[LDTP-Dev] About waittillguiexist() function

[Nagappan]

Hi Mauricio,
    waittillguiexist function will wait till maximum of 30 seconds or 
till the window appears. In either case, the function will return. The 
sleep duration is in nano seconds. In your example, the control from 
waittillguiexist function returns immediately after the window appears. 
But by that time, the control inside the window are not ready. I mean 
the object property inside the new window are not ready. Thats the 
reason why you are getting this failure. The wait command can be used to 
overcome this situation. This can't be handled in waittillguiexist 
function, because the wait delay depends on the system load. On a slow 
system, this wait time should be increased more...

Thanks
Nagappan
