TAP5-2615: If component now has an optional 'then' block parameter
> "If" component should have an optional "then" parameter
> -------------------------------------------------------
>
> Key: TAP5-2615
> URL: https://issues.apache.org/jira/browse/TAP5-2615
> Project: Tapestry 5
> Issue Type: Improvement
> Components: tapestry-core
> Reporter: Thiago H. de Paula Figueiredo
> Priority: Minor
>
> Right now, if you use {{If}} and have a {{then}} parameter, the template
> looks odd, since {{else}} isn't in the same nesting and indentation level as
> the {{then}} part. Example:
> {code}
> <t:if test="something">
> something is true
> <p:else>
> something is false
> </p:else>
> <t:if>
> {code}
> A {{then}} parameter would allow everything to be in the same nesting and
> indentation level. Example:
> {code}
> <t:if test="something">
> <p:then>
> something is true
> </p:then>
> <p:else>
> something is false
> </p:else>
> <t:if>
> {code}
> If {{then}} is missing, everything works as in the past (if test is true,
> render the body of the If except for the {{else}} block; otherwise, render
> the {{else}} block). If {{then}} is present, everything outside {{then}} and
> {{else}} won't appear regardless of the test being true or false.
> {{else}} should also be present in the {{Unless}} component, since it and
> {{If}} have almost all their logic inherited from {{AbstractConditional}},
> their superclass.
