What is the deal with this array print?? Weird.

Usually when I have a problem, it’s something easy that I’m overlooking or some little detail I wasn’t aware of. I’m sure this is the case here. I have an XML;


<feed>
<setmusic y="75" h="120">
    <option>
        <sd font="0" size="1" X="50" Y="100" W="180" H="100" />
        <hd font="0" size="1" X="50" Y="100" W="340" H="180" />    
        <color>000066FF</color>
        <selected>0000FFFF</selected>
        <text>All Music Random</text>
        <textcolor>FFFFFFFF</textcolor>
    </option>
    <option>
        <sd font="0" size="1" X="260" Y="100" W="180" H="100" />
        <hd font="0" size="1" X="50" Y="100" W="340" H="180" />
        <color>000066FF</color>
        <selected>0000FFFF</selected>
        <text>List 1 Random</text>
        <textcolor>FFFFFFFF</textcolor>
    </option>
    <option>
        <sd font="0" size="1" X="480" Y="100" W="180" H="100" />
        <hd font="0" size="1" X="50" Y="100" W="340" H="180" />
        <color>000066FF</color>
        <selected>0000FFFF</selected>
        <text>List 2 Random</text>
        <textcolor>FFFFFFFF</textcolor>
    </option>
</setmusic>
</feed>

and my script is:


	for idx = 0 to (homexml.setmusic.option.count() -1 )
		item.text = homexml.setmusic.option[idx].text.gettext()
		item.textcolor = homexml.setmusic.option[idx].textcolor.gettext()
		print ""
		print idx.tostr() "-------"
		items.push(item)
		print homexml.setmusic.option[idx].text.gettext()
		print items[idx].text
		print "--------"
		
	next
	
	for idx = 0 to (homexml.setmusic.option.count() -1 )
		print ""
		print idx.tostr() "++++++++"
		print homexml.setmusic.option[idx].text.gettext()
		print items[idx].text
		print "+++++++++"
	next
	
	print "-------"
	print items[0].text
	print items[1].text
	print items[2].text
	print "-------"

which puts out:


0-------
All Music Random
All Music Random
--------

1-------
List 1 Random
List 1 Random
--------

2-------
List 2 Random
List 2 Random
--------

0++++++++
All Music Random
List 2 Random
+++++++++

1++++++++
List 1 Random
List 2 Random
+++++++++

2++++++++
List 2 Random
List 2 Random
+++++++++

-------
List 2 Random
List 2 Random
List 2 Random
-------

so the issue is, when I do print items[idx].text the first time it prints correctly. when I do it again, it does not. Also incorrect when I pick an array index manually. How does it get to the point that it prints the same text for all three instead of the different three texts?

Oooh, this one was a doozy!
In the first loop you kept modifying the very same item, so at the end all items[] ends up pointing to exactly the same element. You have to create new item on every iteration. Say by inserting item = { } on the next line after for idx....

A more elegant way to do the same is

   for each option in homeXml.setmusic.option
      item = { 
          text: option.text.getText(), 
          textcolor = option.textcolor.getText() 
      }
      items.push(item)
      'print option.text.getText()
      'print item.text
      'print "--------"
   next
