Jason Porter resolved SEAMFACES-208.
------------------------------------
Assignee: Jason Porter
Resolution: Done
> Support for resolving no argument methods in an EL value expression
> -------------------------------------------------------------------
>
> Key: SEAMFACES-208
> URL: https://issues.jboss.org/browse/SEAMFACES-208
> Project: Seam Faces
> Issue Type: Feature Request
> Components: CDI Integration
> Affects Versions: 3.1.0.Beta2
> Reporter: Dan Allen
> Assignee: Jason Porter
> Fix For: 3.1.0.Final
>
>
> The EL specification added support for resolving parameterized methods in
> value and method expressions, with one exception. It does not support
> resolving methods with 0 parameters. The reason is that an () used at the end
> of a property is not acknowledged. As a result, the resolver attempts to
> resolve the method name as a bean property.
> For example, assume we have the method:
> {code}
> public Integer count() {
> return 1;
> }
> {code}
> If we attempt to resolve this in a value expression using:
> {code}
> #{bean.count()}
> {code}
> We can an error message "count property not found on bean"
> It works as expected if the method has at least one parameter:
> {code}
> public Integer count(Integer i) {
> return i;
> }
> {code}
> The following expression will resolve to a value of 1.
> {code}
> #{bean.count(1)}
> {code}
> This also breaks resolving the size of a collection:
> {code}
> #{employees.size()}
> {code}
> In this case, the error is a bit strange because it tries to parse size as an
> index.
> The root cause of all this is that the spec does not properly honor 0
> parameters as a valid number of parameters for a parameterized methods.
> Instead, it ignores the () and treats the expression as a property.
> Method expressions does not have this limitation since both .action and
> .action() are equivalent expressions.
