A macro operates in the context in which it is defined. However, a nested block within a macro instruction is defined in the context in which the macro was invoked. So, we actually need to temporarily switch the namespace and macro context back to what it was before macro invocation to implement this properly. I (JR) realized this thanks to some incisive comments from Daniel Dekany. getBodyParameters List getBodyParameters()(Code) getCanonicalForm public String getCanonicalForm()(Code) getDescription public String getDescription()(Code) Fields inherited from freemarker.core.TemplateElement TemplateElement nestedBlock(Code)(Java Doc) List nestedElements(Code)(Java Doc) TemplateElement parent(Code)(Java Doc) Methods inherited from freemarker.core.TemplateElement abstract void accept(Environment env) throws TemplateException, IOException(Code)(Java Doc) public Enumeration children()(Code)(Java Doc) public boolean getAllowsChildren()(Code)(Java Doc) public TreeNode getChildAt(int index)(Code)(Java Doc) public int getChildCount()(Code)(Java Doc) public TemplateSequenceModel getChildNodes()(Code)(Java Doc) abstract public String getDescription()(Code)(Java Doc) public int getIndex(TreeNode node)(Code)(Java Doc) public String getNodeName()(Code)(Java Doc) public String getNodeNamespace()(Code)(Java Doc) public String getNodeType()(Code)(Java Doc) public TreeNode getParent()(Code)(Java Doc) public TemplateNodeModel getParentNode()(Code)(Java Doc) boolean heedsOpeningWhitespace()(Code)(Java Doc) boolean heedsTrailingWhitespace()(Code)(Java Doc) boolean isIgnorable()(Code)(Java Doc) public boolean isLeaf()(Code)(Java Doc) TemplateElement nextSibling()(Code)(Java Doc) TemplateElement nextTerminalNode()(Code)(Java Doc) TemplateElement postParseCleanup(boolean stripWhitespace) throws ParseException(Code)(Java Doc) TemplateElement prevTerminalNode()(Code)(Java Doc) TemplateElement previousSibling()(Code)(Java Doc) public void setChildAt(int index, TemplateElement element)(Code)(Java Doc) void setParentRecursively(TemplateElement parent)(Code)(Java Doc) Fields inherited from freemarker.core.TemplateObject int beginColumnbeginLineendColumnendLine(Code)(Java Doc) Methods inherited from freemarker.core.TemplateObject static void assertNonNull(TemplateModel model, Expression exp, Environment env) throws InvalidReferenceException(Code)(Java Doc) public boolean contains(int column, int line)(Code)(Java Doc) TemplateObject copyLocationFrom(TemplateObject from)(Code)(Java Doc) final public int getBeginColumn()(Code)(Java Doc) final public int getBeginLine()(Code)(Java Doc) abstract public String getCanonicalForm()(Code)(Java Doc) final public int getEndColumn()(Code)(Java Doc) final public int getEndLine()(Code)(Java Doc) public String getEndLocation()(Code)(Java Doc) final public String getSource()(Code)(Java Doc) public String getStartLocation()(Code)(Java Doc) public Template getTemplate()(Code)(Java Doc) static TemplateException invalidTypeException(TemplateModel model, Expression exp, Environment env, String expected) throws TemplateException(Code)(Java Doc) final void setLocation(Template template, Token begin, Token end) throws ParseException(Code)(Java Doc) final void setLocation(Template template, Token begin, TemplateObject end) throws ParseException(Code)(Java Doc) final void setLocation(Template template, TemplateObject begin, Token end) throws ParseException(Code)(Java Doc) final void setLocation(Template template, TemplateObject begin, TemplateObject end) throws ParseException(Code)(Java Doc) void setLocation(Template template, int beginColumn, int beginLine, int endColumn, int endLine) throws ParseException(Code)(Java Doc) public String toString()(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
