Hello,
I'm wondering if there is a simple way to bind a model property to a component attribute.
Here is a simple example :
I would like to persist the selectManyCheckbox layout attribute. In the model I would typically use an enum (independent of the UI values) like
enum Alignment { HORIZONTAL, VERTICAL }and expect to use it this way
<h:selectManyCheckbox layout="#{myBean.alignment}" ...>where getAlignment in myBean return an Alignment object.
Obviously we need to define somewhere conversions rules which are pretty straightforward : Alignment.HORIZONTAL -> "lineDirection" etc ...
The ValueExpression mechanism call ELResolver to get myBean.alignment but then coerce the enum to a String by calling the name() method (as defined in the unified EL spec), which of course doesn't work.
I'm using Seam so I don't want to write a backed bean just to convert this value.
I though to write an EL function but it's supposed to be a view stuff isn't it ?
Any idea ?
Thanks,
Bruno
