ContenData field causing strange behavior

Hi,

 

While retreiving the FeedItems for a particular user from java code  I came across a weird behaviour

I have 300 feedItem records for the mentioned userID

 

If I fire this query 'Select Id, ContentData from userProfileFeed with userID = 'xyz' ' I can see only 1 record returned

 

but If I remove the Contentdata field and fire the same query query I can see all 300 records

 

is this some bug ? Why does inclusion of Contendata field produce this behavior?

Any pointers would be of great help

 

As a workaround I have used queryMore to retrieve the records one by one but it slow and inefficient.

 

P.S

I have used both enterprise/partner wsdls and the open source wsc code and the same problem is seen.

Thanks

-Jimmy

queries that return binary data (such as contentData, or attachment or document body fields) return there results 1 row at a time due to payload size issues, and like any other query, if the results are larger than the batch size, you have to call queryMore to collect the rest of the results.
