Appointment Script Error on Save Event: Mscrm.Form_onsave is not a function at eval

Posted on by yleclerc 1,549

We are getting a very weird error on the Save event on Appointment Form.

We have no script on the form.

But every time we hit the Save Button, we get this error:

TypeError: Mscrm.Form_onsave is not a function at eval...

    Yvan,

    I believe your instance was upgraded from earlier version. If you want to do everything supported way you should just recreate appointment form from a scratch (not using Save form as) and deactivate current one. If you're lazy (like me you can use following approach):

    1. Create solution with appointment form you have issues with only.

    2. Create new appointment form in this solution.

    3. Export solution and unpack it, open customizations.xml file.

    4. Look for <event name="onsave"... tag in it. For your old form it should contain <Handler functionName="Mscrm.Form_onsave"... tag or something similar - that will be setting that causes issue you experience.

    5. Look for the second <event name="onsave" ... tag - it should contain onsave handler as well but in updated version of CRM. Copy content of functionName to your handler from step 4.

    6. Save file and put it back to solution.

    7. Import solution to CRM.

    Hi Andrew, Thanks so much, one more time!

    As you may know, we can not create new forms nor use the "Save as" button on the Appointment entity (Probably for Outlook integration purposes), but you still got me on the right track.

    What I ended up doing:

    1. Create a solution with problematic appointment form in it
    2. Export, unpack, and open the customization.xml file
    3. Remove entirely this tag
      <InternalHandlers>
      <Handler functionName="Mscrm.Form_onsave" libraryName="Appointment_main_system_library.js" handlerUniqueId="bd8e0272-4f6c-42e6-a51e-71e0fc627a5f" enabled="true" passExecutionContext="true" />
      </InternalHandlers>
    4. Save, Zip, Reimport

    And Boom, the problem is gone.

    Note: our instance was, indeed upgraded from another version. The weird thing is we only have this problem 1 one organization. Other 3 organizations did not have this problem.
