[OT] Re: struts2: how to read the 'potenrial list' from a database
No CC. Just list. I don't need two copies of all list traffic.

Re: [OT] Re: struts2: how to read the 'potenrial list' from a
database
Posted by xianwinwin <xi...@gmail.com>.
OK...I'm getting there! I got the idea: loadOnTextChange.
so I ended up with this JSP:
<s:url id="json" value="/groupManagement_potentialList.do" />
<s:autocompleter href="%{json}" loadOnTextChange="true"
loadMinimumCount="1" showDownArrow="true" name="userKeys" theme="ajax"
autoComplete="true"/>
BUT where is the list?!?!?!
I can invoke a method, but how does the statement above knows which list to
use?!
And what should the potentialList method return?
THANKS for any pointers!
