Description

With the following code, the markup builder will recognize a call to the each method, but at runtime, it throws an error:

MarkupTemplateEngine engine = new MarkupTemplateEngine(new TemplateConfiguration())

        def template = engine.createTemplate '''
            groups.each { k, v -> li(k) }
        '''
        def model = [groups:[a:'Group a',b:'Group b']]
        String rendered = template.make(model)

The error is:

groovy.lang.MissingMethodException: No signature of method: GeneratedMarkupTemplate0$_run_closure1.doCall() is applicable for argument types: (java.util.LinkedHashMap$Entry) values: [a=Group a]
Possible solutions: doCall(java.lang.Object, java.lang.Object), findAll(), findAll(), isCase(java.lang.Object), isCase(java.lang.Object)
