Symptoms

Errors intermittently surface about compiling the proxy code for a WCF EndPoint Assembly broker. This seems to occur whenever the K2 Service is restarted. Sometimes we get the error in SmartForms and other times the DDLs loaded from the web service (async) just have the green spinner go away and no rows ever loaded. Doing a CTRL F5 refresh of the form loads the proper values on the next call.

In the windows App log in event viewer we see

Event IDs 10702 (3 - 4 instance for 2 calls one method on two different Services)
10702 An error occurred in the MYSERVICEINSTANCE]. There was an error in compiling the proxy code.
10702 An error occurred in the MYSERVICEINSTANCE]. Could not find file 'C:Usersmscomk2dAppDataLocalTempLocHub-Order'.
10702 An error occurred in the MYSERVICEINSTANCE]. There was an error in compiling the proxy code.


 

Diagnoses

I went through the log files and narrowed down the error. This looks to be an issue that needs a coldfix from labs.
 

Resolution

Labs provided a coldfix for the use of the resources with the WCF calls. After applying them, the load was successful.
