Any ideas? > Armin's notes on template thread-safety reminded me of this little problem. If I'm reading his notes correctly, multiple threads re-using the same parsed template object could cause this problem. But, he also notes that by default templates are parsed and evaluated for each request, so the app would have to do something to cause the same parsed template to be used for multiple requests...and from a quick look I can't see that Admin does anything like that? Does anyone have an opinion on whether it would be better to just put the existing fix in as-is, or leave this open for a bit to try to understand why it is happening?
