Hi Kjanicki,


 


Do you recieve this error when opening K2 Designer or when creating/editing a form/view? Also could you tell me what version of K2 Blackpearl and Smartforms you are running?


 


Kind  regards,


Yannick

Hi kjanicki!

 

To add onto Yannick's questions, have you performed an IIS reset yet to see if that will fix it? Also, are you able to browse to the K2 Designer from the K2 server? 

 

A previous client had a similar problem that was fixed from clearing the browse cache in IE so that may be an option you'd like to try as well.

 

Regards,

Alyssa

 

If you are on SF 1.0.6 and k2 4.6.7; there is a hotfix that can be supplied by penning a ticket

I have seen this error several times and it usually happens when there is a rule where the reference to a smartobject has been changed or is no longer mapped correctly.

 

If you get this when opening a form start digging through the initialize rule to see which smartobjects the form is reading. Most likely this is the cause. If you get the error when submitting then check you create or update methods for that button. 

 

I have also seen this error on Package and Deploy. This is usually do to a minor difference in the SQL references from the environment it was packaged from to the environment it is being deployed to. If this happens to be the case you will need to make sure your SQL tables match one for one. If they do match then try refreshing the service instance.

 

Thanks,

Bryan Peters
