Observing some strange behaviour in our code thats is pulling back published page content from broker.

This is DD4T (except we use WCFs a DD4T providers to get stuff out of broker) - when we query for "/index.html", the DD4T XML is returned as expected.

But when we query for "/resource.resx" or "/web.sitemap" - nothing is returned. Both pages are definitely in the broker (I can see both in PAGE and PAGE_CONTENT tables).

Through our debug code, I can even see the initial Query successfully find the TCMs for both pages, (meaning both where successfully found in the PAGE table by their URL). The problem seems to be with the PageContentAssembler.GetContent(string TCM) which is supposed to return rendered content.

Event though its given a correct TCM, it returns an empty string for both those pages - its as though it doesn't like the RESX or SITEMAP XML structure?

Anyone seen this before - does PageContentAssembler.GetContent do some post processing after its retrieved content?

Cheers
