Re: T5: integer input box query
Hi Thiago, Thanks for your suggestion. Yes, the CSS is included correctly. The problem goes away when I use an Integer rather than an int. p. Quoting "Thiago H. de Paula Figueiredo" : Check if the Tapestry CSS file is being correctly included in your pages, because that's the one who hides the red X image when the textfield is rendered without errors. -- Thiago - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Thanks, although everything in my project is working and I'd rather understand how the class reloading works and how I can fix my non-working version than start from scratch.

T5: integer input box query
I have an input box that accepts an int. It is enabled/disabled by a selection from a combobox. Whenever it is enabled it shows a red border and red X next to it, even though the value in the box is correct (and is initialised with a value when the page is initially shown). Here is my mark-up: value="keywordVisual.keyword.proximity" t:disabled="keywordVisual.inverseUseProximity"/> keywordVisual.keyword.proximity is of type "int". Why is this occuring? thanks, p. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
T5: auto class reloading no longer works
A while ago I had a problem with Maven deciding to wreck my Eclipse environment. I managed to fix all the problems, but I noticed class reloading no longer works. It's beginning to drive me insane, having to restart Jetty all the time... Where abouts should I look to get class reloading working again? p. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Partly OT: problems with Eclipse / T5
Nothing much to see... I'm perplexed!
I've fixed all my Maven problems now. So this leaves problem (2) - the
uncatchable exception.
The code in getRecordIdsByKeywordGroupsLC() correctly throws the
exception. The catch never catches it. There is only one exception
class with the name TooManyResultsException. It won't even catch it as
Throwable.
The following snippet is inside my onSuccess() method:
try
{
System.out.println("START SearchResults");
searchResults =
repository.getRecordIdsByKeywordGroupsLC(keywordGroups); // THIS IS
LINE 231
}
catch (TooManyResultsException e)
{
System.out.println("INSIDE TMRException
Handler");
tooManyResults = e.getMaxNumber();
}
Output is:

T5: how to invalidate session on logout?
I need to be able to reset everything when the user logs out. Currently @Persist objects are still available if the user logs in again with the same browser instance. This isn't very optimal. I have searched the mail archive and found some comments on this issue made at the end of 2007. I'm wondering if there is a standard way to do this. The Wiki appears to be silent on the issue - I would have thought this would have had more importance than it seems to have. According to these prehistoric ;-) postings to the mailing list, one should inject RequestGlobals and then call invalidate() on the session. Is this still the way to do this? It seems rather clunky and non-obvious - especially for the novice T5 programmer who is shown numerous examples of logins and ASOs and how to use @Persist. The T5 page about persistance strategies is also silent on the issue (apart from mentioning discardPersistentFieldChanges() - but that would require running the method on every page when logging out). Thoughts? p. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
How to specify onUnload in ?
Hi,
I have a template component that is used by all my pages. I'd like to
be able to specify for one of those pages.
Unfortunately it doesn't seem to matter what way I try I cannot get it
to work.
I can't include a in the page because then there will be two
such tags (Firefox doesn't mind, but IE doesn't recognise the second
body tag - plus it is poor form anyway).
I can't include onUnload in the template because it appears to
just be replaced with a standard tag when the page is rendered.
I can't use any form of ... (which I would have liked to do -
passing the onUnload string into my template and then choosing a
single or parameterised version depending on whether the value
was null) because has to match with and the tag
obviously screws this up.
I can't use t:outputRaw to generate my tag because it won't generate
special characters properly ("<" and ">").
I don't recall having these sorts of problems with Tapestry 3 when I
used it many moons ago. It seems T5 is really rather limited in this
respect.
Is there any way to do what I want? It is rather critical that I can
perform onUnload.
thanks,

Let your handler method return a StreamResponse object.

Hi,
possibly not Tapestry specific and I'm not knowledgable enough on this
subject, so apologies.
I would like to be able to display a PDF that I obtain from a database
using Hibernate via Tapestry. Is there a way to stream the data?
thanks,

Re: [T5]: query regarding streaming data
Thanks Olle,
However, reading the docs I see that the Streaming applies to
components. In my situation I need to open a new window, which I
currently do with JavaScript (in this example I'm obviously opening a
local file, but as I said, in the real version it needs to come from
the DB):
e.g.:
Open a PDF
which is so I can auto-close the window:
function openPdf(url)
{
windowprops = "left=10,top=10,width=1000,height=1100";
if (ChildWin)
{
return false;
}
ChildWin = window.open(url, "ChildWin", windowprops);
ResetTimer();
if (TimeOut && RefreshRate)
{
setTimeout("CheckClose();",RefreshRate * 1000);
}
}

Re: T5: how to detect session timeout?
Thanks Peter.
The problem was in the dispatcher code that disassembles the URL. The
code that I grabbed from the wiki (as I recall) checks for / but
doesn't account for . when attempting to obtain the page name. While
I've had a security dispatcher working for some time that uses that
code, this version was not working because when clicking on a link the
path is of the form: ftpaccess.changedirectory/pub (when I needed the
page called ftpaccess).
All fixed now and works as expected.
p.
Quoting Peter Stavrinides <[EMAIL PROTECTED]>:
I use a RequestFilter instead of a dispatcher to achieve same
thing... but it should work just the same for you (before:PageRender
is fine). In your dispatcher you need to check your state object
for null and redirect to your login page.
For example:
if(applicationStateManager.get(SiteSessionAccess.class) == null){
response.sendRedirect(loginPage);
return true;
}
Short-circuits the page load.

Subject: T5: how to detect session timeout?
Hi,
I am trying to deal with session timeouts in T5.
Rather than extend a base class I was hoping I might be able to use an
Annotation. However, I find that when the user activates a link or
presses a button on a timed-out session that the dispatcher is not
being called early enough to detect anything and I end up with a null
pointer exception.
I have the following in my AppModule:
configuration.add("TimeoutDetector", timeoutDetector,
"before:PageRender");
Two questions:
a) is it possible to detect Session timeouts in this way?
b) As PageRender isn't early enough can I hook this in earlier? I'd
also appreciate knowing what values can be placed in that parameter.
Nowhere can I find this documented (apart from a reference to
"before:" and "after:"). I've even looked in the T5 code but I'm
afraid there is just too much of it to look through. Surely the
specification of part of a page lifecycle would be better as something
other than a String?!
thanks,
p.

T5:Pages now broken under 17
Hi, I've just moved from 5.0.15 to 5.0.17. I now find I get this: Render queue error in BeginRender[Administration:pagelink_1]: Error persisting field SearchMetadata:allKeywords: Persistent fields may not be updated until after the page has finished loading. This may be due to a persistent field with a default value. The default value should be removed. I want to initialise various things and I'm afraid some of those things are persistant fields. My current code has these in the constructor for the class. Even if I change this to a method and use @PageLoaded it still doesn't like it. Where are persistant fields now supposed to be initialised?

Re: Tapestry 5, WAR files and deployment
Thank you Olle and everyone else who replied to my query. Indeed, I had to recreate the repository (plus I missed one or two dependencies). p. Quoting Olle Hallin <[EMAIL PROTECTED]>: The standard cure-most-dependency-problems medicin for Maven is to wipe your local repository and try again. Delete (or rename) $HOME/.m2/repository (Linux) or %USERPROFILE%\.m2\repository (Windows). Also: the standard way to package a any Maven project is mvn package. mvn war:war happens to work here, since it is bound to the package goal for a war project. HTH, Olle 2008/11/6 Fernando Padilla <[EMAIL PROTECTED]> This is probably because it can't download the files.. I would double check your networking, but because you're emailing us I'll assume it's working. Someone I know also had issue like this, and the cause for him was he installed it as root on his laptop, so when he tried to build it as his user he didn't have permissions to actually modify the repository. So it could not successfully fetch any dependencies. Though I don't recommend it, he runs all maven with sudo. Not sure what the best way to install it is, but I installed maven on my laptop simply by extracting it into a directory as my user, then adding the bin directory to my user's path.. tapestryphoto wrote: Quoting Olle Hallin <[EMAIL PROTECTED]>: Does it work from the command line?

Re: T5: cannot use Grid's rowIndex in page class
By chance I used one for the first time this-morning.
I have:

...

(which is the only difference I can see between your code and mine)
and see what happens.

I see that it is supposed to be available from 5.0.15 (

cannot make it work.
From my template:
and from my page class:
private int _rowIndex;
public int getRowIndex() {
System.out.println(">>> getRowIndex(), _rowIndex = " + _rowIndex +
")");
return _rowIndex;
}
public void setRowIndex(int index) {
System.out.println(">>> setRowIndex(" + index + ")");
_rowIndex = index;

but the getter and setter are never called - not during render and not
during form submission. Any ideas?

Re: T5: help required: Context and PageLink
Thanks Tobias!
Quoting Tobias Wehrum <[EMAIL PROTECTED]>:
Hi,
the problem is not your pagelink, the problem is your stylesheet link.
When it trys to load, it seems to search in "viewMetadata/style.css",
thus being passed as an activation context which of course cannot be
coerced to long.
Anyway, in my opinion the best way to pass the stylesheet is the
@IncludeStylesheet-Annotation.
@IncludeStylesheet("context:/style.css")
class ViewMetadata {
[...]
}
An alternative and something you might need when including images, for
example, is by using Assets:
viewMetadata.java:
@Inject
@Path("context:/style.css")
@Property
Asset cssFile;
viewMetadata.tml

Re: [T5] editing a looped list of objects' properties in a form
Quoting Andy Pahne <[EMAIL PROTECTED]>: That were our web designers. But it worked that way in many other form components. So I did not think about it any further. Anyway, I tried . There's no difference in the behaviour, regardless of which type of Submit is used. I think you might find (as I did - see my 2nd original posting on this issue) that the objects being updated in the loop are different instances to the ones that are specified. It seems to be a serialization problem (but that's a guess on my part - I don't know what the Tapestry code does). I think a bug should be raised for this issue. p. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [T5] editing a looped list of objects' properties in a form
My understanding is the "additional configuration" is in using an encoder. If you have simple serializable objects (like I do) then it should just encode them automagically in the form. If you have complex objects then you need to write an encoder so only, say, object ids are encoded in the form. p. Quoting Andy Pahne <[EMAIL PROTECTED]>: It should work somehow, at least the documentation says so: http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Loop.html (at the very end of the page). Quote "Tapestry form control element components (TextField, etc.) work inside loops. However, some additional configuration is needed to make this work efficiently. " Unfortunatly it does not say what "additional configuration" is needed to make that work. Andy tapestryphoto wrote: This looks similar to my problem (see both of my posts from a day or so ago).

This looks similar to my problem (see both of my posts from a day or
so ago). It appears Loops in a Form do not update the properties.
Perhaps this is broken in Tapestry. I guess it must be a bug.

I am trying to edit the properties of objects contained in a list by
using a loop in a form component. But it does not work, because the
objects in the list are not updated.
The list of passengers:
@Property @Persist
private List passengers;
This list is initialized like this:
@BeforeRenderTemplate
public void initialize() {
int passengersTotal = getQuery().getPassengersTotal();
if(passengers == null) {
passengers = new ArrayList(passengersTotal);
for (int i = 0; i < passengersTotal; i++) {
passengers.add(new Passenger());
}
}
}
I try to buid a form in order to edit the passengers like this:
${message:firstName-label}
Unfortunatly, after a successful submit, the firstName property is not
set for any of the passengers contained in that list. I veryify that by
the following logging statements:
public void onSuccess() {
int passengersTotal = getSearchOptions().getPassengersTotal();
for (int i = 0; i < passengersTotal; i++) {
System.out.println("Passenger '"+i+"'" + ": " +
passengers.get(i).getFirstName());
}
}
which always produces the output:
Passenger '0': null
Passenger '1': null
I thought that this would be the way to go, but I must be wrong
somehow. Could anybody tell me what's the correct pattern to use here?
Thank you,
Andy

T5: Query about BeanModel
Am I correct in thinking that the default BeanModel only recognises the standard property types (String, double, etc, etc)? I have a bean with several properties, one of which is one of my own types. When I attempt to use this bean in Grid I am unable to specify the property in the include list. If I specify that particular property an error occurs and claims that the property does not exist (and it does not appear in the list of available properties). p. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: looping in form not updating values
I should add that replacing the Loop with a Grid causes it to work as
expected. Also, I notice that when I use a Loop, the setValue() being
called is on a different instance of Keyword than the one used by the
getter. As new is only called once, I gather the object used by the
setter must be being created by the serialization mechanism.
Any further thoughts appreciated as this has me stumped.

Hi,
Bit of a simple query. I'm not sure what I'm doing wrong as I've
followed the example given in the T5 component reference (bar using an
encoder - my values are strings so I don't see why I should need one).
I'm trying to implement a dynamic form where a user can add extra
keyword fields. Adding works fine. Unfortunately when the form is
submitted on Search none of the keyword values are updated with the
entered values.
Here is the markup:
Tag:
Keyword:
Here is the page class:
public class SearchByTag
{
@SuppressWarnings("unused")
@Property
@Persist
private GenericSelectModel tags;
@SuppressWarnings("unused")
@Property
@Persist
private Tag tag;
@SuppressWarnings("unused")
@Property
@Persist
private List searchResults;
@SuppressWarnings("unused")
@Property
@Persist
private Value listItem;
@Property
@Persist
private List allKeywords;
@Persist
private Keyword keyword;
@Inject
private PropertyAccess propertyAccess;
@Inject
private MetadataRepository repository;
public SearchByTag()
{
List list = repository.getAllTags();
allKeywords = new ArrayList();
tags = new
GenericSelectModel(list,Tag.class,"name","id",propertyAccess);
}
public GenericSelectModel getBeans()
{
return tags;
}
void onSelectedFromAdd()
{
allKeywords.add(new Keyword());
}
Object onSuccess()
{
for (Keyword x: allKeywords)
{
System.out.println("VALUE > "+x.getValue());
}
return this;
}
public Keyword getKeyword()
{
return keyword;
}
public void setKeyword(Keyword keyword)
{
this.keyword = keyword;
}
}
