Access to block parameters
--------------------------
Key: TAPESTRY-1623
URL: https://issues.apache.org/jira/browse/TAPESTRY-1623
Project: Tapestry
Issue Type: New Feature
Components: tapestry-core
Affects Versions: 5.0.5
Reporter: Dan Adams
Fix For: 5.0.6
One of the features I used in T4 which made it very powerful was the ability to
pass informal parameters to a Block and then get them from within the block.
BeanEditForm demonstrates making a context available to blocks via an
environmental interface but this seems like too much overhead for less formally
defined situations. Perhaps it could look something like this:
<t:delegate to="block:myblock" foo="bar" />
<t:block id="myblock">
${context.parameters.bar}
</t:block>
in the class:
@Environment
private BlockContext context;
the interface:
public interface BlockContext {
Map<String, Object> getParameters();
}
This would also required being able to do more OGNL-like expressions.
