Attributes search correction (TANGOARCH-760, PROBLEM-1823)
Did some changes for jira tickets TANGOARCH-760 and PROBLEM-1823: With these changes, all attributes search work the same way:
- They are non blocking and they display a waiting popup during the search
- The search can be cancelled by closing the popup
- The search field and button are deactivated during the search
- The search can be started both through Match button and by pressing [Enter] in text field
Also avoided some undesired error traces, by avoiding the refreshment of undisplayed panels
