Re: [Trinidad] Trinidad 2.0.0 chart tag with Facelets and component binding

[Max Starets]

Andrew,

Rather than patching TrinidadComponentHandler, the better idea is to 
either modify CoreChart (to implement getChartDrillDownListeners()) or 
create a separate handler for the chart, where createMetaRuleset() would 
be overridden. Once you file a jira issue, we will try to provide a fix 
as soon as possible.

Hi Max,

Thanks for your quick reply!
I found this "protected MetaRuleset createMetaRuleset(Class type)" 
method in the trinidad-impl.jar TrinidadComponentHandler class.
This class should be patched?

What is your standard way for doing this?
I file this issue in JIRA and wait.
When and in which release this supposed to appear?

Thanks,

    Hey Andrew,

    The problem is that the Facelets engine does not know it is
    dealing with a MethodExpression.

    One way to fix it would be to override  createMetaRuleset() in the
    newly created chart tag along these lines:

    protected MetaRuleset createMetaRuleset(Class type)
    {
        MetaRuleset m = super.createMetaRuleset(type);
        m.addRule(new MethodRule("chartDrillDownListener", null, new
    Class[]|{ChartDrillDownEvent|.class}));
        return m;
    }

    Another way would be to implement getChartDrillDownListeners() on
    CoreChart, so that TrinidadListenersTagRule can add a rule
    automatically.

    Both ways involve making changes to Trinidad code. Could you file
    a JIRA issue for this?

    Thanks,
    Max

    Hi,

    I'm trying to user Trinidad charts and I have problems with th
    chartDrillDown listener and also with the binding of the chart component to
    an UIComponent.

    1.)
    If I use a JSPX page with jsp:root and f:view tags, so withOUT Facelets it
    all works fine...the chartDrillDown fires up.

    2.)
    If inside ui:composition tags, so WITH facelets the problem is, that the API
    tries to look up the chartDrillDownListener as a property not as a
    MethodExpression.

    This is also the case with bindig the tr:chart element to an UIComponent.

    I debugged the class UIXChart, as the event travels throught its
    "broadcast(FacesEvent event)" method.

    // Deliver to the default ChartDrillDownEvent
    if (event instanceof ChartDrillDownEvent) {
    broadcastToMethodExpression(event, getChartDrillDownListener());
    }
    super.broadcast(event);


    In case of FACELETS the getChartDrillDownListener() method tries to call
    getProperty() for UIXComponentBase and exits with a
    PropertyNotFoundException.
    Any suggestions?
    Thanks in advance...
