[stringtemplate-interest] Working on ST4 ObjC runtime

[Alan Condit]

I am working on TestGroup and I am currently passing 31 of the first 32 tests so I must be getting close but currently have a problem with this test:
	@Test public void testSubdirWithSubtemplate() throws Exception {
		// /randomdir/a and /randomdir/subdir/b
		String dir = getRandomDir();
		writeFile(dir+"/subdir", "a.st", "a(x) ::= \"<x:{y|<y>}>\"");
		STGroup group = new STGroupDir(dir);
		ST st = group.getInstanceOf("/subdir/a");
		st.add("x", new String[] {"a", "b"});
		assertEquals("ab", st.render());
	}

In interpreter when it accesses the _sub1 template, st.impl.formalArguments is null so it is not copying over the st.locals and as a result generates no output.

I have looked at my code and the original java code, I can't see where I am going wrong.
It looks like st.locals should be propagated in Interpreter in setFirstArgument but when I get there both st.impl.formalArguments  and st.locals are nil. I can't figure out where st.impl.formalArguments is supposed to be set.

Can anybody give me a clue where to look?

Thanks,
Alan
