    copied!<p>I am trying to develop a component where a signature is requiered from a user to complete a certain operation here is the sequence:</p> <ol> <li>User clicks on a commandButton or commandLink.</li> <li>A popup opens requesting the user to enter the username/password</li> <li>If the user enters the correct username/password the original action is executed.</li> <li>If the user enters the wrong username/password or clicks the cancel button nothing happens.</li> <li>Finally when the action is really executed the signature information should be available.</li> </ol> <p>Note: the solution should be a composite component that should have the following structure:</p> <pre><code>&lt;myCC:confirm action="#{testMB.delete}" singatureType="deleteObject"/&gt; </code></pre> <p>What I did to implement this behavior is:</p> <ol> <li><p>Created a view scoped managed bean <strong>SignatureMB</strong> to handle the signature with the properties (username, password, and signatureType)</p></li> <li><p>Created a request scoped managed bean <strong>#{testMB}</strong> with a managed property mapped to the <strong>#{signatureMB}</strong></p></li> <li><p>in my composite component <strong>myCC:confirm</strong> I created two links an outputLink that will open a popup with the signature form, the second is a hidden commandLink that will contain the real action to submit i.e. <strong>#{testMB.delete}</strong></p></li> <li><p>The signature form is posted and if the username/password are correct the popup will close itself and trigger the click event of the hidden commandLink.</p></li> <li><p>Finally in the <strong>#{testMB.delete}</strong> I will have the signature information, and be able to process the information and when done I will reset the values in the <strong>signatureMB</strong>.</p></li> </ol> <p>What do you think about this implementation? do you think there is a better way to do it? </p>
