这个问题也郁闷了我很久,有时候session就莫名其妙的丢失了,跟踪了一下程序,发现session id突然改变了。百思不得其解,最后找了很多资料,都没有查出原因。
后来偶然看到一个关于cookie的文章,说:
MS IE+SERVICE PACK 1不能正确处理带域名和路径的Cookie,Netscape Communicator 4.05和MS IE 3.0不能正确处理不带路径和时间的Cookie。至于MS IE 5 好象不能处理带域名、路径和时间的Cookie。
一个浏览器能创建的Cookie数量最多为30个,并且每个不能超过4KB,每个WEB站点能设置的Cookie总数不能超过20个。
我突然想到,会不会是设置cookie的问题呢,因为每次操作,都用cookie作了记录,那么很容易就超过20个的,而session id也是作为一个cookie保存的,如果超过20个,那个前面的就被覆盖掉了,也就是session id被覆盖了,这样的话,session id会重新创建,原来的session就丢失了。
索性去掉了cookie,果然,session不会丢失了。所以你可以找到WebFXTreeConfig.jsc
把WebFXTreeConfig.usePersistence=true
改成false就可以了, 就不会每次去记录cookie了。
还有xtree还有一点问题,lz用久就会发现了,是节点焦点丢失时CSS还在的问题
