[richfaces-issues] [JBoss JIRA] (RF-13018) a4j:commandButton wrong actions performed

[Robin Pradel (JIRA)]

    [ https://issues.jboss.org/browse/RF-13018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12972281#comment-12972281 ] 

Robin Pradel commented on RF-13018:
-----------------------------------

I can confirm the NPE. When clicking on {{h:commandButton}} beside a {{a4j:commandButton}} it leads to a NPE because {{String source = paramMap.get(SOURCE_ID);}} is {{null}}.

> When an a4j commponent (a4j:commandButton, a4j:jsFunction) is activated, actions of other a4j:commandButtons on the page with type=button will be fired.
> For example, pressing either button in the following code will cause both richBean.function1() and richBean.function2() actions.
> {noformat}
> <h:form id="testForm">
>     <a4j:commandButton id="button1" type="button" value="Button 1"
>         action="#{richBean.function1}" />            
>     <a4j:commandButton id="button2" type="button" value="Button 2"
>         action="#{richBean.function2}" />    
> </h:form>
> {noformat}
> Note, if one of the a4j:commandButton is marked immediate, then only one action (possibly the wrong action) will be performed and block others.  For instance if an a4j:jsFunction action was being triggered, the a4j:commandButton action may occur making appear that the a4j:jsFunction failed.
