When you build a Pega composite
application with Internet Application Composer, you embed the
application on an external Web page as a gadget in a <DIV >
element. A Data Field is an invisible field that makes the value of a
scalar, single-value property from the composite application available to
the external page. For example, say you want to display the
operator's organization in a heading at the top of the external Web
page. In such a case you add a Data Field for
.pyOrganization to the harness or one of the sections or
flow actions.
The external page hosting a composite application can access only
those properties that are represented by a Data Field control somewhere
in the harness displayed by the <DIV >. The values of these
properties are read-only.
1. Drag and
drop the Data Field control
Click the down-arrow () at the right end of the
Advanced control group () and
select the Data Field control (). Drag the control to the cell or
header that is to contain the property value. When the pointer changes
shape to indicate that a single cell is selected, release the mouse
button to drop the control.
If you drop the control into a cell that already has contents, it
replaces the current contents of the cell.
2. Complete the
Cell properties panel — Top fields
Click the magnifying glass () icon to display the Cell Properties
panel.
Your updates to this panel can update the rule form immediately or
upon clicking Apply, depending on the
Property Panel settings in your Edit
preferences. See Setting your preferences.
If the panel is pinned(), the wireframe on the rule
form changes immediately to reflect your inputs. If the panel is not
pinned(), click Apply to apply your inputs.GRP-229
