Object name limitations

  • Last UpdatedMay 05, 2025

Object names must be unique within each namespace, not within the Galaxy.

  • Template names can be up to 32 alphanumeric characters, including the required $ as the first character. The second character cannot be $ and the name must include at least one letter. You cannot use spaces in an object name.

  • Instance names can be up to 128 alphanumeric characters. You cannot use $ as the first character. The name must include at least one letter. You cannot use spaces.

  • The object name extension "_New" cannot be used if another object in the Galaxy uses the same name without the "_New" extension. For example, if you have an object named "Pump," you cannot have a second object named "Pump_New." You could, however, use "Pump_Old" and "Pump_New."

    Note that this restriction applies to templates as well as instances. For example, you cannot have a derived template named "$Area_New" or "$ViewApp_New" since these add the "_New" extension to a base template name.

  • The following names are reserved and cannot be used for objects:

    • Me

    • MyArea

    • MyContainer

    • MyEngine

    • MyHost

    • MyPlatform

    • System
