'required' is undefined when using struts javascript validation
Hi,
I'm a newbie at using strus and have been trying to get client-side validation
to work using Struts, but I 'm receiving a javascript error while trying to use
the
'required ' validation rule. The error in IE and FireFox both say:
Error: 'required ' is undefined
When I look at the generated javascript, it seems the object 'required' is not
defined in the following generated function. Can anyone give me some guidance
how to resolve this? I'd really appreciate it. Hope to hear from you soon.
function validateRequired(form) {
var isValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oRequired = new required();
for (x in oRequired) {
var field = form[oRequired[x][0]];
...
Thanks in advance,
-Paul

Re: How to Debug easier
Wendy turned me on to JSwat... as someone who historically hasn't found much use for a debugger, I have to say it has been a joy to use. And it is a fairly light app, certainly far lighter than a full IDE would be. If you develop under Tomcat, it attaches very easily too. If anyone feels the need to use a debugger, I very much recommend JSwat.

RE: Displaying errors for all except one key
Hi again, everybody!
I promised I'd report back with results. I think the tag is working
quite well so far, and it turned out to be pretty simple to extend the
html:messages custom tag. I got the source code and overrode the
doStartTag() method. I left all the original source in place but added
this:
//Were any properties to be excluded?
Configuration config = Configuration.getConfiguration();
String excludedProperties =
config.getValue("excludedProperties");
ArrayList excludedList = new ArrayList();
if(excludedProperties!=null &&
excludedProperties.length()>0){
String[] excludedArray =
excludedProperties.split(",");
for(int i=0;i0){
ActionMessages tempMessages=new ActionMessages();
Iterator tempIt = messages.get();
while(tempIt.hasNext()){
ActionMessage
tempMessage=(ActionMessage)tempIt.next();
if(!excludedList.contains(tempMessage.getKey())){
tempMessages.add(tempMessage.getKey(),tempMessage);
}
}
messages=tempMessages;
}
That was it. The JSP code is actually simpler than it was before:
<%-- Display Error Messages if the showErrors parameter is true --%>
Etc.
So I'm just displaying everything but I'm using my custom tag instead of
the default one from html:messages, and that custom tag does the
exclusions I need.
I do have a problem I should solve: in the case where the only error in
errors is one I need to exclude, it does get excluded but I also get the
empty which displays a big red box on my page. Fortunately, that
happens very rarely. I guess I could extend messagesPresent as well to
take care of that.
Thanks again for the help. I really appreciate it.

Yes, I wouldn't be able to get away with the empty tag -- it would
create a great big red box on my page which wouldn't be acceptable.
I'm working on extending html:messages, and it's working quite well (and
surprisingly easily) so far. I'll do some more testing tomorrow and if
all goes well, I'll post what I've done.
Again, thank you very much for your help.

If you have the something like this in your jsp, even if you have only
one error that you would want to exculde you will be left with only a
If you don't like to display the empty div when there are no errors, you
would have to do some processing of the "properties" to see if you have
atleast one other property other than the one that you want to exclude
then only show the div and the errors. But anyway, is showing an empty
div that big of an issue?

There is no super method in HtmlMessages tag that can take the
collection of errors and iterate. You would have to override the
doStartTag of the HtmlMessages tag and create the iterator excluding the
errors that you don't want to see.

Re: question about Struts html tags and Javascript getElementById
According to the docs,
http://struts.apache.org/userGuide/struts-html.html#file, the html:file
tag will render and id tag with the attribute styleId. Also, when I use
getElementById I just call it on the document. So what I think you are
trying to do is so:
styleId="uploadedFiles1" accept="image/jpg, image/jpeg">
styleId="uploadedFiles2" accept="image/jpg, image/jpeg">
styleId="uploadedFiles3" accept="image/jpg, image/jpeg">
styleId="uploadedFiles4" accept="image/jpg, image/jpeg">
In javascript you should be able to get a reference to those nodes by
calling document.getElementById("uploadedFiles1"), for example.
That being said, what I showed you is not the way I would do it. Also,
your property attributes look funny to me. I would do this.
accept="image/jpg, image/jpeg">
accept="image/jpg, image/jpeg">
accept="image/jpg, image/jpeg">
accept="image/jpg, image/jpeg">
(I think you'll want surrounding the html:files, I omitted
them for space).
Even without the id attribute you can still easily get a reference to
these nodes in javascript
You could call a javascript function when the form submits, i.e.
. In the javascript
you could get the reference to the html:file nodes like so:
function verify(form){
/* this will return an array of the html:file nodes with
property="uploadedFiles" */
var fileInputs = form['uploadedFiles'];
}
Some of my syntax could be wrong, but the jist of it should be correct.

Re: Action[/UpdateDeleteColecao] missing resource 'button.delete' in key method map
Seems to me that you do not really understand what
LookupDispatchAction is for and how does it work. Do you have property
file that maps button caption to "button.add" property name? Well,
even if you do, you do not have to use LookupDispatchAction, because
you use a link.
Use standard DispathAction instead. Or use something else, like
SelectAction, which works uniformly with pushbuttons, links and
imagebuttons:

I wouldn't suggest using at all in this scenario. Put
the getList() method on your backing bean that contains the event
handlers for that page, which would be registered as a managed bean
(in request scope). Then, you can use value binding expressions to
connect your components to the list values.
The only thing I would do differently from David's example is put the
populateList() call in prerender(), instead of in the getter method.

Re: Action[/UpdateDeleteColecao] missing resource 'button.delete' in key method map
Well, if it worked like the html:button, it would send the method with the
value from the bean. But it obviously doesn't. So, I put this js function
to
be called onclick:
function dispatchIt()
{
document.addColecaoForm.action="/AugeProducao/UpdateDeleteColecao.do?method=
button.add";
document.addColecaoForm.submit();
}
And that's causing the error. So, if the property=method doesn't work, and
passing it literally doesn't work... that means I cannot use links to
submit
the form? Or am I doing it totally wrong?
You're on the right track... but I admit to just hardcoding the text value
for the
button. :)
Change it to method=Add (or whatever the value is from
ApplicationResources.properties) and it should start working. From there,
you can figure out how to retrieve the value for the right locale. Without
actually trying it, I think possibly and (JSTL) and
then use an expression inside the script.

This would work (although you'd probably want to do some sort of
in-request caching so you don't call populateList() more than once),
but I tend to shy away from making getter and setter methods for
properties have side effects like this. It's much clearer (well, to
me anyway :-) when pulling data from the model is explictly called out
in its own methods.

this technique works not only for the welcome page, but for *any* page
to which you navigate (in Struts Classic terms, this is the kind of
thing that you use a Controller for in Tiles). :-)
If you wanted to do it the hard way, you could set things up to
register a phase listener, and call your list setup logic in a "before
render response" event handler ... but that's the part Shale takes
care of for you.
Ok, I'll try this with Shale, although I'm really surprised the
framework (JSF) doesn't take care of this for you by default? In struts
it's so simple, I simply forward to an Action that populates my
employees. I'm still trying to get a handle on all of this and it seems
like things are done so many different ways that's it's quite confusing.
Complicating matters of course is every example I'm finding seems to
deal with more advanced features that I don't care about at this time -
I don't want the bells and whistles yet, just the meat:).
Making matter worse is that I do want to use Tiles. Bascially what I
want is something very simple
User goes to
/webapp/index.jsp (or just /webapp - welcome file will be index.jsp)
This ends up bringing the user to a page...
/webapp/employees.jsp that looks like
--
header (a tile)
-
|
|
menu |
(tile)| { display a list of employees }
| (body tile)
|
What is the standard way of accomplishing this in JSF? I'm looking at
Geary's example in Core JSF with Tiles but that doesn't seem to help
much in this case and I've been looking over the MyFaces tiles example.
The former deals with Tiles in a more advanced example (nothing in the
faces config) and the later deals with tiles where no business logic in
any classes needs to take place.
I guess I'll try all this first without using tiles.

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
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 input tag?
My jsp reads:
<%-- check for errors --%>
<%-- If not errors present... --%>
<%-- check for messages (Globals.MESSAGE_KEY) --%>
Thanx in advance.

Thanks for the help
If I understand you correctly, you have something like: index.jsp does a
to foo.faces (a jsf page).
If so, then I think the backing bean is invoked in foo.faces when the
is referenced. So, the backing store bean is already
created *before* the foo.faces is rendered to the browser. At least,
that's the way it is working for me...
As a quick test, you could create a test foo.faces that contains:
The bean has this:
and have the bean something simple like:
public class FooBean {
priviate String string = "foo";
public FooBean() {
super();
}
public String getString() {
return string;
}
public void setString(String string) {
this.string = string;
}

Re: Action[/UpdateDeleteColecao] missing resource 'button.delete' in key method map
Well, I should be embarrassed by now. Actually, you're 100% correct:
something is sending literally 'button.delete' as the value of method param,
instead of the value from the .properties file. And this something would be
me.
It happens that I am not using html:submit buttons to call the dispatch
action. Instead of it, I'm trying to use links, like this:
Well, if it worked like the html:button, it would send the method with the
value from the bean. But it obviously doesn't. So, I put this js function to

function dispatchIt()
{
document.addColecaoForm.action="/AugeProducao/UpdateDeleteColecao.do?method=

document.addColecaoForm.submit();
}
And that's causing the error. So, if the property=method doesn't work, and
passing it literally doesn't work... that means I cannot use links to submit
the form? Or am I doing it totally wrong?
Sorry, thanks.

Re: displaying JSP errors on screen
Hi, are you using tiles as well? I experienced the same problem some time ago, but only in tile-based .jsp, not in 'pure' jsp. I could not pinpoint the exact time when this started since I wasn't working on the display part at that time but one of the bigger changes I did shortly before I noticed this was the switch from 1.1 to 1.2.4. After some time I got used to looking in the console for problems so eventually I just stopped looking for the reason. Sorry that I can offer no help, but it might console you to know that others have the same problem.

Re: displaying JSP errors on screen
Hi Frank, Thanks for your time. In fact the 'errors' I expect are mostly tags where the expected object cannot be found in any of the scopes. I used to get those "javax.servlet.jsp.JspException: Cannot find bean xyz in any scope" in my browser but since I switched to 1.2.x they are all silent and I only see them in my Eclipse console. Which is quite ok, but this is itching for some time now. Could be I'm barking up the wrong tree here and forgot to define a valve/logger/whatever in my context of overlooked some 'tinkering' at another config file which accidentally slipped in all my new projects... regards, Martijn Frank W.

Validator's indexedListProperty
Hi, I've been playing with the indexedListProperty to validate what a user has selected in my forms. The problem I am having is that when an error message gets returned, It does not get associated with the form element ( in my case). I think the problem is that the message comes back with a key of test[x] where x is the index of the error. If I just print out my error messages like this I can see the error message, but doesn't show anything. It seems like the tag should have an indexedListProperty parameter as well so I can display my error messages correctly. What am i missing?

Hi all, I have a where I am iterating over a list of objects. Each object has a property label, which is being displayed as a textbox. Now, I have a hidden field hdnField, for each row of object.

It works fine for static tags like or in , eg. ');" /> Any way to solve the problem? A work-around is to update the hidden field in each row just before submitting the form.

Re: [Friday] [somewhat-ajax-related] XMLHttpRequest scoping problems
I haven't actually tried having multiple simultaneous requests with

req = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
req = new ActiveXObject("Microsoft.XMLHTTP");

req.onreadystatechange = function() { processResponse(req); }
req.open("GET",url,true)
req.send();

Re: LookupDispatchAction-problem getting started
From: "Tiller, Volker" <[EMAIL PROTECTED]> I can't get started with the example about using LookupDispatchAction of Ted Husted, Tip #3 (http://husted.com/struts/tips/index.html). What is my error or can I get some working code ? The 'method' parameter should be set to the _value_ from ApplicationResources.properties (not the key). I'm not sure how to encode the spaces to do this manually, maybe method=add+it+all or method=add%20it%20all. Or maybe the spaces will just work. (It's early...) Here's what happens: - the framework sees "add it all" as the value of the 'method' parameter - it figures out that 'add it all' came from the 'button.add' property - looks up 'button.add' in the keyMethodMap and finds 'add' - calls the 'add' method in your Action (Naming the parameter something other than 'method' may make things clearer-- maybe 'choice'.)

Re: dynamic forward path?
thanks for this idea; I implemented it the way you suggested - with this solution everything is still configurable through the struts-config file as you are stating below ... thanks a lot, karin. Laurie Harper wrote: Karin Schellner wrote: I am new to Struts and would appreciate your ideas for a solution to the following problem: In my webapplication I have a login-form with a submit and cancel button. When the user clicks the cancel-button I would like to return him to the page he previously visited (before calling the page with the login-form). Using a forward in the action-mapping would redirect the user always to the same page (e.g. welcome.do), therefore I was thinking of storing the last visited page in the session and use it for a redirect, but then I would bypass the struts-config ... what do you think? Is there a possibility to achieve this in Struts? The second option is the one you want. There's no way you can statically define a forward in struts-config that points to 'the page the user was on before this one'. What you could do, though, is create a ReturnToPreviousPage action which redirects to the URL you stored in the session and have an action forward in struts-config pointing to that action. You still have to keep track of where that action should redirect to yourself (though the session or whatever). The advantage is that your struts-config is still declaratively declaring the behaviour -- and you can then change the behaviour (e.g. to always forward to the application home page instead of the previous page) by modifying the config. You also get the option to re-use the ReturnToPreviousPage action anywhere else you need the same behaviour.

Re: [SHALE] Simple "getting started"-type question
Thanks to both of you, that definitely helped. I'm going to go read a tutorial or two now... I actually have in the past, and also saw some code-intensive demos at two user group meetings, so I thought I had at least the JSF basics in my brain already... as it turns out, that might not be quite true :) And in any case, this is the first attempt I've made at actually getting hands-on. Frank David G. Friedman wrote: Frank, I hate to try to answer a question after Craig, but from my JSF newbie point of view, I didn't get an answer I'd want from his letter. So, here's my try to help answer your questions. Just keep in mind I'm re-reading (2nd time around) a JSF book so I'm no authority. MyFaces, JSF actually, doesn't care about action mappings, like Struts does. When a url comes in which maps to JSF (or Myfaces) such as a *.faces URL, JSF looks for a file matching that url but ending in .jsp, not .faces. That's how /usecases.faces maps automatically to /usecases.jsp. Why does it do that? The mapping of *.faces allows MyFaces/JSF to do the JSF tricks listed in the jsp file which could include bean auto-population, page redirects, validations, navigations, callback functions, templates, etc. A tree is made of the JSF components from that page so further visits to that page don't require a rull re-parse of the page. In my opinion, JSF navigation seems to care more about the direction of where to navigate next than how to come into a page. You'll see loads of those 'where to next' ideas in the faces-config.xml file as 'navigation-rule' sections. A few useful tidbits of knowledge: 1. Everything JSF starts inside the f:view tags. 2. The *.faces don't have to map to *.jsp extension files. A servlet container configuration parameter allows you to specify the default extension to use so you could use something other than *.jsp for your actual files. You can also change your incoming *.faces URL mapping to *.html to hide the fact that you're using JavaServer Faces. 3. JSF can be sufficiently complicated to 'look at' if you haven't read a JSF tutorial or book so jumping into Shale could be even more confusing. Shale confuses me some and I've read a JSF book once (I'm on read #2 as I mentioned). 4. There are plenty of JSF tutorials at www.jsftutorials.net. (I've read a few of them, I'm reading about Facelets now - kind of a 'Shale Clay' alternative.) This includes a section on their front page entitled: Golden Collection for JSF Newbies. 5. navigation-rules got a little confusing for me when looking at JSF with Tiles, especially with Shale's Tiles mapper. I think it (Shale's Tile mapper) looks for a tile with a name very similar to the jsp name and if one isn't found, it skips tiles and looks for a regular jsp instead. Craig could comment on that if I'm wrong or off slightly but I think I just read about that last week. 6. In case you need it, myfaces is at http://myfaces.apache.org. Tomahawk if the name of their set of custom add-on components, which you don't need if you are trying out JSF. You can just use the MyFaces (non-Tomahawk stuff) implementation of JavaServer Faces.

My question is, where is that mapping defined? It's obviously winding up at usecases.jsp, and I can see that .faces is mapped to FacesServlet in web.xml, so it's straight-forward to an extent, but I'm not seeing in the config files were something akin to a Struts path to /usecases is defined. I assumed it would be in faces-config.xml, but unless I'm really missing something, it's not (by the way, I *DO* assume I'm missing something there!). Thanks! -- Frank W.
