[jira] Created: (TOMAHAWK-734) DataScroller causes ClassCastException when actionListener is used.

DataScroller causes ClassCastException when actionListener is used.
-------------------------------------------------------------------

                 Key: TOMAHAWK-734
                 URL: http://issues.apache.org/jira/browse/TOMAHAWK-734
             Project: MyFaces Tomahawk
          Issue Type: Bug
    Affects Versions: 1.1.5-SNAPSHOT
         Environment: facelets 1.1.11
jsf ri 1.2.03 (recent nightly)
jboss 4.0.4 ga
            Reporter: reind


Here's my facelets code:

                    <t:dataScroller id="dataScroller" for="selectTable" styleClass="dataScroller" paginatorTableClass="paginator"                         
                         paginatorActiveColumnClass="paginatorActive"
                         pageIndexVar="pageIndex" pageCountVar="pageCount" 
                         paginator="true" paginatorMaxPages="9"	
                         actionListener="#{players$list.changeRowsPerPage}"
                         rendered="#{players$list.playersDataModel.rowCount > players$list.rowsPerPage}">
                        <f:facet name="first"><span>|&lt;</span></f:facet>
                        <f:facet name="last"><span>&gt;|</span></f:facet>
                        <f:facet name="previous"><span>&lt;</span></f:facet>
                        <f:facet name="next"><span>&gt;</span></f:facet>			
                    </t:dataScroller>	

then the action method:

    public void scroll(ActionEvent event) {
        log.info("scroll");
    } 

This causes the following exception to be thrown:

javax.servlet.ServletException: org.apache.myfaces.custom.datascroller.HtmlDataScroller

[jira] Resolved: (TOMAHAWK-734) DataScroller causes ClassCastException when actionListener is used.

Posted by "Leonardo Uribe (JIRA)" <de...@myfaces.apache.org>.
     [ https://issues.apache.org/jira/browse/TOMAHAWK-734?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Leonardo Uribe resolved TOMAHAWK-734.
-------------------------------------

    Resolution: Invalid
      Assignee: Leonardo Uribe

Checked tomahawk 1.1.7 and facelets 1.1.14 and the action listener works without problem. It seems to be a problem related to facelets so no further advance could be done here (no bug present in tomahawk!). So, this issue is closed as invalid, since it is not a tomahawk bug.

--------------------------------

To be clear: the exception is only thrown if an actionListener binding is used. If it is removed then it works as it should.

>                          pageIndexVar="pageIndex" pageCountVar="pageCount" 
>                          paginator="true" paginatorMaxPages="9"	
>                          actionListener="#{players$list.changeRowsPerPage}"
>                          rendered="#{players$list.playersDataModel.rowCount > players$list.rowsPerPage}">
>                         <f:facet name="first"><span>|&lt;</span></f:facet>
>                         <f:facet name="last"><span>&gt;|</span></f:facet>

>                     </t:dataScroller>	
> then the action method:
>     public void scroll(ActionEvent event) {
>         log.info("scroll");
>     }
