[JW Lua] FCPageTexts - Retrieve Item at a specific index

[Jari Williamsson]

Hello again Bruce,

I now see that you got a bad answer to your question.
Better answer is, use this pseudo code (rather than verifying cmper/inci 
stuff):

1. Load all available text blocks with LoadAll()
2. Iterate through all the text blocks with each()
3. If you find a text block you want to change in the iteration loop, 
change the properties and save the object with myobject:Save()
4. If you don't find the object you need in the collection/loop, create 
a new one. This new object will not be a part of the objects you 
previously loaded with LoadAll().



Best regards,

Jari Williamsson
