> Support Freemarker template_exception_handler=rethrow
> -----------------------------------------------------
>
> Key: WW-1808
> URL: https://issues.apache.org/struts/browse/WW-1808
> Project: Struts 2
> Issue Type: Improvement
> Components: Views
> Affects Versions: 2.0.6
> Reporter: Jasper Rosenberg
> Priority: Minor
> Fix For: 2.1.0
>
>
> 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);
> }
