Text Fields

Using Application Composer, you can extend an application's object model by adding new fields to both standard or custom objects. One such field type is a text field, where users in the runtime application can enter a combination of letters, numbers, or symbols.

Text Field Properties

Create a text field by specifying values for the common set of field properties, such as display label and field name. You also set properties for this field that are specific to the text field type.

The following properties are common across multiple field types:

Field Property	Field Property Region
Label	Appearance
Help Text	Appearance
Display Width	Appearance Note: Do not use. A field's display width is dynamically calculated based on the field type and resolution.
Name	Name
Description	Name
Required	Constraints
Updatable	Constraints
Searchable	Constraints
Indexed	Constraints
Fixed Value	Default Value
Expression	Default Value

The following properties are unique to only certain field types, including text fields:

Field Property	Field Property Region
Display Type The way you want this text field to render in the runtime application: As a simple text box. Allowing multiple lines where text can wrap or where the user can enter carriage returns.	Appearance
Maximum Length The maximum number of characters that a user can enter in the field. You can set a maximum length of 1500 characters. If the field is a multiline field, then carriage returns are permitted and count as part of the total. Note: The 1500-character limit applies if the characters are single byte. If the characters are multibyte, such as Japanese or Chinese, then the maximum character limit is 1500 characters divided by the number of bytes per multibyte character. For example, if characters are 2 bytes, then the name is limited to a maximum of 750 characters. If a mix of characters is used, then the maximum sum of character bytes that's supported is 1500.	Constraints
Minimum Length The minimum number of characters that a user can enter into the field.	Constraints

Maximum Length

The maximum number of characters that a user can enter in the field. You can set a maximum length of 1500 characters. If the field is a multiline field, then carriage returns are permitted and count as part of the total.

Note: The 1500-character limit applies if the characters are single byte. If the characters are multibyte, such as Japanese or Chinese, then the maximum character limit is 1500 characters divided by the number of bytes per multibyte character. For example, if characters are 2 bytes, then the name is limited to a maximum of 750 characters. If a mix of characters is used, then the maximum sum of character bytes that's supported is 1500.
