[jira] Commented: (TAPESTRY-937) Custom binding prefixes shorter
than 2 characters fail without useful diagnostics
[ http://issues.apache.org/jira/browse/TAPESTRY-937?page=comments#action_12378343 ]
Paul Cantrell commented on TAPESTRY-937:
----------------------------------------
A typo in the above, in paragraph 2:
":bar" should be equivalent to "component:bar"
...should read:
":bar" should be equivalent to "ognl:bar"
> Custom binding prefixes shorter than 2 characters fail without useful diagnostics
> ---------------------------------------------------------------------------------
>
> Key: TAPESTRY-937
> URL: http://issues.apache.org/jira/browse/TAPESTRY-937
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0.1
> Environment: Java 1.5, OS X 10.4.6
> Reporter: Paul Cantrell
>
> It should be possible to specify custom binding prefixes consisting of one character, or even of the empty string, e.g.:
> <contribution configuration-id="tapestry.bindings.BindingFactories">
> <binding prefix="" service-id="tapestry.bindings.OGNLBindingFactory"/>
> <binding prefix="C" service-id="tapestry.bindings.ComponentBindingFactory"/>
> </contribution>
> This configuration should cause "C:foo" to be equivalent to "component:foo", and ":bar" to be equivalent to "component:bar". However, Tapestry silently ignores prefixes shorter than two characters, treating "C:foo" as a literal even with the above configuration.
> Tapestry should do one of two things:
> (1) Hopefully this behavior is unintentional. If so, it is due to a dropped minus sign on line 63 of BindingSourceImpl:
> if (colonx > 1)
>
> ...should be:
> if (colonx > -1)
> (2) If this behavior is intentional, BindingSourceImpl should reject any invalid contributions up front instead of ignoring them.
