUST be returned.
> >>>>>
> For children that are folders there are no content specific properties (like
> "cmis:contentStreamLength" for ex.). Workbench shouldn't set document
> specific properties while calling getChildren() service because those can't
> be returned for children of folder type.
