hostPseudoModel

The hostPseudoModel object is the root object of the host model. Use the host properties and methods at run time.

Examples of hosts include Acrobat and XFAPresentationAgent (server). Some hosts may not support all properties and methods. For example, XFAPresentationAgent does not support xfa.host. messageBox .

The properties or methods return different values depending on the rendering agent. When executed on a server the scripts return values of the server environment and when executed on a client, like Adobe Acrobat or web browser, the scripts return values of the client. For example, xfa.host.version returns XMLFM version when executed on a server and returns the Adobe Acrobat version when executed in Adobe Acrobat.

For desired results, develop according to these API differences.
