AttributeError: 'ZopeContext' object has no attribute 'getCompilerError'
TALGenerator.__init__() expects to have in its expressionCompiler parameter an zope.tal.interfaces.ITALExpressionCompiler instance that has getCompilerError() method.
Instead of that zope.pagetemplate.pagetemplate.PageTemplate.pt_render() passes down along the chain an instance of Products.PageTemplates.Expressions.ZopeContext class, which implements ITALExpressionEngine. From zope.pagetemplate-3.5.2-py2.7.egg/zope/pagetemplate/pagetemplate.py:110

Without this /very useful/ combination of "tal:attribuites", "tal:replace" and "structure" interpretation goes into another branch of zope.tal.interpreter.do_insertStructure_tal(), that doesn't use TALGenerator and hence doesn't fail. I thank our bright developers for revealing this.

As a workaround try to remove the tal:attributes. Since tal:replace will replace the entire tag, the attributes call is a bit useless. But http://
