There is is beforeRenderResponse event associated with custom control. I would like to place the script there and read custom control property. It seems that compositeData object is not instantiated at that time. To overcome that I am using PropertyMap as shown in the code below. Although the solution works fine there is hard coded custom control ID (ID is assigned on XPage where cc is embedded to, mycustomcontrolID in the code snippet below) which makes its portability quite limited.

My question is if there is a way how to compute the current component ID from within the event?

 

 

 

var thisCCComponent = getComponent( "mycustomcontrolID" );

if ( thisCCComponent != null ){

    var componentProps = thisCCComponent.getPropertyMap();

    if  ( componentProps != null ) {
       
        var auxComponent = getComponent( componentProps.getProperty( "firstNameID" ) );
        viewScope.firstName = auxComponent.getValue() ;
       
    }
}
