! 	<p><strong>Subscriptions</strong> component performs the following functions:</p>
! 	<ul>
! 	<li>Displays a list of email subscriptions</li>
! 	<li>Allows to create a new sibscription</li>
! 	<li>Allows to update existing subscription</li>
! 	</ul>
! 	<p>Subscriptions component is controlled by one action (SubscriptionAction.java) 
! 	and has two views: <code>subscriptions.jsp</code> and <code>subscription.jsp</code>.</p>
! 
! 	<p><code>subscriptions.jsp</code> displays a list of email subscriptions.
! 	It is shown to a logged-in user, if there is no <em>current</em> subscription.</p>
!  	<figure src="images/mailreader-subscriptions.gif" alt="MailReader Subscriptions"/>
! 	<p/>
! 	<p>If current subscription exists, <code>subscription.jsp</code> displays it 
! 	to a logged-in user. It can be either a new subscription...</p>
!  	<figure src="images/mailreader-subscription-create.gif" alt="MailReader Create Subscription"/>
! 	<p>...or an existing subscription:</p>

! 	<p><code>SubscriptionAction</code> class does not differ much from standard
! 	all-in-one <link href="crudaction.html">CRUD Component</link>. The major difference
! 	is that Subscription action first verifies if a user is logged in. If not,
! 	it redirects to Login action. If user is logged in, then Subscription action
! 	handles input events in standard way for DialogAction class. In real application
! 	this code should be placed in an interceptor or servlet filter. Struts Chains,
! 	introduced in Struts 1.3, should allow easy implementation of generic interceptors
! 	like login interceptor.</p>

! 	<p>The major difference of this version of MailReader application from original
! 	Ted Husted's version is that action form has session scope and current subscription
! 	is nested within the action form. Fortunately, Subscrption business object (BO)
! 	has only String and boolean fields, so no conversion is needed and it is easy to
! 	retain invalid values in the form.</p>
! 	<p>When a user creates new subscription, a new <code>Subscription</code> object is created and
! 	nested in the <code>SubscriptionForm.java</code> class. If a user wants to update
! 	existing subscription, then it is cloned into a detached object, which in turn, is
! 	nested within <code>SubscriptionForm.java</code> class. Therefore, changes to 
! 	nested subscription do not affect persistent data. If the user cancels the update
! 	process, then detached subscription is simply deleted from memory.</p>
! 	<p>Subscription action creates new or updates existing subscription based on input
! 	event generated by button on <code>subscriptions.jsp</code> page. DIALOG-EVENT-CREATE
! 	creates new subscription, DIALOG-EVENT-UPDATE selects a subscription as current and
! 	updates it.</p>
