Re: using html:option tag
The html:select tag has an attribute value. http://struts.apache.org/userGuide/struts-html.html#select The value to compare with for marking an option selected. [RT Expr] HTH, Glenn [EMAIL PROTECTED] 27/09/2005 12:08 PM Please respond to Struts Users Mailing List user@struts.apache.org To user@struts.apache.org cc Subject using html:option tag Hi All, I am using the html option tag embedded within the html select tag to select a value from a drop down list as follows: html:select property=title html:option value=MrMr/html:option html:option value=MrsMrs/html:option /html:select This works fine and I can save the correct value to the database. The question I have is how do I display the same option tag when updating the user and the details are returned from a database. So in plain English after the user has saved the client to the db he then wants to update the record. A search is done but how do I display on the JSP page the selected option with the option of seleting something else from the drop down list. Thanks in advance
Re: Forwarding to the previous page
You can always get from where the request is coming from by getting the
Referer from the Request.
String referer = request.getHeader(REFERER);
I'm not sure that this is want you want. You must beware that the referrer
can be blank when typing in the URL in the browser, plus the consequences
of the ActionForm.validate() and errors.
HTH,
Glenn

Re: Forwarding to the previous page
2005/9/7, Duane Rosengartner [EMAIL PROTECTED]:
This works very well for me.
a class=button href=javascript:history.back()Back/a
aehm,probabily I didn't explain well my problem: I don't have to get
back to the previous page from the actual. Look at this code:
public class DisplayAboutAction extends Action
{
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse)
{
// do stuff.
ActionForward af = new ActionForward();
af.setPath(previousPagePath);
return af;
}
}
I need to get a value for 'previousPagePath'.
I'm trying something like :
bean:page id=reqq property=request /
html:link action=next.do paramId=old_page paramName=reqq
paramProperty=servletPath
but I'm using Tiles, so what I have as 'old_page' parameter is not the
action 'previous.do' but '/jsplayout.jsp' instead
thanks,

Re: Select Options Question
You can also build a javascript array of the descriptions. When the user selects the option from the list, execute a javascript function that will do a lookup for the description in the array and set a hidden form field with the description found in the array. It may happen that the character you use to delimit the key and value will end up in the value and then the fun starts !

Not the entire list. The problem is that when you submit the form, you only submit the value in the form object and loose the label. I need to pass the label as well so that I do not have to requery for it. The way that i have it currently is that the value contains a comma delemited string containing both the label and key (overkill on the bandwidth I know). In my action class, I do a string.split on the comma and pass the first value to my DAO processor and the Second value I put in my form for display. It is the only way I could think of without iterating through the options or storing the initial results which populate the option list. Frank W. Zammetti [EMAIL PROTECTED] Frank W.

If you just need the grou pname, could you simply put the group name in session? May or may not work depending on the flow of your app, but it would be a nice, simple solution if it'll work... just remember to clear it out at an appropriate time. The other option that comes to mind immediately is indeed to use Javascript... seems like all you'd need is a form with two hidden fields, groupName and value... onChange of the select, populate those two fields and submit() the form. You'd then have both pieces of information to render your detail page. Or maybe I don't understand the problem?

Requery the Database for the output page to retrieve the name given I have the key. This would work, but seems like a lot of overhead to go to the database each time. 2. Create a delimited value (ie option value=jk12341, Group 1Group 1/option) and use the String Split to get the value and label. (I am leaning toward this) 3. use javascript to update the field each time the select changes. The problem with this is that the select box can be very large based on the users selections on previous entries. 4.

Re: logout problem
I have used the meta http-equiv=Refresh content=300; URL=../action/Logout.do/ tag in an application that is very information sensitive. The idea is that the sensitive information does not stay displayed unused for nothing. This was a user requirement. BTW, you don't need an iframe. Also, you can never catch all instances where a logout will occur, such as logging off the machine... or just pressing the power button. - Glenn Leon Rosenberg [EMAIL PROTECTED] 31/08/2005 08:17 AM Please respond to Struts Users Mailing List user@struts.apache.org To Struts Users Mailing List user@struts.apache.org cc Subject Re: logout problem On Wed, 2005-08-31 at 12:46 +0100, Adam Hardy wrote: Emmanouil Batsis on 31/08/05 12:37, wrote: Sławek Tuleja wrote: question: but how to evoke Logoff action when user closes browser?

If you're mad keen on the idea and wish to avoid javascript, put an invisible iframe in the page with a meta http-equiv=Refresh content=15; URL=../action/redirect.html/ in the header, so that the client's browser continually polls the server, and set a listener to do something when it stops.

Sorry, but I've been reading archives all morning.
Using Struts 1.2.7
Setting up a system to catch all errors/messages on a page.
Getting the errors from my ActionForm:
ActionErrors errors = new ActionErrors();
errors.add(system_name,new
ActionError(errors.required,ar.getMessage(com.draegoonZ.social.label.system_name)));
return(errors);
Getting the ???bad_key??? from my ActionForm:
ActionMessages errors = new ActionMessages();
errors.add(system_name,new
ActionMessage(ar.getMessage(com.draegoonZ.social.password.lookup.no_user_name)));
saveMessages(request,errors);
return(mapping.getInputForward());
Results in: ???en_US.That username doesn't exist in our system. Please try
again.???
Now I don't know what key it is telling me is missing,
when it is displaying the value from my messages resource.
I thought the problem was with using the property (system_name)
instead of ActionMessages.GLOBAL_MESSAGE, but that gave the
same results.
Also, I want to use the property name, so I can display next to the
html:
input tag.
A related question I have is:
I read somewhere (this morning) that once html:message is read/accessed
that
it is removed/deleted.
Is this true?
How then could one list all the errors/messages at the top of a page,
and then check for them to display next to the html: input tag?
My jsp reads:
%-- check for errors --%
logic:messagesPresent
html:messages id=message_id header=errors.header
footer=errors.footer
lic:out value=${message_id} //li
/html:messages
/logic:messagesPresent
%-- If not errors present... --%
logic:messagesNotPresent
%-- check for messages (Globals.MESSAGE_KEY) --%
logic:messagesPresent message=true
html:messages id=message_id message=true
header=errors.header footer=errors.footer
lic:out value=${message_id} //li
/html:messages
/logic:messagesPresent
/logic:messagesNotPresent
