SUMMARY

This article explains how VAction containers work, so that developers can add more than one VAction to Voice Foundation Class (VFC) containers that accept VActions.

SYMPTOMS

Developer is building a VoiceXML document using the VFCs.  A VFC method accepts a VAction that will be added to the VoiceXML at runtime, but the developer needs to add multiple VActions.  An example is the VIfGroup class, which accepts a VAction for use in an if-else block.  It is often useful to execute multiple lines of VoiceXML (i.e. which are generated by VAction objects) within these blocks, rather than just a single line.

RESOLUTION

Although various VFC methods accept only a single VAction object reference, VAction objects are actually containers.  You can add any number of additional VAction objects to a given VAction object to form a list of VActions.  For example, if there is a VAction object named myVAction, one can add a second VAction named mySecondVAction to it by calling:

myVAction.add(mySecondVAction);

Now, myVAction can be passed to methods that accept a single VAction reference, and both VActions (myVAction and mySecondVAction) will be used to generate VoiceXML at runtime.
