order of precedence for component rendering

First of all does anyone know if there is an order of precedence for the way the components in a page render? Is it just top down? And is there a way to control this?

Any help would be appreciated

I believe this has been posted about in the past and I believe the answer was essentially: There is no way to determine the order of component rendering and any attempt to do so, which might work in the short-term is purely coincidental and could change without notice at any time.

That is correct and that's the reason there is no inter component communication on the same page.

From a "supported" view, the order is non-deterministic and may change across TS versions. In practice, due to the way page parsing works, it's actually the order in which the components appear in the page XML, which more or less equate to the order in which they were added to the page.

I'm providing this information to demystify how the product works, but using the above as an assumption in production code would be a big mistake.
