Variables support multiple data types including boolean, date, decimal, and so on. Variables without a domain definition may remain unbound, leading to errors.
| Data Type | Description | Defaulting Example |
|---|---|---|
| boolean | Only true, false, or null can be assigned as a value. | @(defaultValue="true") boolean isActive; |
| date | A value that indicates a particular day, the same as local date in Java. | date shipDate = ["2023-01-01".."2023-12-31"]; If there’s no defaultValue specified, the variable defaults to the first value in the domain. See the Constraints using Format Specifiers (%s, %d) and Dates example. |
| double(n) | A 64-bit number that includes a decimal point, the same as double in Java. | double(2) percentage = [0.00..100.00]; If there’s no defaultValue specified, the variable defaults to the first value in the domain. |
| decimal(n) | A fixed-point numeric value with n decimal places. Note: The decimal variable data type isn’t supported for the quantity field in quote line items. Use the integer data type for the quantity field. | decimal(2) TaxRate = 0.08; |
| int | Integer. A 32-bit number that doesn’t include a decimal point, the same as int in Java. | @(defaultValue = "5") int defaultQty = [1..10]; If there’s no defaultValue specified, the variable defaults to the first value in the domain. |
| string | Any set of characters surrounded by double quotes (“) | @(defaultValue = "Red") string color = ["Red", "Green", "Blue"]; If there’s no defaultValue specified, the attribute defaults to the first value in the domain. |
| string[] | Used in multi-select picklists for the user to select more than one item from multiple options. For example, if a user selects “Red”, “Green”, and “Blue” values in a color picker, this variable holds those selected values. | @(defaultValue = '["Red", "Green"]') string[] selectedColors; If there’s no defaultValue specified, the attribute picklist defaults to the first value in the domain. |
In string variable values, commas may be interpreted as delimiters in certain CML contexts. Avoid commas in variable values or use alternative approaches, such as encoded strings or separate fields.
