Re: java.lang.Boolean undefined

Hi,

Thanks all for your help.

Just in case there is anyone else looking for the same information I
have included a set of tests and just thought I would outline my
requirements for what I wanted to do.

Basically we have an inheritance hierarchy when a method exists on a
certain object, populate a value when one does not exist just leave an
empty string effectively leaving a no value, so basically taking an
inheritance hierarchy and converting it to a flat structure. I settled
on the following syntax for dealing with java.lang.Boolean values.

<#if (model.isObjectBoolean())?has_content>${model.isObjectBoolean()}?string}</#if>

The line  (model.isObjectBoolean()) catches the operation if method
does not exist.

If anyone has any improvements on how I can represent this better
please do let me know.

Cheers
Ben
