Information messages displayed using "addInfoMessage" from a script include showing multiple times at the top of a form - Known Error

Information messages displayed using "addInfoMessage" from a script include showing multiple times at the top of a form Description Using an addInfoMessage to show an information message at the top of the form, shows up multiple times

Steps to Reproduce

Create a Script Include Name : jjTest Check " Client Callable " Script : var jjTest = Class.create(); jjTest.prototype = Object.extendsObject(AbstractAjaxProcessor, { popUpInfo: function(current){ gs.addInfoMessage("This is just a test. Carry on!") }, type: 'jjTest' } ); Save Create a UI Action Name : JJ Popup Table : sys_update_set Action name : jj_pop_up Check booleans: Show Update Client List v2 Compatible Form Button Onclick : run() Condition : new jjTest().popUpInfo(current) Script : new jjTest().popUpInfo(); Save Go to sys_update_set.list Open an existing record You will notice 2 or more pop-ups at the top of the screen Expected behavior: Only one message should show up on at the top of the screen

Actual behavior: Having multiple messages show up at the top of the screen

Workaround This is expected behavior and by design in all currently supported releases.

Recommendation : never add messages during a server-side script call that is being used in a condition. This an anti-pattern and not recommended. Condition processing should only be used to evaluate a final answer of true or false and nothing more.
