In tap3, you could use the
ValidField
and give it a double (or something else) validator...
Here's the code (for the .jwc):
<bean name="double"
class="org.apache.tapestry.valid.NumberValidator"
lifecycle="page">
<set-property name="valueTypeClass"
expression="@[EMAIL PROTECTED]"/>
<set-property name="required" expression="false"/>
<set-property name="clientScriptingEnabled" expression="true"/>
</bean>
<component id="inputDiameter" type="ValidField">
<message-binding name="displayName" key="diameterLabel"/>
<binding name="value" expression="monument.diameter"/>
<binding name="validator" expression="beans.double"/>
</component>

The thing I miss most is a java problem: dynamic class
reloading (HotSwap sucks badly). This makes me look at
Ruby on Rails enviously.
Spindle support is missing not so much when you use
annotations in my opinion as the compiler is able to do
more validations in that case.

Yes, I see that. What prevents me from moving right now is mainly the lack
of spindle-support and the migration-expenses and (somewhat) the
reportedly
slow startup in dev.

You should take a look at @TextField in T4. It got a _lot_ better.
especially you can now specify a numeric format pattern.
e.g.
<input type="text" jwcid="testInputField" displayName="Wert"
translator="translator:number, pattern=0.00"
validators="validators:required, maxLength=10" />

I use @contrib:NumericField for numbers - that's anyway
nicer - for checks
and such

Subject: Editing int/Integer in a TextField component
For T3
I have run into a problem I didn't except to run into.
I have an object with a property of type int, which I would
like to edit
in a TextField on my page. But I get the following error:
"Parameter value (2) is an instance of java.lang.Integer,
which does not
inherit from java.lang.String."
Is there a solution for this, or do I have to provide a
new field of
type String, that I convert myself? I would not like to do
this, since
it would force me into a less clean solution.
Inge
