[Xerte] Re: Array length when none expected

[Julian Tenney]

The xml is a red herring:

This explains it:

string = "hi";
arr = string.split('~');
debug(arr.length); //debugs 1?
debug(arr[0]); //debugs hi

So:

string = ""; //AN EMPTY STRING
arr = string.split('~');
debug(arr.length); //debugs 1
debug(arr[0]); //debugs EMPTY STRING

Subject: [Xerte] Array length when none expected

feedback_right is an XML CDATA node that is read in

<RRIGHT x="50" y="200">
      <![CDATA[]]>
    </RRIGHT>

rarray = feedback_right.toString().split('~');
debug(feedback_right); //blank
debug(rarray); //blank
debug(rarray.length); // 1

Why is it exhibiting length?
