The following code example invokes the MyApplication/EncryptDocument.A
user must login to click the Select File button that is used to
upload a PDF file and invoke the process. That is, once the user
is authenticated, the Select File button is enabled. The following
illustration shows the Flex client application after a user is authenticated.
Notice that the Authenticated CheckBox is enabled.
if LiveCycle is configured to only allow secure documents
to be uploaded and the user not have the Document Upload Application User role,
then an exception is thrown. If the user does have this role, then
the file is uploaded and the process is invoked.
