Text Inputs
Single line text inputs are <input type="text"> controls. Single line text inputs are the most
common input field and allow the user to provide values for different data types.
Binding Text Input to a Process Variable
A text input can be bound to a process variable using the cam-variable-type and
cam-variable-name directives:
<input type="text"
cam-variable-name="CUSTOMER_ID"
cam-variable-type="String" />
In the example above, the text input field is bound to the variable named CUSTOMER_ID of type
String.
Supported Variable Types for Text Inputs
A text input field supports multiple variable types.
Binding to existing variables: Note that if you bind the input field to an existing variable,
the type of the variable is provided by the process engine and the cam-variable-type directive
is not required.
String
To bind the input field to a String variable, the directive cam-variable-type="String"
must be used.
Example:
<input type="text"
cam-variable-name="CUSTOMER_ID"
cam-variable-type="String" />
Trimming: Note that the value of the String variable is trimmed before it is submitted to the process engine: leading and trailing whitespace is removed.
Integer
To bind the input field to a Java Integer variable, the directive
cam-variable-type="Integer" must be used.
Example:
<input type="text"
cam-variable-name="CUSTOMER_AGE"
cam-variable-type="Integer" />
Long
To bind the input field to a Java Long variable, the directive
cam-variable-type="Long" must be used.
Example:
<input type="text"
cam-variable-name="CUSTOMER_REVENUE"
cam-variable-type="Long" />
Short
To bind the input field to a Java Short variable, the directive
cam-variable-type="Short" must be used.
Example:
<input type="text"
cam-variable-name="CUSTOMER_REVENUE"
cam-variable-type="Short" />
Double
To bind the input field to a Java Double variable, the directive
cam-variable-type="Double" must be used.
Example:
<input type="text"
cam-variable-name="CUSTOMER_REVENUE"
cam-variable-type="Double" />
