error when i edit claim rule

Question

Hi, I configure and add a custom Attribute Store with MySQL but when i edit claim rule with:
=> issue(store = "MySql", types = ("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/estado"), query = "name={0};estado", param = "Idoya");
I have a error:

"The Federation Service encountered a serious error while processing the WS-Trust request.
Request type: http://schemas.xmlsoap.org/ws/2005/02/trust/RST/Issue
Additional Data
Exception details:
System.NullReferenceException: Object reference not set to an instance of an object.

Please help me!
Thanks

Hi
  From your post, I understand that you have implemented a custom attribute store? In that case, you may want to begin by debugging your custom attribute store code as most likely the error is thrown from there.

More information on implementing custom attribute store can be found at

You can also look at the event log and see if any other error is logged + turn on tracing (by turning on the trace settings in Microsoft.Identityserver.servicehost.exe.config file and see where the exact failure occurs). Tracing will not show errors in your attribute store implementation but might point to any problems when the issuance pipeline tries to process the query using your attribute store..

Also, please note that there is a built-in SQL attribute store that you can use to talk to any SQL Database store if all you want to do is pass in a SQL query to issue claims. If it does not satisfy your requirements, you may choose to implement your own attribute store.

Also, you may want to take a look at for claims rule language specifics including samples..  http://technet.microsoft.com/en-us/library/dd807118(WS.10).aspx

Hope this helps.
