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.

      You mean you can submit the form now? Have you enabled any debug logs?

      Can you please share the form's package and its dependencies, if any, so that I can test it at my end? Are all the OSGi bundles active?
