> In SLING-282, Michael Marth writes:
> the property "to" is multivalued.
> in the script I do something like:
>  <%= currentNode["to"][0] %>
> if the value of "to" has only one value I seem to get back this value as one string so [0] gives me the first character. if "to" has 2 values I get back a collection so [0] gives me the first element. this is consistent with what ["to"].length gives me.
> I am not 100% sure if this is a bug (might be my lack of understanding for javascript), if so a comment on how to determine the result length of a multi-valued property would be appreciated.
