[richfaces-issues] [JBoss JIRA] Commented: (RF-4458) a4j:commandButton disabled attribute is checked prematurely

Thu Sep 11 16:48:20 EDT 2008

    [ https://jira.jboss.org/jira/browse/RF-4458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12429204#action_12429204 ] 

Shadow Creeper commented on RF-4458:
------------------------------------

Also, as a side note, the MyFaces <h:commandButton> does work as expected (just replace a4j:commandButton above with h:commandButton to test).

Thanks.

>             Project: RichFaces
>          Issue Type: Bug
>    Affects Versions: 3.2.2
>         Environment: Tested on JBoss 4.0.5 with Facelets 1.1.14, MyFaces 1.2.3 and RichFaces 3.2.2.GA
> Browsers tested Firefox 3.0.1 and IE 7(.0.5730.13)
>            Reporter: Shadow Creeper

> If disabled was true, the expected behavior (not allowed to click on disabled element) is seen.
> If disabled was false, the EL will be rechecked after click but before actionListener is run.
> Expected behavior:
> If disabled was false, then the button should work without checking disabled EL unless and until the button is told to reRender.
