BTW, I was not able to reproduce the issue in a simple test app
using Grails 1.3.7.
// TestController.groovy
package test.xyz
class TestController {
def index = {
//def entity = new Node(params) // entity is def'd, so local scope
//if(entity.save(flush:true)) {
def entity = new Object()
if (true) {
withFormat {
println entity // works, toString() invoked
html {
println entity // error, java.lang.NoSuchMethodError
(at withFormat & html lines)
}
}
}
}
}
Then I accessed
http://localhost:8080/test-xyz/test/index And I got the following output
java.lang.Object@1786b2ca
java.lang.Object@1786b2ca
This Groovy script is also producing the same result:

Best regards,
Daniel.
