Subject [jira] Commented: (WW-1808) Support Freemarker template_exception_handler=rethrow

Martin Gilday commented on WW-1808:
-----------------------------------

Ah I see.  Sorry Jasper, I didn't see where writeCompleted was set.  Kind of obvious now I
read it again.  Have you investigated if it is possible to have the param set based on what
is set in freemarker.properties to avoid the duplication in xwork.xml/struts.xml ?

> If you set in freemarker.properties, the property:
> template_exception_handler=rethrow
> Then you do not want the FreemarkerResult to output to the Writer unless you know the
template processed cleanly (so you can handle the exception and go to a nice error page rather
than being stuck with half rendered template output).
> My suggestion is to add a new parameter to FreemarkerResult, something like "writeCompleted"
which defaults to false and, if true, renders the template into a String buffer, writing the
result to the actual Writer only if it succeeded.
> Something like:
> // Process the template
> Writer writer = getWriter();
> if (getWriteCompleted()) {
>     CharArrayWriter charArrayWriter = new CharArrayWriter();
>     template.process(model, charArrayWriter);
>     charArrayWriter.flush();
>     charArrayWriter.writeTo(writer);
> } else {
>     template.process(model, writer);
> }
