BasePage doesn't have an emailAddress property. You need to make sure Tapestry knows how to find your page class.
-----Original Message----- From: Ken nashua [mailto:[EMAIL PROTECTED] Sent: Friday, October 13, 2006 8:18 AM To: [email protected] Subject: BindException whoas... Tap-4.1 help please (thanks) Guys, I am whipping up a simple Login page... no *.page files just annotations. The page displays and the validators are nice. If someone could bail me out here I would be greatful. The Login.html quits on trying to render the OGNL for emailAddress. OGNL is having trouble getting to this object (Person object persisted and created during onrender) I am kinda blue in the face... Do you see anything in my code preventing the html from retrieving this property? What am I missing? Thanks so much. Here is the exception... org.apache.tapestry.BindingException Unable to read OGNL expression '<parsed OGNL expression>' of [EMAIL PROTECTED]: $BasePage_4.emailAddress binding: ExpressionBinding[Login emailAddress] Thanks in advance -------- Login.html code follows ---- <html jwcid="@Shell" title="message:page.title"> <body jwcid="@Body"> <h1><span jwcid="@Insert" value="message:page.title"/></h1> <DEFANGED_form jwcid="[EMAIL PROTECTED]" success="listener:onFormSubmit" cancel="listener:onFormCancel" clientValidationEnabled="ognl:true" > <table border="0"> <tr> <td> <span jwcid="@Insert" value="message:label.emailAddress">EmailAddress:</span> </td> <td><input jwcid="[EMAIL PROTECTED]" value="ognl:emailAddress" validators="validators:required" displayName="message:label.emailAddress" size="40" /></td> </tr> <tr> <td> <span jwcid="@Insert" value="message:label.password">Password:</span> </td> <td><input jwcid="[EMAIL PROTECTED]" value="password" validators="validators:required" displayName="message:label.password" size="40"/></td> </tr> <tr> <td/> <td> <input type="submit" jwcid="[EMAIL PROTECTED]" label="message:label.login" /> <input type="submit" jwcid="[EMAIL PROTECTED]" label="message:label.cancel" onclick="DEFANGED_javascript:this.form.events.cancel();" /> </td> </tr> <tr> <td/> <td> <span jwcid="@Insert" value="message:label.rememberMe"/> <input jwcid="[EMAIL PROTECTED]" value="rememberMe"/> </td> </tr> </table> </form> <p><a href="#" jwcid="@PageLink" page="Home">Home</a></p> </body> </html> -------- Login.java ----- package proto;
