PropertySelection
Hello,
In a page that display a query form and query results together,
I want to remember the property selected by the user for the last query. I
store this value in a page property, but I cannot get the PropertySelection to
render using the previous value for the default value. It reverts to the value
of index 0.
My current solution below use LabeledPropertySelectionModel and results in
duplicate option in the pull-down.
Any help appreciated,
Alex./

Border question
Hi, I'm looking for advise, tips or idea here. I'm beginning the development of a site in Tapestry 4.0 and I don't know how to implement all my levels of menu without creating many border page.What I'm trying to do is implementing component that will render my menu. The problem I have, is that all example I saw like the library example and others just have one level of menu.Us, we got 3. Each page include all the menu and should Highlight the corresponding one when you are in the good section, in the good subsection and in the good page.All menu are genereted server side so no need for _javascript_. The final sites will have many pages, like ~50 to 75 so we don't want to duplicate all the html code of each level menu to display the good menu.For now, The only way I saw I can do this is by making a border level3 wich include a border level2 wich include a border level1. The problem with that is that I need to have a border level 3 for each item in the level2 and so one...Don't forget that each item in the menu will be secure, so a logued user will see somes items of all menus but not necessary all items.this site is a admin site and will be bind with Hibernate. I don't use Spring, structs or anything like that...I joint a picture of the design for help.If you can give me some tips, some idea or best pratice on that, It's will be very appreciate.

Re: Issues with Label Components with Tapestry 4.0
Sure, but at that point you are basically overriding the behaviour provided
by the ValidationDelegate when it does before/after field rendering (not
talking about FieldLabel).
The FieldLabel component already supports informal parameters.
I noticed in your first email you mentioned trying to do this with something
like
label jwcid=mycompid class=class1 class2 and only saw class1 output.
Try doing this instead (though I agree it sounds like a bug somehow):
label jwcid=mycompid class=ognl:'class class2' /

On May 31, 2006, at 2:51 PM, Ryan Holmes wrote:
Your problem getting the span tag where you want it is due to how
the FieldLabel component renders itself. Here's the relevant part
of FieldLabel.renderComponent():
delegate.writeLabelPrefix(field, writer, cycle);
writer.begin(label);
if (id != null)
writer.attribute(for, id);
delegate.writeLabelAttributes(writer, cycle, field);
renderInformalParameters(writer, cycle);
writer.print(displayName, getRaw());
writer.end();
delegate.writeLabelSuffix(field, writer, cycle);
You could argue that writeLabelPrefix() and writeLabelSuffix()
should both be inside the label tag (makes sense to me), but the
current code is symmetrical and not necessarily wrong. Your best
bet is probably to override the FieldLabel component with your own
version that renders the delegate prefix and/or suffix inside the
label tag. And I'm sure you won't hesitate to file a bug report if
you feel strongly about it ;)

Thanks. This works, but it also prints out duplicate class
attributes.
class=text large error class=text large
It'd be nice to have something like:
writer.appendAttribute(class, values to append);
Another question - it seems my full label and input is
getting wrapped with
font color=red
Is there anyway to get rid of that? It's problematic b/c the
closing /font isn't getting rendered until right before /form.
Fixed this by using:
public void writeLabelPrefix(IFormComponent component,
IMarkupWriter writer,
IRequestCycle cycle) {
// does nothing put prevent font color=red from getting
written
}

Hmmm, I'm guessing the answers to my questions below are no,
this isn't possible. ;-)
Here's another question - is it possible in my custom Validator
to get the existing CSS classes on a component? For example, I
currently have:
public void writeLabelAttributes(IMarkupWriter writer,
IRequestCycle cycle, IFormComponent component) {
if (isInError(component)) {
writer.attribute(class, error);
}
}
public void writeAttributes(IMarkupWriter writer,
IRequestCycle cycle,
IFormComponent component,
IValidator validator) {
if (isInError()) {
writer.attribute(class, error);
}
}
But I'd prefer to have something like this:
public void writeLabelAttributes(IMarkupWriter writer,
IRequestCycle cycle, IFormComponent component) {
if (isInError(component)) {
writer.attribute(class, error +
component.getAttribute(class));
}
}
public void writeAttributes(IMarkupWriter writer,
IRequestCycle cycle,
IFormComponent component,
IValidator validator) {
if (isInError()) {
writer.attribute(class, error +
component.getAttribute(class));
}
}
In other words, is there a method on component that allows me
to get the current CSS classes?

The first is a simple component (just a Label.jwc and

XMLHTTPRequest within tapestry
hi all,
i am trying to implement XMLHTTPRequest within my web app. now for
starters i would like to display a log file (which is constantly
updating), within my web app. how should i display its contents
without refreshing the page manually (it should display information as
the log gets filled in).
this is my code for JavaScript within the html file so far, but i dont
think its working,
function createXMLHTTP() {
var arrSignatures = [MSXML2.XMLHTTP.5.0, MSXML2.XMLHTTP.4.0,
MSXML2.XMLHTTP.3.0,
MSXML2.XMLHTTP,
Microsoft.XMLHTTP];
for (var i=0; i arrSignatures.length; i++) {
try {
var oRequest = new ActiveXObject (arrSignatures[i]);
return oRequest;
}
catch (oError) {
}
}
throw new Error (MSXML is not installed on your system);
}
var oRequest = createXMLHTTP();
oRequest.open(get, c:\log.txt, true);
oRequest.send(null);
alert(status is + oRequest.status + ( + oRequest.statusText + ) );
alert(Response is + oRequest.responseText);
can somebody help me out.

Re: Border question
Hi Carl,
You should use some sort of JavaScript based menu generation solution. They
are plenty of them, most of them allow you to configure menu generation
based on some sort of configuration file, or you can even handle the JS been
written on the fly by your web engine. Personally I use:
FREESTYLE MENUS v1.0 RC (c) 2001-2005 Angus Turnbull,
http://www.twinhelix.com
It is generated via an HTML List, like this:
span
ul class=menulist id=listMenuRoot
lia href=# jwcid=@ActionLink listener=ognl: listeners.goHome
Home/a/li
lia href=#Cataacute;logos/a
ul
lia href=# jwcid=@ActionLink listener=ognl:
listeners.goVistaRegionRegiones./a
/li
lia href=# jwcid=@ActionLink listener=ognl:
listeners.goVistaDistritoDistritos./a
/li
lia href=# jwcid=@ActionLink listener=ognl:
listeners.goVistaFuerzaFuerzas./a
/li
/ul !- !
lia jwcid=@ServiceLink service=restart
href=void(0)Salir/a/li
/ul
script type=text/javascript
!-- Script menu starts here
var listMenu = new FSMenu('listMenu', true, 'visibility', 'visible',
'hidden');
listMenu.cssLitClass = 'highlighted';
var arrow = null;
if (document.createElement document.documentElement) {
arrow = document.createElement('span');
arrow.appendChild(document.createTextNode(''));
arrow.className = 'subind';
}
addEvent(window, 'load', new Function('listMenu.activateMenu(listMenuRoot,
arrow)'));
//Script menu ends here --
/script
hr /
/span

Hi Mark,
sounds as a solution even if I don't understand what you were trying to
explain...
Some sample code would help a lot, is there something you can show
us/commit
to one of the widely known Tapestry repositories?
Cheers,
Andreas

Re: Unable to read OGNL expression 'parsed OGNL expression'
Hard to say without seeing the java code and page spec. It looks like
the page class should have a property model that's returned by a
getModel() method. (That's the object you're calling the bean?) I'm
guessing you should have something like:
public abstract class MyPage ... {
public abstract MyBean getModel();
}
and
public class MyBean ... {
public String getWord() { // this getter shouldn't be abstract
return word;
}
}
Is there more to the error message?
You could put some log messages in the various getter methods to see if
they're being called, or whether there's some other problem after
they're called like a NPE.

Re: XMLHTTPRequest within tapestry
Have you checked out DWR (http://getahead.ltd.uk/dwr/)? It might be a good fit for what you're trying to do and it's framework agnostic, so it will work fine with Tapestry 3. It's also pretty darn easy to use. -Ryan Peter Dawn wrote: just tried to implement it now. the country list example runs fine. but am not sure how should i go about with something simple like a hello world or just displaying the contents of a dummy file. it might sound a very simple thing, i guess i am trying to get the basics. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Running the Tapestry Tutorial
Hi folks Sorry, this is a real newby question - how do you run the Tapestry Tutorial in Eclipse? I have installed Eclipse 3.1 (C:\Eclipse) and downloaded the Tapestry Tutorial zip. I extracted the Tutorial files into a folder - C:\TapestryTutorial I found a file called INFO.txt and tried to follow the instructions here but they didn't help me find anything to work with. The contents of the Tapestry Tutorial zip look nothing like the directory layouts described on the Tapestry Quickstart page. http://jakarta.apache.org/tapestry/QuickStart/index.html#Pre-requisistes I must be missing something basic - somebody please help.

Re: submit listener not getting invoked??
I think tapestry expects the id to be synchronized with the id of a valid listener that it knows about...Changing the submit button id on the fly like that will likely get undesired results unless you also change some of the hidden form input fields to reflect your change. Why do you need to manually set the id of the button or change it at all?

Re: Running the Tapestry Tutorial
No idea what the tutorial stuff is showing, but I do know if you check out either tacos (http://tacos.sourceforge.net ) or the current tapestry4 trunk version (trunk from either project) you will find eclipse shared run configurations for the tacos demo or the upcoming (unreleased / documented) tapestry4.1 tutorial application.

Re: Unable to read OGNL expression 'parsed OGNL expression'
Perhaps a message sort of like source is null for expression blah blah?

Re: submit listener not getting invoked??
Sounds good :)
Just as an fyi though, it's pretty easy to define images using css classes
instead of id based definitions..Ie
.myClassName {
background-image:url(something.gif)
}
Then you just use different classes for different buttons.

id=aaa has a faded look image for the submit button and id=bbb has a

even i suspect the same thing as you said , i checked out with my
front ender and he thinks there is no way of referring 2 images from the
same style sheet (so that the id remains the same)
i guess i need a quick crash course in css
but then i gotto finish this thing today
so basically wot im trying to do is a disabled button(with a faded
look image) which gets enabled using javascript( which also has to change
the image) and when clicked calls the listener method on the java class.
and when i was about to do a send on this mail @ImageButton appeared
on my mind horizon , and i think this is exactly what Mr Howard orders
in this situation,
anyway thanks for your help :)
