Sample code does not work

What steps will reproduce the problem?
1. create new project using "flot-android-chart - Revision 42: 
/trunk/flot-android-project" 
(http://flot-android-chart.googlecode.com/svn/trunk/flot-android-project/)
2. run app and choose "Tab Host"
3. click bar -> Basic Example -> press Back button
4. Line Tab show nothing

What is the expected output? What do you see instead?
it should go back to previous activity (tab activity) immediately and the chart 
should be still in Line Tab.

What version of the product are you using? On what operating system?

1.0, and new source from trunk

Please provide any additional information below.

I have a flot chart in a tab in my app. I can get back to this chart ONLY if I 
use intent to jump to another activity from this tab. Go to other activities 
from other tabs will make the Back process very slow and  make the chart 
disapear. No error information in catlog.

Thank you.
