This affects both the public release and current daily builds.
There seems to be an issue (probably an update to the Git repository is needed).
If you use the repository included with the build things work as expected however if you use the code in the repository you get the following error.
Attempt to perform arithmetic on field ‘_oldAnchorX’ (a nil value)
easy to test with the following code (from the included doco) - you can swap between
local widget = require ("widget ") and require(“widgetLibrary.widget”)
local widget = require( "widget" ) -- Function to handle button events local function handleButtonEvent( event ) if ( "ended" == event.phase ) then print( "Button was pressed and released" ) end end -- Create the widget local button1 = widget.newButton { left = 100, top = 200, id = "button1", label = "Default", onEvent = handleButtonEvent }
