> Key: TAPESTRY-1694
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1694
> Project: Tapestry
> Issue Type: Wish
> Components: Framework
> Affects Versions: 4.1.2
> Reporter: Kevin Menard
>
> Nowadays, I store most properties right in the page class. There's typically
> little reason to store them in the page spec. For temporary variables,
> however, such as "value" used in the For component, I tend to put them in the
> page spec. The reason is simply that the getters and/or setters would never
> actually be accessed if they were in the page class and this makes static
> anaylzers go nuts. The result is someone invariably removes the method
> thinking it's no longer needed and then the page breaks.
> What I would like to see is either a new binding or a new attribute.
> Tapestry would then auto-enhance the page as if the property were defined in
> the page spec.
> As an example, the following:
> page spec:
> <page-specification class="...">
> <property name="blah"/>
> </page-specification>
> template:
> <span jwcid="@For" source="ognl:someSource" value="ognl:blah">
> ...
> </span>
> would reduce to one of the following:
> <span jwcid="@For" source="ognl:someSource" value="temp:blah">
> ...
> </span>
> or
> <span jwcid="@For" source="ognl:someSource" temp="ognl:blah">
> ...
> </span>
> In these latter cases, nothing needs to be added to the page spec. "blah" is
> just a name given to the current element in the iteration.
