[Xerte-dev] Re: icons killed on page turn?

[Julian Tenney]

I had thought about handling this in the engine and having something in XMLNode.prototype.duplicate() that would say

If (this.built != true){
  //dupe away...
  this.built = true;
}

But wasn't sure if you'd ever want to run it more than once. I suppose that could be overridden, like

icon.nextSibling.duplicate(n, true);// insists on the dupe even if it's been done before.

More or less, yes. If you initialise anything in there, it won't be initialised again when the page is re-made.

What it stops happening is this:

SCR //icon.nextSibling.duplicate(numOfIcons - 1)
DIS //an icon...

...shows numOfIcons icons, right?

If you let that dupe code run again when the page is re-encountered, you're gonna end up with twice as many icons etc.

So that logic should really only wrap dupe statements?

icon is the xml. So it only needs the duping done once: if the resulting movieclip is killed, the xml still exists in its manipulated state ready to be parsed again.

J, when do icons get killed?

I have this logic in calcs all over the place:

if (icon.built != 'true') {

blah


and thought that it would reset to undefined upon page turn, but I'm finding that not the case.
