Where is defined: isModuleOpen() and isPanelOpen() ?

[frankySie]

Both methods isModuleOpen() and isPanelOpen()
can't be found when
the method ModuleOnWithPanel() is called in a ctl-script. My ctl-script is located in ../scripts, the script-name is cn_service.ctl.

A use of #uses "panel.ctl" do not help because both methods are not defined here. And, as shown in the log-lines, the panel.ctl is available by default.
What should be the correct way to include both methods isModuleOpen() and isPanelOpen()

Hello,

the functions isPanelOpen() and isModuledOpen() can only be used in the UI-manager, therefore you get an error when calling them at a CTRL-manager.
