Unknown error in XPath - Invalid Xpath Syntax

Hello,

 

I am building an Adaptive form, and I noticed that I was getting some errors in the log when I render the form in the Workspace UI. I am getting this error on two different tables and two different check boxes. Despite the errors, the fields are displayed properly and the fields with rules and behaviors do what they are supposed to do. I tried deleting the fields and remaking them, but that didn't stop the errors from happening. Does anyone have any suggestions?

 

Here is an example of the error message:

In case anyone wants to know what happened here, this is the error message you receive when you have an adaptive form that uses an xsd schema and you add an unbound control to the form. You can either live with the error message, or bind it to an element in your schema.

@seanlapointe Are you able to submit the form in Workspace? If you are not facing any functional issue, then you may ignore this error.

Also, few points to check:

 

1. if you are on Unix, please make sure you have installed all the 32 bit libs, as per [0]. 

 

2. check if all the OSGi bundles are active.

3. try reinstalling the Forms add-on package and restart the instance.

    Thank you. My system is Windows based. The form has failed to submit a couple of times, but I think it might have been an unrelated bug that I have since fixed.

     

    Every form render in DEV adds about 20MB to the error log, so if I were to push this form to production, it would increase the log size by about 20GB a day. Is it safe or even wise to have logs that big? It has to be difficult to look through an error log that big to trouble shoot issues.

     

    If you are saying that I can signore these messages, does that mean you know what causes them? Can you provide any details? I would prefer to not have errors.

      Here are the instructions:

       

      1. Stop AEM Forms server.

      2. Take the back up of crx-repo.

      3. delete all the folders in crx-repo, except "install" folder.

      4. Start AEM Forms server.

      5. Wait until error.log get stabilized.

      6. check if all the bundles are active.

      7. Restart AEM Forms server

       

      Note: this will wipe out the Service pack(6.5.7) applied. You would need to apply it again, along with the Forms add-on package.


      I added the form to a different server and also added the relevant processes to workbench. When I render the form in the Workspace UI on this new server, I am still getting these error messages.
