Sorry to disturb again. This issue is because default the s:hidden tag will use xhtml as theme, but actually in the distribution, there is no template/xhtml/hidden.ftl. It always get from template/simple/hidden.ftl. But the cache does not know it. Then this template is recompiled again and again.
Will report it to JIRA. A bad news for me, just know my target .net project response time is around 0.3 second. Any suggestion to improve the speed? If I use apache work with tomcat or any web server, can I get faster speed? Regards, Zheng Shuai On 2/27/07, Shuai Zheng <[EMAIL PROTECTED]> wrote:
One more thing, this only happens on template/xhtml/hidden.ftl. Should I report this as a bug?
