Hello,
One possible solution:
Put the ArrayList in application context and put a check in doStartTag()'s beginning
to determine whether the list of states can be found in application context.
Instead of:
pageContext.setAttribute("selectStates", states);
Put it like this:
pageContext.setAttribute("selectStates", states, PageContext.APPLICATION_SCOPE);
And in the beginning of doStartTag():
Object o = pageContext.getAttribute("selectStates", PageContext.APPLICATION_SCOPE);
if (o == null) { ...do what your current code does...
}
else { ...do nothing... }
But why do this in a tag at all? If your list of states never changes, you might as
well initialize it in an init() method somewhere.

Subject: Need Help Fast
This is not really a struts question but I am using struts a maybe someone
can help. I system has allot of state dropdown's so I I made a tag for the
programmers to insert into the JSP pages.
The Tag builds a ArrayList with the states in it and then saves the states
as a attribute in the pageContext. But I don't know if this is the best way
to do it. Is it anyway to tell this code only to run one time and then stay
in member?
Below is my sample code: Please help me out
public int doStartTag() throws JspException {
java.util.ArrayList states = new java.util.ArrayList();
states.add(new com.ubspw.cdd.common.LabelValueBean("-Select
One-", ""));
