Why "Uncaught RangeError: Maximum call stack size exceeded" error occurs?Issue User had configured a UI Action, which in turn opens the UI page as modal window. The UI Page's client script was making call to method defined in UI Action, this call was happening when the user clicks on "Ok" button on the modal window, during that time, following error stack appeared in the browser console and function didn't get call. js_includes_doctype.jsx?v=02-26-2018_1106&lp=Thu_May_24_07_14_52_PDT_2018&c=16_258:534 Uncaught RangeError: Maximum call stack size exceededat gel (js_includes_doctype.jsx?v=02-26-2018_1106&lp=Thu_May_24_07_14_52_PDT_2018&c=16_258:534)at closeProject (eval at evalScript (js_includes_doctype.jsx?v=02-26-2018_1106&lp=Thu_May_24_07_14_52_PDT_2018&c=16_258:84), <anonymous>:3:19)...ReleaseAny releaseCauseA method was defined with the same name in UI Action and UI Page, and hence when it was invoked from UI Page, instead of invoking the definition in UI Action, it was invoking the definition in UI Page, which in-turn calls again the same method in UI Page, finally it went on an infinite loop until maximum call stack size exceeded.ResolutionMake sure the method in UI Action has different unique name than in UI Page.Related LinksUI actionsUI Pages
