addEventHandler - Bad argument problem.

[xuaNN]

Hello guys, im going to write a login panel for my server. 

Nearly, i finished. but i have this problem. 

How can i fix it?

function buttonClick()
    if source == rbRegister then
 		local username = DGS:dgsGetText(rUsername)
 		local password = DGS:dgsGetText(rPassword)
 		local email    = DGS:dgsGetText(rMail)
 		triggerServerEvent("registerRequest",getLocalPlayer(),getLocalPlayer(),username,password,email)
    elseif source == bLogin then
     	local username = DGS:dgsGetText(tUsername)
     	local password = DGS:dgsGetText(tUsername)
     	triggerServerEvent("loginRequest",getLocalPlayer(),getLocalPlayer(),username,password)

    end
end
addEventHandler("onDgsMouseClick",bar,buttonClick)

error = Bad argument @ 'addEventHandler' [expected element at argument 2,got nil]

Where did you define the `bar` variable? (created the button)

[xuaNN]

 local bar = DGS:dgsCreateImage(0.7 * fScreenX, 0 * fScreenY,  0.24 * fScreenX, 1 * fScreenY,_,false,_,tocolor(0,0,0,225))
   local logobs = DGS:dgsCreateImage(0.3, 0.05, 0.35, 0.25,"images/bslogo.png",true,bar)
   setCameraMatrix(-1999.56580, -1546.32251, 84.63199,-1997.58289, -1543.28892, 84.62630, 0, 70 )
   --login panel
   local tUsername = DGS:dgsCreateEdit(0.225, 0.3, 0.5, 0.03,"Username", true,bar)
   addEventHandler("onDgsMouseClick",tUsername, 
   	function ()
           DGS:dgsSetText(tUsername,"")
   		end
)
   local tPassword = DGS:dgsCreateEdit(0.225, 0.35, 0.5, 0.03,"Password",true,bar)
   addEventHandler("onDgsMouseClick",tPassword,
   	function ()
 		   DGS:dgsSetText(tPassword,"")
   	end
   	)

   local bLogin = DGS:dgsCreateButton(0.225,0.40,0.20,0.027,"Giriş Yap",true,bar)
   local bRegister = DGS:dgsCreateButton(0.525,0.40,0.20,0.027,"Kayıt Ol",true,bar)

there it is, bar is a image but it also serves as a window in the background.

The bar element:

local bar = DGS:dgsCreateImage(0.7 * fScreenX, 0 * fScreenY,  0.24 * fScreenX, 1 * fScreenY,_,false,_,tocolor(0,0,0,225))

 

Is not available here:

addEventHandler("onDgsMouseClick",bar,buttonClick)

 

Either:

- The addEventHandler is placed higher in the code, than where the bar is created.

- The addEventHandler is placed in another file, than where the bar is created.

- Or the bar has not been created at all.
