Rory,
I think you can have a look at the source.
I have two different version of warp-core:
earlier version:(line 36)
writer.elementWithAttrs("textarea", new Object[] { "id", id, "name", bind }, attributes);
later version:(line 34~36)

        writer.elementWithAttrs("textarea",
                ComponentSupport.getTagAttributesExcept(new Object[] { "id", id, "name", bind }, attribs, "name"));
        writer.writeRaw(Expressions.evaluate(bind, context.getContextVars()).toString());

So, why don't you add 'name' property to get over it? :)

I use the later version
I found
Expressions.evaluate(bind, context.getContextVars())
this is null.
before the
writer.writeRaw(Expressions.evaluate(bind, context.getContextVars()).toString());
the writer's context is fine.
