While navigating through panel form fields with tab key, all validations of the page are thrown as if a full submit was performed.
This happens when you have input list of value field and the focus is on the field and you press tab key. The input list of value is autosubmit in order to refresh other fields
In the test case run testTab page and press CreateInsert button. Click on Department or Job List of value field and press Tab key. All validations of the page appear.
I also notice that errors appear in Greek even though my browser language is in English.
