The id field

Associates an identifier with a control so that the control's properties can be referenced in data-binding queries, reports, and workflow scripts.

Usage

<parent-control
  id="identifier"
/>

Parameters

Parameter Description
identifier (required) The identifier of the parent control.

Remarks

Must begin with a letter or an underscore.

The id field is optional, but a control without an identifier cannot be referenced elsewhere in the solution, and its values are not submitted to the server when the user submits the containing form.

An id must be unique within its scope. Each control that has an id field declared defines a new scope: the descendants of a control with an id are within its nested scope. See the section on scoping for further details.

Sample

scopesSample.fls.xml

...
<popup title="Reference to a named control from a sibling">
  <textbox id="boxFoo"
    label="Type something"/>
  <textview label="Your text input:"
    text='{boxFoo.text}'/>
</popup>
...

The textview control references the input in the textbox control above it

A workflow script running in the Mobilengine Cloud would access the submission of the webform above in the format below:

{...
  boxBar: {text: "My hovercraft is full of eels"},
...}

See the workflow script reference guide for more details on data type mapping.
