Re: [Dynapi-Help] child is nested in a parent

[Tarun R E. <ta...@we...>]

I too was suprised that getParentComponent() wasnt working ( I just bothered
to check now). However when I had a look at 'core.api.dynlayer.js', the
reason wasnt too suprising. The method getParentComponent() returns the
property 'this.parentComponent', however this property doesnt seem to be set
anywhere, and so remains undefined.

To get around the problem simply access the parent property of the DynLayer.
for example :
// Assuming myLayer has been defined and added as a child of myParentLayer
somewhere
myLayer.parent // gives parent object
// To check whether the child layer belongs to a specific parent, you can do
this
if (myLayer.parent == myParentLayer) { }
 // Alternatively you can define and set the "id" property of all the parent
layers like :
myParentLayer.id = "Pa";
if (myLayer.parent.id == "Pa")
// The second method might be preferable, when you have multiple references
to the same layer
// or  when you have both DynLayers and inline layers present, and you want
the code that accesses
// them to be the same.
