Critical problem with retrieving Categories

I'm working on a service which calls the LiveLink webservices (EWS) and until yesterday, the getCategoryTemplate method of the DocMan service worked. When my code calls that method with a valid ID for a category, i receive a message which says "An unknown error occurred."

The Log from the EWS is the following:

2010-10-12 13:46:08,9415 WARN [13] Livelink error occurred
2010-10-12 13:46:08,9415 WARN [13]   Status: 903101
2010-10-12 13:46:08,9415 WARN [13]   Error Code: DocMan.ErrorGettingAttributeGroupTemplate
2010-10-12 13:46:08,9415 WARN [13]   Error Message: An unknown error occurred.
2010-10-12 13:46:08,9415 WARN [13]   ApiError:

Could there be anything that has changed in the database which can be the source of this error? It doesn't seem like there's anyone who have changed anything.

Thanks

Hi, André.

Can you provide details about the category that you're trying to retrieve, please?

Thanks,

What information about the category do you need?

There had been a small change in the database. I was informed that the loginname collation was set to caseinsensitive. Could this have been the reason why i got this error?

The getCategoryTemplate was working fine until yesterday and my service-reference code was generated on my vm-machine(with an installation of LiveLink and EWS). I finally (after a workaround) managed to create new service-references towards the test-environment(not my vm-machine) and the getCategoryTemplate was working fine again.

Hi, Andre.

Does GetCategoryTemplate not work with any categories or only one in particular? Are the categories you're using on your VM and the test instance the same?

Can you provide details about the attributes in the category, particularly the types?

Thanks,

Scott

The really weird part is that i've created the service references by using the address to our test environment now. When i created a small consoleapplication and called the getCategoryTemplate method, it worked. I removed all the service-references + automatically generated code + configuration for the documentmanagement service, and when i re-referenced it by using the same address as in the consoleapplication, i still got the error/exception. How is this possible? There's nothing that has changed in the categories.

I don't think that the problem only has to do with the database. I created 2 small projects yesterday. One which was a console-application. And when i saw that i managed to get the category in that project, I tried to create a small WCF-service using webHttpBinding and that worked. So what I did yesterday, was to copy all my code into a new project and today i created the service references in that project, but for some strange reason it still didn't work.

Hi, André.

Are you getting the same error each time? Are you using the same category or does the problem happen with multiple categories? What attribute types are in the categories?

Thanks,

We have it working again. I'm not 100% sure, but the problem seemed to be that someone where doing something with the groupaccesses at the time and somehow perhaps IIS stored somekind of configuration or something that made the problem persist for a while or something like that.

But i have another problem, will add it to a new post.
