Re: BeanUtils.populate Error
Problem was resolved. but the reason was not exactly clear to me. What I am doing was: I was using the html:image tag of struts for replacement of html input type=image tag In this i was using html:image property=addButton value=continue srcKey=ask-question.button-submit.image altKey=ask-question.button-submit.alt border=0 / FYI -- I had this addButton declared in my Action Form. Actually I am having more then one image sumbit button in my form. when I removed the property attribute. it worked fine.. I think this was the reason... I don't know otherwise.

RE: ClassCastException coming from DynaValidatorForm.validate()- bug or a feature?
Hi, Validator has support for validating multi-page forms via the use of an optional page attribute, associated with a field element, that can be set to an integer. From the Validator portion of the user guide: All validation for any field on a page less than or equal to the current page is performed server side. All validation for any field on a page equal to the current page is generated for the client side Javascript. A multi-part form expects the page attribute to be set html:hidden property=page value=1/ Since your form already defines a page property, and a non-integer one at that, I can see how things might get screwed up.

Re: Problem in forward path in tileDefinitions.xml
You don't have to create a definition if you are simply forwarding to a JSP. If the TilesRequestProcessor is not able to find a definition matching the forward path specified it calls the standard Struts RequestProcessor which will handle it as a normal URI.

Re: error:null property value please HELP
Hi Ajay
I am doing something similar... I have a Tree class and a Node class to
represent either branches or leaves of the tree.
The Tree class has a field called treeRoot that represents the root Node.
I ha ve an action that creates the tree and puts it on the request
then in the JSP I have something like:
%-- Loop through the array list of trees to display each root node.
Note that 'myTree' was placed on the request by an Action --%
logic:present name=myTree
nested:root name=currentTree
nested:nest property=treeRoot
div class=root
jsp:include page=treenode.jsp /
/div
/nested:nest
/nested:root
/logic:present
Actually my jsp is slightly different because I can have multiple root
nodes and I also iterate through each root node to display each tree. I
have chopped those bits out to make the code more readable.
So it seems that you are trying to reference a field functions that
isn't declared in your tree class.
Hope that helps.

Re: error:null property value please HELP
hi!
'functions' is the name of the tree structure in the form class, as
class SomeForm extends ActionForm
{ private TreeStructure functions;}
this form class also includes some String attributes. The whole display
works fine, i have some text boxes for the String fields in the form, the
tree structure gets displayed with the corresponding checkboxes. the problem
arises when i select a particular checkbox and submit. thats when i get the
error i mentioned earlier.
however if i just fill the text boxes and do not select and checkbox the
form submits fine.
any clues?
thanks

Re: error:null property value please HELP
Hi Ajay,
Sorry, I didn't realise the problem had to do with checkboxes. I can offer
a clue or two perhaps but you would be best off reading the struts doco on
checkboxes.
clue 1: checkbox values are stored as Strings.
clue 2: only selec ted checkbox values are submitted, not unselected ones.
you probably knew that already, hence my suggestion to read the struts
doco.

Subject:Re: error:null property value please HELP
hi!
'functions' is the name of the tree structure in the form class, as
class SomeForm extends ActionForm
{ private TreeStructure functions;}
this form class also includes some String attributes. The whole display
works fine, i have some text boxes for the String fields in the form, the
tree structure gets displayed with the corresponding checkboxes. the
problem
arises when i select a particular checkbox and submit. thats when i get
the
error i mentioned earlier.
however if i just fill the text boxes and do not select and checkbox the
form submits fine.
any clues?
thanks
Ajay

Hi Ajay
I am doing something similar... I have a Tree class and a Node class to
represent either branches or leaves of the tree.
The Tree class has a field called treeRoot that represents the root Node.
I ha ve an action that creates the tree and puts it on the request
then in the JSP I have something like:
%-- Loop through the array list of trees to display each root
node.
Note that 'myTree' was placed on the request by an Action
--%
logic:present name=myTree
nested:root name=currentTree
nested:nest property=treeRoot
div class=root
jsp:include page=treenode.jsp
/
/div
/nested:nest
/nested:root
/logic:present
Actually my jsp is slightly different because I can have multiple root
nodes and I also iterate through each root node to display each tree. I
have chopped those bits out to make the code more readable.
So it seems that you are trying to reference a field functions that
isn't declared in your tree class.
Hope that helps.

hi!
i am getting an error when i submit a form.
briefly i have a tree stucture that gets displayed, along with checkboxes
to
select a particular node. the tree structure is of the type:
class TreeStructure{ private ArrayList children;} //the ArrayList
children
contains objects of type
//TreeStructure
the structure includes a property 'selected' of type boolean.
My ActionForm includes the tree as a property called 'functions'. i
display
them as
html:form action=/saveUserConfig
nested:nest property=functions
jsp:include page=treenode.jsp/
/nested:nest
html:submit value=Submit/
/html:form
//treenode.jsp is
nested:root
nested:checkbox property=selected value=true/
nested:write property=nodeName/br
RE: OT: Examples of HTML-based user interfaces?
Thats good. Btw: If I were you I would set the Netscape bar to version 7 (or any mozilla version above 1). Netscrap 6 is based on a pre-1 version of Mozilla, and has a couple of very nasty bugs that can make trying to do certain DHTML things an absolute nightmare. (Such as not submitting values for controls that are under hidden nodes, etc...) The other thing to keep in mind is that JavaScript widgets always seem to take far longer to implement than you think they will! - So the simpler you can keep things the better, and as with all languages using good programming techniques in JavaScript will pay off when it comes to maintenance and enhancement. Its very easy when coding JavaScript DHML stuff to just anyhow try and bang together something that runs but where the code is very ugly. Ive learnt the hard way that it quickly becomes a nightmare to maintain! (and yet I keep doing it. garrgh! (99.9% of the freely downloadable JS widgets to be found on the net on various DHTML sites are nasty like this. Its often actually easier to roll your own than to try and find a suitable widget out there and modify it for your needs (tree components being a prime example)) So even if its just a simple widget like the two box selector thinghy, sitting down to design it properly , and make it modular and reusable (for example writing a custom tag to encapsulate it in a way that seems transparent to the page designer), will pay dividends! If your not totally familiar with the subtle details of JavaScript (how objects work, prototyping, implicit type casting etc...), spending a day studying the language in detail (ie: actually making notes like you did back in college) will be a day well spent! (it will save you at least a week debugging!) hth Andrew -Original Message- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: Friday, 19 December 2003 22:36 To: Struts Users Mailing List Subject: RE: OT: Examples of HTML-based user interfaces? From: Andrew Hill [mailto:[EMAIL PROTECTED] Still, if you are in a position to limit your audience (such as with intranet apps) to just the more common modern browsers (IE5+, Mozilla) there is indeed a lot you can do with DHTML. I should have said that up front-- it is intranet and we can (and do) refuse to support browsers which won't play nicely. All I officially have to support is a reasonably recent IE Netscape. And they can't disable javascript, or they won't get very far. :) I don't go out of my way to break stuff on other browsers (and I test from home on Mozilla/Konqueror) but if it gets to be too much trouble, I don't have to mess with it.

RE: [other] error tag
Hi Noel, Thanks for that. Since that post, I have opted for constructing an ActionMessages object and populating it with ActionMessage (s). This being because I hear ActionError/s are deprecated as of Struts 1.2. I have set up the Application.properties file under WEB-INF/classes/resources containing: initialisation.error=Initialisation error - invalid UserID I catch the exception thus: ActionMessages messages = new ActionMessages(); ActionMessage errorMsg = new ActionMessage(initialisation.error); messages.add(init_message, errorMsg); saveMessages(request, messages); and forward off to the error page, but nothing is rendered. Any idea here? Perhaps something to do with the init_message string I am passing? What does that represent? appreciated G. Hi Jerald, The single-string ActionError class constructor that you are invoking interprets the parameter passed to it as a key of a message string defined in your Application.properties file (this file is usually placed under the classes/resources directory).

RE: [other] error tag PS
it just occurrred to me, perhaps it may be due to the JSP: html:errors / as ActionMessages are not soley used for error handling? If this is the case, what error tag will extract the error labels defined in my Application.properties? thanks again G - Yahoo! Messenger - Communicate instantly...Ping your friends today!
