Re: Textfield validation problem

2006-10-14 Thread Ryan Holmes 

Change this:

binding name=translator value=translator:number,pattern=#.#/

to this:

binding name=translator  
value=translator:number,pattern=#.#,omitZero=false/


The 'omitZero' property in  
org.apache.tapestry.form.translator.NumberTranslator is true by  
default. Paul Ferraro (who I believe contributed much of the  
translation and validation system for Tap 4.0) argues that omitZero  
should be false by default in this JIRA issue:

http://issues.apache.org/jira/browse/TAPESTRY-633

So vote for it if you agree.

Re: Textfield validation problem

Ryan,

Hello again. Is it possible to use a regular expression with a
textfield? I don't want to use it to read a number, but a string.

Thanks

Re: Textfield validation problem

2006-10-14 Thread Ryan Holmes 
Sure, sounds like you want a numeric-only string. Tapestry has a  
Pattern validator, but I don't know if you can specify the pattern  
inside your 'validators:' value. I always set up pattern validators  
as beans and then reference them in the 'validators:' value, like so:


  bean name=numericValidator
class=org.apache.tapestry.form.validator.Pattern  
lifecycle=page

set name=pattern'^[0-9]+$'/set
set name=message value=message:invalid-numeric-input /
  /bean

  component id=numericStringField type=TextField
binding name=value value=myNumericString /
binding name=displayName value=message:my-numeric-string- 
label /
binding name=validators value=validators:required, 
$numericValidator /

  /component

I'm using the '$' syntax to reference a bean in the 'validators:'  
value. Note that I'm using localizable message keys, but you can of  
course use literal strings for your messages. Also note that I'm  
setting 'lifecycle=page' in the bean definition. This should give  
slightly better performance by causing the bean to be instantiated  
only once, rather than on each page render.


One more thing -- since this TextField represents a String value, you  
don't need to specify a translator unless you want to change the  
default string translation behavior (you probably already knew that).
