Having the following code snipet:

Print "Entering"
imgPart=New TPixmap[4]
For Local i:TPixmap=EachIn imgPart
imgPart[index] = PixmapWindow(origImage,(x*partWidth-partWidth ) ,(y*partHeight-partHeight ),partWidth,partHeight)
'Print index+" - "+x+" - "+y+ " - "+(x*partWidth-partWidth )+" - "+(y*partHeight-partHeight )+" -- "+(index Mod 2)
If (x Mod (Int(Sqr(pieces)))) =0
y=y+1
x=1
Else
x=x+1
EndIf
Print index
index=index+1
Next
Print "Leaving"

the for loop is never entered. something that was working in MAX 1.12 Is there any difference in the new 1.14 with null objects?

Thank you

You can't use an Eachin on an array of nulls.
Although you define your array as containing 4 pixmaps, you've only created the array, not the data to fill it, and Eachin won't work.
Instead use

For Local index:int = 0 to 3

Once your array is populated, you could use the EachIn.
