Facebook writing dialog don't show message

I write an message by facebook dialog after login. Before write, in Facebook.java, I assign message using this code( parameter.putString("message", "bla bla");) But as you can see in the picture, the message box is empty. Previously, the problem was unprecedented. No change in source. But a few days ago, the problem have occured. Follwing is FbDialog.java'开发者_如何学JAVAs log(onPageStarted method). Message is not empty. What is the matter? :)

Facebook is now ignoring the message parameter:

http://developers.facebook.com/blog/post/510/

message : This field will be ignored on July 12, 2011 The message to prefill the text field that the user will type in. To be compliant with Facebook Platform Policies, your application may only set this field if the user manually generated the content earlier in the workflow. Most applications should not set this.
