Anthony O. created RF-12604: ------------------------------- Summary: "Uncaught TypeError: Cannot read property 'name' of null" when double clicking on a a4j:commandButton Key: RF-12604 URL: https://issues.jboss.org/browse/RF-12604 Project: RichFaces Issue Type: Bug Security Level: Public (Everyone can see) Components: component-a4j-core, component-input Affects Versions: 4.2.3.Final Environment: JBoss 7.1.1.Final Reporter: Anthony O. Priority: Blocker I've got a {{a4j:commandButton}} which {{render}} itself and is {{rendered}} if the number of time I've clicked on it is less than 1. The problem is that when I click twice on it very quickly, then I've got a "Uncaught TypeError: Cannot read property 'name' of null" from {{jsf.js.xhtml}} and then no more AJAX query can be sent from the UI (all the {{a4j:commandButton}} for example do nothing more), and the status is frozen to the {{start}} facet (my progress.gif is never hidden because neither {{onstop}} nor {{onerror}} methods are called). Here is the JS stack : {noformat} Uncaught TypeError: Cannot read property 'name' of null jsf.js.xhtml:1 request jsf.js.xhtml:1 richfaces.queue.submitFirstEntry richfaces-queue.js.xhtml:270 richfaces.queue.onComplete richfaces-queue.js.xhtml:248 sendEvent jsf.js.xhtml:1 response jsf.js.xhtml:1 richfaces.queue.response richfaces-queue.js.xhtml:413 jsf.ajax.response richfaces-queue.js.xhtml:50 onComplete jsf.js.xhtml:1 req.xmlReq.onreadystatechange jsf.js.xhtml:1 {noformat} I will attach test.xhtml & TestAction.java -- This message is automatically generated by JIRA.
