Is there a limit on the number of graphics that the GraphicUtil.getGraphicsExtent can use? I'm doing some work on an application and it gets a list of locations passed in from an external system. I take these, and generate an array of graphic elements and then pass that to the function to get the full extent of the graphics. However, if there are more than a couple of thousand points in the array the function fails with an error. "TypeError: Error #1009: Cannot access a property or method of a null object reference." If there are fewer graphics in the array it works just fine. Didn't see any documented limit but obviously something isn't working with larger number of graphics in the array?
