Forward referencing an ui button

Solar2D General Questions/Discussion

Is there a way to forward reference an ui button as we can do with other components. Check the attached code:

 local act\_action\_421   
   
 local Shape1   
 local Layer1   
  
 function act\_action\_421 (event)   
 transitionStash.newTransition = transition.to( Shape 1, {alpha=0, time=1000, delay=0})   
 end   
  
 Layer1 = display.newImageRect( imgDir.. "p1\_layer1.png", 1024, 768 );   
 Layer1.x = 512; Layer1.y = 384; Layer1.alpha = 1   
 local onShape1Touch = function(event)   
 if event.phase=="ended" then   
 act\_action\_421()   
 end   
 end   
 Shape1 = ui.newButton{   
 defaultSrc=imgDir.."p1\_shape1.png",   
 defaultX = 280,   
 defaultY = 70,   
 overSrc=imgDir.."p1\_shape1.png",   
 overX = 280,   
 overY = 70,   
 onRelease=onShape1Touch,   
 id="Shape1Button"   
 }   
  
 Shape1.x = 401; Shape1.y = 362; Shape1.alpha = 1

When the button is hit, I get the following error (originally the transitionStash line is 23):

error loading module ‘page_1’ from file ‘/Users/mac/Documents/Kwik/toLixo/build/page_1.lua’:
/Users/mac/Documents/Kwik/toLixo/build/page_1.lua:23: ‘)’ expected near ‘1’
Ideas??

Hello, on line 7 you have an extra space on the first argument passed to transition.to()

Should be like this:

[lua]transitionStash.newTransition = transition.to( Shape1, {alpha=0, time=1000, delay=0})[/lua]
