I try to calculate the parentID for a custom control to access the custom properties via propertyMap()

 

Assume the following szenario:

 

- You have 2 custom controls ( cc-a and cc-b )

- cc-b has some custom properties

- you want to access this custom properties from cc-a ( cc-a is a custom control inside cc-b )

 

 I know, how to access the property and return the property value. I have the following function

 

function getPropertyValue(senderID, senderProp){
     if(null != senderID) {
        // get reference to the foreign custom control
        var senderComponent = getComponent(senderID);
        // get propertyMap of the foreign custom control
        var senderProperties = senderComponent.getPropertyMap();
        if(null != senderProperties) {
            // get senderProp value from the PropertyMap
            var ret = senderProperties.getProperty(senderProp);
            if (null != ret){
                return ret;
            }else {
                // if there is no such property return null
                return null;
            }
        }
    }
}

 

I can set the senderID to a static value and the code works, but I want to calculate the senderID of cc-b at runtime.
