[Ruben Jorge (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-7456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12474045#action_12474045 ] 

Ruben Jorge commented on RF-7456:
---------------------------------

I'm very sorry, I found the problem and it was on my end.

One of the accessors for the variable had its name wrong. Once I fixed it, it worked fine.

Thank you very much anyway and sorry for wasting your time.

> rich:pickList works fine getting the option values from a variable, but if I associate it with a value (so that I can access the selected values), it crashes.
> The XML code I've tried is the following:
> [code]
> <rich:pickList value="#{SessionBean.tempSelectedValues}" copyAllControlLabel="Add all" copyControlLabel="Add">
>         <f:selectItems value="#{SessionBean.tempDistincts}"/>
> </rich:pickList>
> [/code]
> tempDistincts and tempSelectedValues are defined as:
> [code]
> private List<SelectItem> tempDistincts = new ArrayList<SelectItem>();
> private List<String> tempSelectedValues = new ArrayList<String>();
> [/code]
> If I remove the "value" attribute from the pickList, the option values are presented correctly, otherwise, the following error is generated:
> [code]
> java.lang.NullPointerException
