controlp5 scroll list error
Dec 19th, 2008, 9:56pm  
I am currently creating a GUI to control a series of animations. I have an empty scroll list to which a new item is added every time an animation runs (basically contains a list of all active animations at any given time). When an animation stops running, a listener is activated and it should be removed from the list. The problem I am running into is an error when I remove an item when only one exists in the scroll list:

Code:

Exception in thread "Thread-9" java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 1
at java.util.Vector.get(Unknown Source)
at controlP5.ControllerList.get(Unknown Source)
at controlP5.ScrollList.removeItem(Unknown Source)
at net.electroland.lafm.gui.GUI.removeActiveShow(GUI.java:70)
at net.electroland.lafm.core.Conductor.notifyComplete(Conductor.java:202)
at net.electroland.lafm.core.ShowThread.run(ShowThread.java:129)


Any ideas?

A quick follow up:
I added a placeholder item as the first thing, then dynamically added and removed an item and got another arrayindexoutofbounds exception with a value of 2 this time.

Could this potentially be a threading conflict?
