sData HTTP 500 Error - Out-of-the-box

Greetings,

 

I have a strange error with sData throwing an HTTP 500 error when accessing the Opportunities resource.  This is occurring out-of-the-box with the demo database and has been reproduced by an associate on a completely different server.  The problem isn't that it's a 500 error, the problem is that it's doing something that it shouldn't (I think).  But, first, the calling command and the part of the error that is confusing (the whole error is below):

 

http://actforweb.bpanet.de:8080/sdata/slx/dynamic/-/opportunities


No row with the given identifier exists[Sage.SalesLogix.Entities.Account#AA2EK0014415]

 

This is particularly strange, as the account does in fact exist but should not be shown for the logged in user (demodb:  derek).  If requesting the record directly from the accounts resource [../-/accounts('AA2EK0014415')] throws the proper HTTP 410 error meaning (resource gone, no forwarding address).

 

From my understanding, the 'opportunities' resource should be similar to that of 'contacts' or 'accounts', in that only the records for which the user has access should be displayed.  When I access the accounts resource for the derek user, I get a small subset of the total database.  With that in mind, I've tried to control the data being returned by using the 'include' command for the 'accounts' resource:

 

http://actforweb.bpanet.de:8080/sdata/slx/dynamic/-/accounts?include=opportunities

 

Theoretically this command should not bring back any accounts that the user should have no access to (if my theory of sData controlling the return by security rights is correct).  Instead, I get the same error.  It's simply the inclusion of 'opportunities' that has this issue.

 

Trying this for other user logins, I get similar results.  Some users with rights to all the records in the database (admin, lois, samantha) have no issues.  But, as soon as I log in as another user who recieves only a subset, I get an error.  And, it's not always for the same AccountId.  Furthermore, the integrity checker has been run and there are no outstanding errors.

 

To make things even more complicated, the about 1% of the time in my testing would it actually work.  Subsequent query, identical to the one that worked would fail.  And, I cannot make it work consistently in any way.  (Other resources also throw errors, but I'm not sure I understand how they should work for a non-admin, so I haven't tried to debug commonalities -- for example OwnerRights also errors with unknown row ...Security.Owner#ADMIN, or Processes for an unknown but existing contact).

 

The entire error is below:

 

SLX version 7.5.2.  Server:  Windows 2003.

 

Demo server is open, if anyone wants to take a look.  No passwords for admin and derek.  It's restored automatically every night, so feel free to do a little testing, if you have the time or inclination.

 

Thanks in advance!

Re: sData HTTP 500 Error - Out-of-the-box

Ok, I'm not sure how I missed this in the error message (eyes not open, maybe), but it's failing on the 'reseller' xml tag.  I looked in the two opportunity.cs files that were referenced and it's the 'reseller' that is somehow killing the feed.  This still doesn't make sense, as it returns the key of the reseller (an account), and the url in the complex tag, but it's not attempting to access any data from that account (perhaps sData has to verify the account's existence first?).

 

Normally the reseller is returned in this format:  

<slx:Reseller sdata:key="AA2EK0013627" sdata:uri="http://192.168.178.100:3333/sdata/slx/dynamic/-/accounts('AA2EK0013627')" sdata:uuid="00000000-0000-0000-0000-000000000000" />

If I could simply control the payload, then I could get rid of the 'reseller' tag.  But, that doesn't work.  the ?select= doesn't seem to work at all and doesn't present a subset of the data, only the entire entity.  And, there is no ?include!=reseller (not equal -- or something similar to tell it not to bring back the reseller tag).

 

Any ideas on how to limit the return value so that reseller isn't displayed?  (I don't need it anyway.)

 

Anyone....  Anyone....

Re: sData HTTP 500 Error - Out-of-the-box

Solution:  Upgrade to 7.5.3.  It must have been a known error with 7.5.2 (sData 1.0) that they fixed in the next version.  Next problem:  While they fixed Opportunities, they broke Activities with 7.5.3.  At least you can work around it by adding the ?exclude=enddate parameter (but that's still kind of bad).

 

Cheers.
