ADF: Insert Region Programatically

987779

Hello:

I'm using jdeveloper ver. 11.1.2.3.0 . I'm trying to add new RichPanelBox components, with a region inside to a page programatically. I create the RichPanelBox and place inside a RichRegion but when i use the .setValue method of the RichRegion to set the RegionModel I receive an error:

 <PropertyKey> <saveValue> Valor no serializable: oracle.adf.control[email protected]16f8890 para la clave: UINodePropertyKey[value,15]

I tried also with the .setValueExpression method and i'm receiving the same error.

Here is the chunk of code where i am having this problem:

        private void maximize(ActionEvent actionEvent) { 
        String id = actionEvent.getComponent().getId().replace("maximize_",""); 
        RichRegion region = new RichRegion(); 
        RegionModel regionModel = this.getRegionModelTaskFlow(id); 
        region.setId("region_"+id); 
        region.setValue(regionModel); 
         
        RichPanelBox panelBox=(RichPanelBox)JSFUtils.findComponentInRoot("maximized"); 
        panelBox.getChildren().add(region); 
         .
         .
         .
    }

What I'm trying to achieve is to add dynamically new PanelBoxes and assing to them a taskflow, all in runtime.

I saw a previous thread with likely the same problem is this (851878 in this case (2009) it was pointed that it was an ER.

Thanks
