IDs

Identifiers or IDs in the lsFusion language are used for naming or referring to system elements, parameters of properties and actions, static objects, properties and actions on a form, and other entities.

Simple ID​

Simple ID is a basic building block for creating other identifiers. It consists of a sequence of uppercase and/or lowercase Latin letters a-zA-Z, digits 0-9, and the underscore character _. The first character of a simple ID must be a letter. Names beginning with an underscore are reserved for internal system names.

Simple IDs are used mainly as names for system elements and as names for parameters of properties and actions.

Examples​

name
value_id13
bankAccount

Composite ID​

[namespace.]name

Composite ID is used to reference a system element by name, with the option of specifying а namespace. It can consist of either a single simple ID or two simple IDs separated by a dot. If you need to specify a namespace, you first specify the namespace name, then a dot, followed by the name of the system element.

Examples​

System.name
Sale.Document
name

Class ID​

Class ID is used to reference either a user or built-in class. For a user class, the identifier is represented as a composite ID, while for a built-in class, special keywords are used to specify the built-in class.

Examples​

System.Object
Barcode
INTEGER
STRING

Static object ID​

[namespace.]className.objectName

Static object ID is used to reference a static object of a class. It consists of a user class ID and a simple ID (name of the static object) separated by a dot.

Examples​

Direction.north
System.FormResult.ok

Property or action ID​

Property ID or action ID is used to reference a property (action). In the simple case it is a composite ID that specifies the name of the property (action) and possibly its namespace, similar to any other named system element. In the general case, this composite ID is supplemented by a description of the property (action) signature, which describes the classes of the property (action) parameters. The signature is specified as a list of class IDs enclosed in square brackets. If the parameter class is unknown or not important for uniquely identifying the property (action), its ID in the list can be replaced with a question mark ?.

Examples​

userRole
Security.userRole
userRole[System.User]
cross[Circle, Line]
quantity[Document, ?, Store]

Property or action on a form ID​

[namespace.]formName.formPropertyName

Property on a form ID or action on a form ID is used to reference a property or action added to a form. It consists of a composite ID that specifies the form and the name of the property (action) on a form, separated by a dot.

Examples​

barcodeSku.amount(b)
Item.items.name(i)
Consignment.dashboard.date

Group object ID​

Object group ID is used to reference an object group (or object) on a form. It consists of a composite ID that specifies the form and the name of the object group (or the name of the object), separated by a dot.

Examples​

storeArticle.s
Item.form.object

Typed parameter​

[classID] name

Typed parameter is used to reference a property (or action) parameter (action). It consists of an optional parameter class ID and a simple ID representing the parameter's name.

Examples​

user
User user
System.User user
INTEGER count
