ConditionalProperties

[Gal Dolber]

Hi,

Is this working already? http://code.google.com/p/google-web-toolkit/wiki/ConditionalProperties

<define-property name="mobile.user.agent" values="android, iphone, not_mobile" />


<property-provider name="mobile.user.agent"><![CDATA[


  {
    var ua = window.navigator.userAgent.toLowerCase();
    if (ua.indexOf('android') != -1) { return 'android'; }
    if (ua.indexOf('iphone') != -1) { return 'iphone'; }
    return 'not_mobile';


  }
]]></property-provider>

<!-- Constrain the value for non-webkit browsers -->


<set-property name="mobile.user.agent" value="not_mobile" >


  <none> <!-- Actually means NOR, in this case "not safari" -->


    <when-property-is name="user.agent" value="safari" />


  </none>
</set-property>

I made a small project example but when I compile it I get only 6 permutations, when I should get 8? (5 other browsers + (safari * mobile.user.agent))? the documentation says that this example should generate 9 permutations...

I am testing with gwt trunk compiled yesterday.

What am I doing wrong?

Thanks in advnc

nobody?

It is working. Apache Wave uses it. I believe I successfully used it too.

Have a look at the top of the generated symbolMaps files, they'll tell you which deferred binding property leads to a particular permutation, along with its value.

Thanks!

I still don't understand what I am doing wrong. I even can't get working a normal selection property.

{{{

<define-property name="my.property" values="default" />

<property-provider name="my.property" generator="com.myPropertyGenerator" />

<extend-property name="my.property" values="value1, value2" />

<set-property-fallback name="my.property" value="default" />
}}}

Shouldn't this be enough to get an extra 12 permutation (18 in total)? I am getting only 6

Could it be that GWT optimizes the case where the property isn't used in any <generate-with> or <replace-with> rule?

[Gal Dolber]

Yes, I though that, but then I saw the i18n "locale" property, that is the most similar to the one I am trying to do and It doesn't use <when-property-is>

<generate-with class="com.google.gwt.i18n.rebind.LocalizableGenerator">

    <when-type-assignable class="com.google.gwt.i18n.shared.Localizable" />

  </generate-with>
