Subject Re: Using <html:select> tag
Date Fri, 23 Sep 2011 07:16:58 GMT
Hey Anjib,

1 - Check out the tablib docco (
http://struts.apache.org/2.x/docs/select.html). For example with html:select
you could use listKey and listValue. Should be something similar for
html:options. I always use html:select though as much less code for what I
need.
2 - Have your action implement Preparable. Then in the prepare method you
load the agency names.

Hope that helps.

Carl.
