[Tapestry Beginner] Validation is ignored
Hi Everyone,
i've been teaching myself tapestry for some time now, and everytime i think
i am finally getting a grip on it something new comes up.
OK, here's the deal... (i'll be using snippets since you guys probably don't
want a million lines of code... all code i post compiles in it's context and
runs without exceptions)
i have to pages, Login and Register
First for login:
Login.html has:
tr
tdlabel jwcid=@FieldLabel field=component:usernameUser
Name/label/td
tdinput jwcid=username//td
/tr
Login.page has:
bean name=ValidString class=myproject.Validator.ValidString /
component id=username type=TextField
binding name=value value=username/
binding name=validators value=validators:required,$ValidString /
binding name=displayName value=message:username /
/component
Login.java has:
public abstract String getUsername();
public abstract void setUsername(String Username);
public IPage tryLogin(){ // -- gets called when the form around username
is submitted
//do fancy stuff
}
this works quite good. it checks the enteresd string in username against the
self written Validator $ValidString. I can debug, breakpoint, step-though
and see all the magic happening. quite cool, acctually.
Now for Register
Register.html
trtdfirstname /tdtdinput type=text jwcid=firstname
//td/tr
trtdlastname /tdtdinput type=text jwcid=lastname
//td/tr
Register.page
bean name=ValidString class=myproject.Validator.ValidString / !--
same validator as before --
!-- Form --
component id=register type=Form
binding name=listener value=listener:tryUserCreate/
/component
component id=submitRegister type=Submit
/component
!-- Attributes of a Person --
component id=firstname type=TextField
binding name=value value=firstname/
binding name=validators value=validators:required,$ehfgbiasdbgujas
/ !-- NOTE THIS --
/component
component id=lastname type=TextField
binding name=value value=lastname/
binding name=validators value=validators:required,$ValidString /
/component
Register.java
public abstract String getFirstname();
public abstract String getLastname();
public IPage tryUserCreate(){
// do more fancy stuff
}
now this acctually compiles and runs (!!!) without an error or expection
even tho the gibberish Validator bean in firstname does not exist. This form
has a lot more fields to it, and two more self written validators but this
is pretty much the essence.
now - the Validators here get ignored. i can write anything after the $ and
it still runs through without any trouble. I can even delete the bean
statement completely withouth raising an exception.
required is also ignored - it jumps right into the listener without looking
at the Validators.
This started happening after i had to refactor the class to move it to
another package. Used the NetBeans refactor (which always worked before) and
suddenly it would not validate anymore. Refactoring it back does not help
either.
if i type somthing like this in one if the TextFields it does give me an
exception upon loading the page:
binding name=validators value=validators:required,fsgdsfghkjsn /
Here is what i have tried:
i have moved the Form around in register - even used it inline - same thing
i have copied and pasted the content to a new file - same thing
i have used tapestry 4.1.1, 4.1.2 and the nightly 4.1.3 - same thing
i have deleted the project and reloaded it from svn - same thing
i have set up NetBeans completely new - same thing
i have run the application on two more machines (Windows, Debian, Ubuntu) -
same thing
i have run it with sun java 1.5 and 1.6 - same thing
also, if i tried to use a Fieldlabel (maybe thats the error ?) and copied
the username from Login to Register (it has a username too) - one to one
copy - works in Login, not in Register (the Fieldlabel says no DisplayName
was set in Username - which i definetly had set - and throws an expception)
anybody got any idea why the validators get ignored or why Register is
behaving to strange ? i really need this to work sometime soon...
Hope this mail is not too cryptic,
Ingmar

Re: [Tapestry Beginner] Validation is ignored
I can't really see your mistake from the code, but anyway, here are
two things that could be wrong:
1. for client-side validation to work, you need to set the
clienValidationEnabled parameter of your form to true
2. be sure to bind the form's delegate-parameter to your delegate.
3. if you want server-side validation check the delegate bean using hasErrors

This is not what i would have expected to happen - but it did happen, and it confused me greatly. Using the SubmitType submit and success listener now gets it all working nicely even with the self written validators. again, thanks for the answer - i think the issue at hand is resolved... -- View this message in context: http://www.nabble.com/-Tapestry-Beginner--Validation-is-ignored-tf4278261.html#a12189234 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
