Answer 1

I've managed it now using ${pageScope.getProperty(...)}.

Answer 2

There's no 'model' scope or variable. Instead objects in the model map are set as Request attributes to make them available to the GSP. This is a Spring feature which makes it easy to access variables in JSPs using JSTL and since the GSP syntax is very similar to JSTL it works the same way in Grails.

So you can use this:

${request.getAttribute('item'+i)}

to access model variables using dynamic names.

Answer 3

You can use ${fieldValue(bean: book, field: 'title')}
