Hi Shiela, I had noticed this as well when I had set Fields to Hide but had chosen the Save the Data feature. Rui, this the error as the Event viewer logged it.

I'm hiding a section with field rules. Backend validation is turned off and the rules say to ignore data when hidden. Yet I still get the message. I found last night that it was because of a calculation field in a table row. When the section is hidden, the calculation field requires that values be entered in 2 other fields in the row. When the section is displayed, the two fields are required fields, so values have to be entered. I had to add 0 as a default value to those fields to get this to work. Not what I want to do because it's extra mouse-clicks for submitters, but I tried several other formulas and they don't seem to recognize that a row exists and so cause a failure too.

The message displayed is:

'' cannot be used as a numeric value. [LFF1012-InvalidNumericValue]

I have js and css on the form, but I tried removing both to see if that was the issue. The form still wouldn't submit. However, there is an error in the console log: "Uncaught SyntaxError: Invalid or unexpected token   Submit: 66" When I click on that, it displays code that isn't mine:

Thanks for letting us know. When is Update 1 expected to be released, and what other fixes do you think it will include?

Any heads up would be appreciated because we've been fighting the 10.3/10.3.1 releases for the last 4 weeks, creating workarounds for showstopping issues like Workflow Service Tasks that never return, monitoring everything going through the system, re-routing forms that end up in the wrong user tasks for some reason, modifying virtually every field on each form and saving it back to its original configuration so the database would recognize all the settings, ...

We've spent a lot of time after the upgrade trying to keep our mission-critical processes alive and viable. I'm sure we're not the only customer in this boat!

The issue that calculations in tables are not getting ignored when the table is hidden, ignore data and fields are read-only has been fixed at Forms 10.3.1 Update 1, and you can download patch file at https://support.laserfiche.com/kb/1013963/list-of-changes-for-laserfiche-forms-10-3-1-update-1

Thanks!

Still waiting on a fix for this, in 10.4
