Errata for Programming Groovy

#32254: "Here's an example: friends refers to a map"

Friends is a list, not a map. Also, the short names in the list definition (e.g. briang) are never used.

#36280: The code works with 1.5.6, JVM: 1.5.0_17-b04 on Ubuntu 8.10
I haven't found a jvm that works with Groovy 1.5.7. If I use 1.5.7 to run UsingDOMCategory.groovy I get
Caught: java.lang.StackOverflowError

The languages.xml file in the code download differs from the example in the book on page 148. The xml file in the book works fine, but the one in the download returns empty results.

#32015: The code:
langs = ['C++' : 'Stroustrup' , 'Java' : 'Gosling' , 'Lisp' : 'McCarthy' ]
xmlDocument = new groovy.xml.StreamingMarkupBuilder().bind {
mkp.xmlDeclaration()
mkp.declareNamespace(computer: "Computer" )
languages {
comment << "Created using StreamingMarkupBuilder"
langs.each { key, value ->
computer.language(name: key) {
author (value)
}
}
}
}
println xmlDocument

Does not produce an indented xml document, but a single line string. This is really important to mention and confusing. I don't think there is a way to make the output indented with that Builder.--Fred Janon
