Exception when filtering data of entity which contains transformable attribute about coredatautility

[yepher]

Do you have a sample .mom and persistence file that demonstrates this?

It's reproducible in test file 'fetchRequest.mom': just try to filter AnotherEntity

Thanks, I was able to reproduce this. I will have a look at it.

Filter no longer crashes on entities that contains NSTransformableAttributeType.

@garnett can you please verify it is working for you. If so I will close the issue.

This is the commit that solves the issue and has been merged into Develop and Master. I will wait until verified before merging into feature/multiDocSupport.

Prevents crash when attribute type NSTransformableAttributeType. This was reported in issue #14.

On a side note:

I don't really call this a fix. It is more of a solution to prevent the filter crash.

I would like to enable filtering for this type somehow but I am not sure what the best solution is. The attributeValueClassName will probably help with the filter scheme but I am not sure how folks tend to use this in their data models. If it is custom classes than maybe the best we can do is allow them to filter by size or less valuable "attributeValueClassName" which will probably be all the same.

For now I have just excluded "NSTransformableAttributeType" from the filter list until someone finds a need and can offer a good scenario for filtering by that attribute type.

Works for me.
