I'm guessing that your form bean has request scope. In this case, a new bean
will be created by Struts on the next request. That bean won't have your
list of network types, which would explain what you are seeing.
You could try putting your form bean in session scope instead. This means
that it will still be around, with the network types intact, the next time a
request comes in. To do this, add 'scope="session"' to the relevant action
mapping in your struts-config.xml file.
You should also make sure that the form bean's reset() method doesn't clear
out the network types.
Hope this helps.
