问题 I have problems with a form saving to a store. The form loads a record for editing a existing record, or is blank for a new record. Editing a existing record works fine.

问题 I understand that it is generally considered a "bad idea" to store JSON in a MySQL column due to the fact that it becomes difficult to maintain and is not easily searched, or otherwise queried.

I have a styling issue where the backgroundColor style attribute shows a red line for a very specific layout of containers within that component. The red color is
