Richfaces 4.3.5.Final ajax calls broke with JSF2.1.28 ------------------------------------------------------ Key: RF-13598 URL: https://issues.jboss.org/browse/RF-13598 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: compatibility Affects Versions: 4.2.3.Final, 4.3.5 Environment: Tomcat 7.0.50, Richfaces 4.3.5.Final, JSF 2.1.28, client side: IE8+ Reporter: Wang Liyu Assignee: Brian Leathem Priority: Critical Fix For: 4.3.7 Original Estimate: 4 hours Remaining Estimate: 4 hours I recently tried to update the JSF to 2.1.28 with using Richfaces 4.2.3.Final or Richfaces 4.3.5.Final, and I had issue with AJAX calls. not sure if this is Richfaces issue or JSF issue. My setup is JSF2.1.28, Richfaces 4.2.3.Final (or 4.3.5.Final), WELD 2.1.2.Final, Tomcat 7.0.50, on the client is IE browser. The ajax call will stuck, I looked into the JSF.js, seems it added new method from 2.1.28, {code} var getEncodedUrlElement = function getEncodedUrlElement(form) { var encodedUrlElement = form['javax.faces.encodedURL']; if (encodedUrlElement) { return encodedUrlElement; } else { var formElements = form.elements; for (var i = 0, length = formElements.length; i < length; i++) { var formElement = formElements[i]; if (formElement.name.indexOf('javax.faces.encodedURL') >= 0) { return formElement; } } } return undefined; }; {code} In IE, form['javax.faces.encodedURL'] is undefined, and the " if (formElement.name.indexOf('javax.faces.encodedURL') >= 0) {" will throw exception before it return. this cause the Browser miss behavior, Just wondering is there anybody has the same issue or is Richface 4.x support this version of JSF?
