Template.execute()

[Paul Brady <pa...@macalla.com>]

Hi,
 I am attempting to execute a template from inside an extension element. I
do the following:

QName qTemplateName = new QName(strTemplateName);

ElemTemplate template =
xslprocessorcontext.getStylesheet().getStylesheetRoot().getTemplateComposed(
qTemplateName);
template.execute(xslprocessorcontext.getTransformer());

I get the following exception when template.execute() is called:
java.lang.reflect.InvocationTargetException:
java.lang.ArrayIndexOutOfBoundsException: 20 >= 1

Is there some extra setup I need to do before I call template.execute()? Am
I doing something else wrong?

Any help appreciated.
Paul.
