Re: RE: Populating form in the action
The form passed in is a null because that Action is
called the first time I type in the URL (.do), not
after a form has been submited.
In other words, I would like to pre-populate the
form before displaying it.
If you have associated the action with a form in your struts-config.xml, then any time
your perform() method is executed, there should be a form instance present. I use this
on my site. I do a GET on the action to, for example, edit my account record. I fetch
the user record, prepopulate the form, and then forward to the jsp. Here's a code
snippet:
public void perform(..., ActionForm form, ...)
{
UserForm userForm = (UserForm) form;
if (request.getMethod().equalsIgnoreCase(get))
{
userForm.setName(...)
// ...
}
}

Re: RE: Populating form in the action
For instance, I create a ActionForm in the perform method of the Action class, and then forward the control to a jsp page. How does the JSP page know that the form that it gets is the form that just get populated in the Action before? Don't create an instance of the form, use the one that is passed in to your perform(...) method. You will need to cast it, of course.

Re: Icons next to form elements with validation errors
logic:messagesPresent property=username // insert image here /logic:messagesPresent html:text property=username size=20 maxlength=100/ What about using html:errors next to the field in question and having the error message contain an img tag to the icon? In your action, set the error message: ActionError err = new ActionError(error.search.crit); errors.add(searchCrit, err); Then in your jsp: html:text.../html:errors property=searchCrit/ And in your AppRsrs.properties: error.search.crit = img src=/images/nocrit.gif/ This works for me.

Re: Passing information to the jsp
If you want to pass data to a jsp, where the information will not be in an HTML form, do I need to pass it through the ActionForm that is in the mapping, or should I just put a bean in the request and use it on the jsp? If you need to pass info that won't be in the form, then I would think it perfectly acceptable to send it in the request using setAttribute(). There's no reason to clutter up your form code with getters/setters for data that your actions don't need.

Re: Help with perform method
What I would like to do is that if there is some type
of error in this
method, I want to be able to do a
mapping.findForward(failure) and at the
same time be able to include some type of error
message to the user in the
failure page. My failure page is probably the same
form the user filled out,
but the second time around I would like to display
the error message.
This is what ActionError, ActionErrors and html:errors/ is for.
perform(...)
{
// ... processing ...
ActionErrors errors = new ActionErrors();
ActionError err = new ActionError(error.username.taken);
errors.add(ActionErrors.GLOBAL_ERROR, err);
saveErrors(request, response);
return new ActionForward(mapping.getInput());
}
Then in the jsp page, you can simply add:
html:errors/
somewhere conspicuous to get the errors to display.

Re: check for null collection
If the collection is truly null, then logic:present will be false so you won't get into the tag body. To see if the collection is just an empty collection: Inside your logic:present you can use a combo of tags from the bean and logic taglibs: bean:size id=mySize name=myArray/ logic:equal name=mySize value=0 No records. /logic:equal logic:notEqual name=mySize value=0 bean:write name=mySize/ record(s) /logic:notEqual And you don't have to do the bean:define since most of the tags will be able to find the collection in whichever scope it is in. In my sample program that I wrote to test this information, I created a List and shoved it into the request. I never mentioned which scope it is in, though you can specify.

Re: relatively complicated iterate problem.
My problem is. I don't want to use Roll class, since it only contains a string. I have just created this Roll class, since I couln't find any way to make it run with struts. What do you think? is there any other way to do same thing? If you don't specify the property attribute, the tag will do a string comparison. I've got code like this in a working project: logic:equal name=resultsSize value=0 that works with a variable created by bean:size earlier in the page. -- Sent via jApache.org -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: JSP page without form bean ?
What exactly are you trying to do? I have several actions that have no forms that work fine. I do GETs to them, do some processing, and then forward to a jsp. Sent via jApache.org -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: RE: Dynamic anchor
This might be a wee bit cleaner: %@ taglib uri=struts-bean.tld prefix=bean % %@ taglib uri=struts-html.tld prefix=html % bean:define id=foo value=xxx/ html:link page=/index.jsp anchor=%= foo %Foo/html:link This produces this link: http://localhost/foo/index.jsp#xxx (the page was deployed in a webapp called 'foo') I tried putting a bean:write in the anchor attribute, but it goes through unadulterated, which is not what we want. I really wish some of these tags could nest more easily. Joey -- Sent via jApache.org -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Present/NotPresent Blows Up With SilverStream 3.7
I'm deploying some struts-apps on SilverStream 3.7 (don't ask...) but the logic:present and logic:notPresent tags die if the object-that-I-want-to-check-for is not present.

Re: Present/NotPresent Blows Up With SilverStream 3.7
I just did some more testing (I always seem to gain insight after I post...) and I discovered that it is the SECOND occurrence of a present/notPresent on a page that dies. If I have a present that fails, and then have another present/notPresent, on the same bean or a different bean, it will die whether or not the bean is present of not. I can verify this by moving the dying present/notPresent before the successful one, and then the failing one works and the successful one dies. It would appear from the error message and my cursory investigation of the Struts source that when an attempt is made to find a bean, an exception is being caught and stored in the org.apache.struts.action.EXCEPTION, and subsequent attempts to replace that value with another caught exception are what is hosing it down. So, has anyone else seen/verified this situation and what can/should I do about it?
