That warning was placed in there to prevent multiple DynLayers with
identical IDs from being added to the same DynDocument. All DynLayers
should have unique IDs, whether assigned manually or generated by the
widget code. This is especially important now that we are considering
going to only associative arrays in the all[] and children[]
collections.
I haven't looked at the code in a little while, but getComponent should
return a reference to the DynLayer itself, unless you overwrite it in
widget code.
So before the DynLayer is *created* by assigning it to a parent, the
return value would reference the unassigned array. After the DynLayer is
assigned, the return value should reference the all[] array of the
DynDocument that contains the DynLayer.
At least that's what *should* be happening. I'll download the latest
package and take a look.
