I want to access a window component in project script. But it is giving me a following error. “AttributeError: ‘com.inductiveautomation.ignition.common.script.Imm’ object has no attribute ‘gui’”. I tried to use “import system” in project script, but still getting the same error. Does anyone have any idea, why system.gui is not getting imported. And how can i access window component in project scripts without opening window. Appreciated your help ---

That particular error occurs when the script is running in the gateway. The gateway has no GUI, so the system.gui.\* functions cannot possibly work, and are therefore omitted. Any script that needs to access a client’s windows and components needs to run as a client event script, not a gateway event script. ---

Can a component still be accessible event though a window is not running if try to access from client event script. ---

Yes but its not supported (and liable to break with Ignition updates), and is a pain to do. If you can rework things to use something else for that, that would probably be easier. ---

You are close. The value for that component is not `.value`. There are four different ones, like `.intValue` or `.floatValue`. Use the property name that corresponds to the mode you selected for the component. { Hover over the property's "pretty" name to get a tooltip with the scripting name. Or look in the manual. } ---

Look for a mistake in your names. Like extra spaces. ---

windows = system.gui.getOpenedWindowNames() #print windows # get list of all open windows if "Main Windows/MANUAL" in windows: # check if hookupunhookup is open main = system.gui.getWindow("Main Windows/MANUAL") button = main.getRootContainer().getComponent("Availability").getComponent("BREAK\_TIIME").intValue This code worked. Thanks@pturmel There was a extra I in BREAK\_TIIME component but that was not the issue, even with proper name I was getting error, but this above code did the job
