Step properties: the properties element

The properties element is a container for properties, which are defined with the property tag.

Each step has a single properties element; a properties element can contain any number of property child elements.

A property tag has a mandatory name attribute, optional required attribute, and two child elements, property-ui and value, which are defined in the following table.

Table 1. The <property> element
<property> Child Elements Description
<property-ui> Defines how the property is presented to users in the IBM® UrbanCode® Deploy editor. This element has several attributes:
  • label

    Identifies the property in the editor's Edit Properties dialog box.

  • description

    Text that is displayed to users in the associated roll-over help box.

  • default-value

    Property value that is displayed when the Edit Properties dialog box is displayed; used if unchanged.

  • type

    Identifies the type of widget that is displayed to users. Possible values are:
    • textBox

      Enables users to enter an arbitrary amount of text, limited to 4064 characters.

    • textAreaBox

      Enables users to enter an arbitrary amount of text (larger input area than textBox), limited to limited to 4064 characters.

    • secureBox

      Used for passwords. Similar to textBox except values are redacted.

    • checkBox

      Displays a check box. If checked, a value of true is used; otherwise the property is not set.

    • selectBox

      Requires a list of one or more values, which are displayed in a list. Configuring a value is described below.

<value> Used to specify values for a selectBox. Each value has a mandatory label attribute, which is displayed to users, and a value that is used by the property when selected. Values are displayed in the order they are defined.

Here is a sample <property> definition:

<property name="onerror" required="true">
  <property-ui type="selectBox"
    description="Action to perform when statement fails: continue, stop, abort."
    label="Error Handling"/>
  <value label="Abort">abort</value>
  <value label="Continue">continue</value>
  <value label="Stop">stop</value>
