Many many questions have been posted on this list that are clearly explained in the documentation. The documentation isn't perfect, and can be confusing at times, but some due diligence should be expected.

Re: Problem populating form bean with multiple parameters of same name
Renaud,
I appreciate your response, but unfortunately when the JSP is regenerated and
displayed, Struts places the toString() value of the String array into the
tags, such as:
[Ljava.lang.String;@262bf4
I have also tried a twist on this strategy, with:
private String propertyName[];
private int propertyNameIndex;
public void setPropertyName(String[] propertyName) {
this.propertyName = propertyName;
propertyNameIndex = 0;
}
public String getPropertyName() { // send default value if index out of
range
return ((propertyNameIndex < propertyName.length) ?
propertyName[propertyNameIndex++] : "");
}
I was hoping that this strategy would allow the JSP to populate each field with successive calls to getPropertyName() but this then results in:
javax.servlet.jsp.JspException: Exception thrown by getter for property fileName
of bean org.apache.struts.taglib.html.BEAN
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:513)
If anybody has any other ideas on how Struts can read multiple text input
fields, all with the same name (akin to ServletRequest.getParameterValues(String
s) ), and properly populate those same fields when the JSP is displayed again, I
would greatly appreciate your thoughts!
TIA, Steve

Problem populating form bean with multiple parameters of same name
Does anybody know how Struts be made to populate an ActionForm bean with
a variable number of text input fields that all have the same name?
For instance, there may be 0, 1, 5, 10, or any other number of
tags in an .
I want Struts to populate the ActionForm bean with all of the
"propertyName" values, either one at a time via multiple calls to the
ActionForm's setPropertyName(String propertyName) method, or all at once
in an array (or other data structure) much like would be accomplished
with the ServletRequest.getParameterValues("propertyName") method.
I have tried to accomplish this any number of ways but have been
unsuccessful and haven't seen anything in the documentation explaining
how this should be done.
TIA, Steve

Re: multi form pages
What you are asking is really an HTML question. I don't believe you will have any problem with multiple forms on a single page. However, I do believe that only the parameters of the submitted form will be sent to the server. I've never tried this and am willing to be corrected by anyone who knows for certain!

RE: Navigation history
If your current pageN values map directly to JSPs, and you want the navigation through those particular JSPs to be contained in the bread crumb stack, then I believe you would need to map the pageN values to Actions that would handle the appropriate bread crumb logic.

Re: Navigation history
One implementation has been to subclass the Action object with another object (named something like OurGeneralAction). All of your other Action objects, such as LogonAction, LogoffAction, DoSomethingAction then subclass OurGeneralAction. Just prior to returning an ActionForward from your specific Actions (Logon, Logoff, etc.) you call a doBreadCrumb(String actionFwdName, HttpSession session) method that is contained in OurGeneralAction. doBreadCrumb() looks in the session object for another class (perhaps called BreadCrumbs) that push or pop the actionFwdName from a stack. That stack can then be used from a JSP using logic:iterate and bean:write to display the list of "bread crumbs". There are a variety of details and complexities that are left out of this description, such as how you determine whether to push to, or pop from the stack, the exact text to display for each bread crumb, etc. However, the general idea is represented.

Re: [ANNOUNCE] Struts Console
I concur that this is off to a nice start and should be useful to many people.
If you want to tailor the EOL for the particular platform (you may already know this)
you can append System.getProperties().getProperty("line.separator") to the end of each
line instead of hardcoding '\n' or "\r\n".
