Loadable Detachable Model not updating on re-render

Hi,

This question is related to LoadableDetachable Model.

I have a wicket panel, LearningCurveChartPanel.

   *public* LearningCurveChartPanel(String aId, IModel<AnnotatorState>
aModel)

    {

        *super*(aId);

        model = aModel;


        //initially the chart is empty. passing empty model

        chartPanel = *new* ChartPanel(*MID_CHART_CONTAINER*,

                LoadableDetachableModel.*of*(*this*::renderChart));



        chartPanel.setOutputMarkupId(*true*);

        add(chartPanel);

    }

    @OnEvent

    *public* *void* onRenderAnnotations(RenderAnnotationsEvent aEvent)

    {

        LOG.trace("rendered annotation event");


        aEvent.getRequestHandler().add(*this*);

    }


which is rendering a ChartPanel. The ChartPanel is like this

 *public* ChartPanel(String aId, LoadableDetachableModel<LearningCurve>
loadableDetachableModel)

    {

        *super*(aId);



        chartModel = (loadableDetachableModel);


        chart = *new* WebMarkupContainer(*MID_CHART_CONTAINER*);

        chart.setMarkupId("canvas");

        chart.setOutputMarkupId(*true*);

        add(chart);


        chartAjaxBejavior = *new* ChartAjaxBejavior();

        add(chartAjaxBejavior);

    }


The chartModel has the right data and it renders correctly with the data
that is fed to it from LearningCurveChartPanel.

But when the onRenderAnnotation event of the LearningCurveChartPanel
triggers what I am trying to do is to update the (re-render) the Chart
Panel inside it. It does re-render the chart panel but the model stays the
same. I want to implement it such that the model of the ChartPanel updates
and when it re-renders it as the latest data when the onRenderAnnotation
event was triggered.

Please guide me in the right direction.

Best,
Sibgha

There is one more thing regarding the same code. Here I am adding
ChartPanel in the constructor of LearningCurveChartPanel and as the
LearningCurveChartPanel loads the chart panel is loaded with the data that
is returned by renderChart. I want to do such that the ChartPanel only
renders when I click a button. How do I change the below line to

chartPanel = *new* ChartPanel(*MID_CHART_CONTAINER*,

                LoadableDetachableModel.*of*(*this*::renderChart));

And how do I define such thing in the onClick event?

Best,
Sibgha

Re: Loadable Detachable Model not updating on re-render

Hi,

I tried doing the following

*public* ChartPanel(String aId, LoadableDetachableModel<LearningCurve>
loadableDetachableModel)

    {

        *super*(aId*,**loadableDetachableModel*);



        chartModel = (loadableDetachableModel);


        chart = *new* WebMarkupContainer(*MID_CHART_CONTAINER*);

        chart.setMarkupId("canvas");

        chart.setOutputMarkupId(*true*);

        add(chart);


        chartAjaxBejavior = *new* ChartAjaxBejavior();

        add(chartAjaxBejavior);

    }

It still doesn't update the ChartPanel with the new model when
onRenderAnnotations triggers. Do I have to explicitly call detach()?

Hi,
 

 
that should do it, no need to call detach() for yourself.
 

 
Hard to tell what's going wrong.    Can you create a quickstart?

Hi,
 

 
your chartPanel should pass the chartModel to the super constructor. The panel takes care that the model is detached after the request.
 

 
If you just hold chartModel as a member variable, no one will call detach() on it
 

 
Have fun
 
Sven

>  Hi, This question is related to LoadableDetachable Model. I have a wicket panel, LearningCurveChartPanel. *public* LearningCurveChartPanel(String aId, IModel aModel) { *super*(aId); model = aModel; //initially the chart is empty. passing empty model chartPanel = *new* ChartPanel(*MID_CHART_CONTAINER*, LoadableDetachableModel.*of*(*this*::renderChart)); chartPanel.setOutputMarkupId(*true*); add(chartPanel); } @OnEvent *public* *void* onRenderAnnotations(RenderAnnotationsEvent aEvent) { LOG.trace("rendered annotation event"); aEvent.getRequestHandler().add(*this*); } which is rendering a ChartPanel. The ChartPanel is like this *public* ChartPanel(String aId, LoadableDetachableModel loadableDetachableModel) { *super*(aId); chartModel = (loadableDetachableModel); chart = *new* WebMarkupContainer(*MID_CHART_CONTAINER*);   chart.setMarkupId("canvas"); chart.setOutputMarkupId(*true*); add(chart); chartAjaxBejavior = *new* ChartAjaxBejavior(); add(chartAjaxBejavior); } The chartModel has 
the right data and it renders correctly with the data that is fed to it from LearningCurveChartPanel. But when the onRenderAnnotation event of the LearningCurveChartPanel triggers what I am trying to do is to update the (re-render) the Chart Panel inside it. It does re-render the chart panel but the model stays the same. I want to implement it such that the model of the ChartPanel updates and when it re-renders it as the latest data when the onRenderAnnotation event was triggered. Please guide me in the right direction. Best, Sibgha
