back and cancel button on a pages containing input field
My pageflow diagram is shown below. All the "next" buttons on the pages work well but I have a question for the back and cancel button (on the page, but not brower's back button). When there is a page containing input fields, after the clicking the back or cancel button, the validation of the input fields still happened. I had to input some dummy values in order to go back or cancel. This is not natural and how can I go back and cancel immediately without validation? The pageflow is managed by a jpdl file:
<pageflow-definition name="roomBookingFlow">
<start-state name="start">
<transition to="preference" />
</start-state>
<page name="preference" view-id="/reservations/preferences.xhtml">
<redirect />
<transition name="pricing" to="checkAvailability">
<action expression="#{roomBooking.doPricing}" />
</transition>
<transition name="cancel" to="cancelPage" />
</page>
<decision name="checkAvailability"
expression="#{roomBooking.roomAvailable}">
<transition name="true" to="checkLoggedIn" />
<transition name="false" to="preference"/>
</decision>
<decision name="checkLoggedIn" expression="#{login.loggedIn}">
<transition name="true" to="payment" />
<transition name="false" to="loginPage" />
</decision>
<page name="loginPage" view-id="/login.xhtml">
<transition name="login" to="payment">
<action expression="#{login.login}" />
</transition>
<transition name="newguest" to="payment">
<action expression="#{register.startEdit}" />
</transition>
<transition name="back" to="preference" />
<transition name="cancel" to="cancelPage" />
</page>
<page name="payment" view-id="/reservations/payment.xhtml"
no-conversation-view-id="/reservations/preferences.xhtml">
<redirect />
<transition name="next" to="checkPayment" />
<transition name="back" to="preference" />
<transition name="cancel" to="cancelPage" />
</page>
<decision name="checkPayment"
expression="#{roomBooking.validPayment}">
<transition name="true" to="review" />
<transition name="false" to="payment" />
</decision>
<page name="review" view-id="/reservations/review-details.xhtml"
no-conversation-view-id="/reservations/preferences.xhtml">
<redirect />
<transition name="book" to="confirmation">
<action expression="#{roomBooking.bookRoom}" />
</transition>
<transition name="back" to="payment" />
<transition name="cancel" to="cancelPage" />
</page>
<page name="confirmation" view-id="/reservations/complete.xhtml"
no-conversation-view-id="/reservations/preferences.xhtml">
<redirect />
<end-conversation />
</page>
<page name="cancelPage" view-id="/home.xhtml"
no-conversation-view-id="/home.xhtml">
<redirect />
<end-conversation />
</page>
</pageflow-definition>The diagram is here:
