Most tapestry folk will agree that putting logic in your templates
makes them brittle and hard to maintain, but sometimes need a little
something in the template. I created a simple utility binding to help
out in these kinds of situations.
Example usage:
Why | ? because : isn't valid in the text of a binding, or wasn't at
the time I wrote this.
import org.apache.tapestry5.Binding;
import org.apache.tapestry5.BindingConstants;
import org.apache.tapestry5.ComponentResources;
import org.apache.tapestry5.internal.bindings.AbstractBinding;
import org.apache.tapestry5.ioc.Location;
import org.apache.tapestry5.services.BindingFactory;
import org.apache.tapestry5.services.BindingSource;
/**
* Implementation of the if: binding prefix
* default binding is literal, other bindings can be used by
specifying prefix.
* example: "if:prop?selected|prop:x"
*/
public class IfBindingFactory implements BindingFactory {
private final BindingSource _bindingSource;
public IfBindingFactory(BindingSource source) {
this._bindingSource = source;
}
public Binding newBinding(String description, ComponentResources
container, ComponentResources component,
String expression, Location location) {
final String[] p1 = expression.split("\\?", 2);
final String[] p2 = p1[1].split("\\|", 2);
Object testBinding = _bindingSource.newBinding(description,
container, component, BindingConstants.PROP, p1[0], location);
Object trueBinding = p2[0];
if (p2[0].length() > 0) {
trueBinding = _bindingSource.newBinding(description,
container, component, BindingConstants.LITERAL, p2[0], location);
}
Object falseBinding = "";
if (p2.length == 2 && p2[1].length() > 0) {
falseBinding = _bindingSource.newBinding(description,
container, component, BindingConstants.LITERAL, p2[1], location);
}
return new IfBinding(testBinding, trueBinding, falseBinding);
}
public class IfBinding extends AbstractBinding {
private Object _test;
private Object _true;
private Object _false;
public IfBinding(Object testBinding, Object trueBinding,
Object falseBinding) {
_test = testBinding;
_true = trueBinding;
_false = falseBinding;
}
public Object get() {
final Object o = get(_test);
if (o instanceof Boolean) {
return o.equals(true) ? get(_true) : get(_false);
}
return o == null ? get(_false) : get(_true);
}
@Override
public boolean isInvariant() {
return false;
}
@Override
public Class getBindingType() {
return Object.class;
}
private Object get(Object o) {
if (o instanceof Binding) {
return ((Binding) o).get();
}
return o;
}

Hi Thiago,
thanks for the quick reply, I'd already seen the official tapestry
property expressions page but as there's no examples given there I was
hoping there was something else buried in one of the wiki pages?

to have a lot of helper methods for the logic that was attached to the
various fields on my form, but I guess I can't be avoided.

Re: property expressions
In Tapestry 4, we shifted a lot of logic into OGNL because that was
the only logic that could be reloaded (with the template) at runtime,
during development. This was good in some ways, OGNL is still more
versatile than Tapestry 5's property expressions, but came at a huge
cost in terms of reflection overhead and a few highly contested code
paths that tended to serialize the application.
In Tapestry 5, you tend to reference a property from your template, as
Thiago pointed out. Both the template and the Java code reload
instantly, and the separation makes each part a bit cleaner.

What do you mean by "to update these expression to work with ANTLR"? I'm
not following you. And don't forget that you can add your own binding
implementations in Tapestry. prop (property expressions) is just one of
them.
Easy:
public String getSurnameCssClass() {
return surname == > null ? 'touch-and-type' : '';
}
Logic should be on Java classes, not templates. That's the Tapestry 5
philosophy (MVC's too).

Hi all,
just a quick question, looking at the property expressions guide @
http://tapestry.apache.org/tapestry5/guide/propexp.html it looks like I
should be able to evaluate whether a property has a null value (handy
for if conditions) without having to use ognl,
e.g. instead of
${message:EXPORT}
I should be able to use the property expression directly, there's a null
keyword and an notOpt !, but what is the proper synthax?

Re: T5.1 Property Expressions
Have you tried ${getTitle('false')}?

T5.1 Property Expressions
I just tried out the new T5.1 property expressions for the first time and got
an error. I’m trying to replace this:
${linkTitle}
public String getLinkTitle() {
return getTitle(false);
}
With this:
${getTitle(false)}
Which I should be able to do according to the Grammar as far as I can see,
since but I get this error when I try it:
Caused by:
org.apache.tapestry5.internal.services.PropertyExpressionException: Node
false (within expression 'getTitle(false)') was type FALSE, but was expected
to be (one of) DECIMAL, DEREF, IDENTIFIER, INTEGER, INVOKE, LIST, SAFEDEREF,
