Back button problems

[Jonathan Eric Miller]

I'm guessing that this a known issue. I just switched from the JSF RI to 
MyFaces and I pretty much have everything work alright. However, I found 
that if I use the Web browser back button to go back a page and then click a 
button, it doesn't work correctly. I redisplays the same page. Then, if you 
click the button again it does what it's supposed to. Has anyone else ran 
into this problem?
