>             Project: MyFaces Core
>          Issue Type: Bug
>    Affects Versions: 2.3.0-beta
>            Reporter: Jay Sartoris
>            Assignee: Thomas Andraschko
>            Priority: Minor
>             Fix For: 2.3.0

> The vdldoc for the h:commandScript component state that "@this" should be the default value for the "execute" attribute. 
> The excerpt from the execute attribute description in vdldocs/facelets/h/commandScript.html is:
> -------
> This is a space separated list of client identifiers of components that will participate in the "execute" portion of the Request Processing Lifecycle. If a literal is specified the identifiers must be space delimited. Any of the keywords "@this", "@form", "@all", "@none" may be specified in the identifier list. *If not specified, the default value of "@this" is assumed.* For example, @this clientIdOne clientIdTwo.
> -------
> When I specify the component like this (without an execute attribute):
> {code:java}
> <h:form id="form1">
>     <h:commandScript name="commandScript1" action="#{commandScriptBean.testCommandScript('success')}" render=":output1" autorun="true"/>
> </h:form>
> <h:outputText id="output1" value="MyFaces test output: #{commandScriptBean.output}" />
> {code}
> I receive the following exception:
> {noformat}
>  java.lang.NullPointerException

> When I try the same example using the Mojarra RI, it works as expected.  
> I tried this with the MyFaces 2.3.0-beta and also several snapshots however, the issue still occurs.  The latest snapshot I tried was the 20171010.124738-264 version of the impl.  
> I will upload a sample application to help reproduce the issue.
