Question

How can I make a tag that makes a select field out of a Java enum for the Play! framework? I’ve tried to see how the CRUD module does it but there’s too many abstraction layers that I don’t really understand yet.

If you fully qualify the Enum in the tag then you don’t need to place it in RenderArgs.

Your tag StatusSelect.html:

<select name="status">
    #{list com.something.StatusEnum.values(), as:'status'}
        <option>${status}</option>
    #{/list}
</select>

And called from the page:

#{StatusSelect /}

You could then add complexity to it by specifying a “name” attribute and other features eg:

<select id="${_id}" name="${_name}" class="${_class}">
    #{list com.something.StatusEnum.values(), as:'status'}
        <option>${status}</option>
    #{/list}
</select>

And the new page tag:

#{StatusSelect id:'status1', name:'status', class:'bold'/}
