This Data
Nominated Subforms snippet demonstrates how one of several alternative
subforms can be displayed on the form based on a conditional statement. You
use data binding to set the condition that determines which of the
subforms appears on the form.
The subforms are wrapped in a subform set. In Designer, a subform
set can control the display of subforms based on the flow of data.
In this example, the Comedy subform is displayed each time the category
in the data equals comedy, the Action subform is displayed each
time the category equals action, and the Drama subform is displayed
each time the category in the data equals drama.
The alternative subforms are specified in the Edit Data Nominated
Subforms dialog box. To display this dialog box, select the Movie
subform set object and click Edit Alternatives on the Subform Set
tab of the Object palette.
To see similar examples, visit the LiveCycle Developer Center.
You must merge the form with data when generating the PDF file.
If not, the data will be unavailable for the script that decides
which subform to instantiate. Users who open the PDF file in Adobe®
Acrobat® will get a warning message. To avoid the warning, you can
add script to verify the existence of a data value before executing
the script.
