Dynamic mixins
Hi all,
have a problem that seems easy to resolve but I'm making hard work of
it, was hoping someone here can help me out. I have a simple component
I want to use on different pages in my application, and there's a
mixin associated with the select component in this simple component,
but I want to use a different mixin depending on which type of page
the component is located.
so I have in my component.tml
and in my component.java
public String getMixin() {
if (getContainer() instanceof SendMoneyTransfer) {
return "feefromresidentupdater";
}
return "singlesourceformfieldupdater";
}
getting "Unable to resolve 'mixin' to a mixin class name". Have tried
prop:mixin, ${mixin}, ${prop:mixin} etc. to no avail, would like to
avoid having multiple select components with different mixins and an
if else(s) if possible?
Thanks for listening! Brian.

Re: Exception handling in Tomcat 6.0.33
Hi Kalle, yes I managed finally track down the answer after searching through pages of search results, unfortunately my original search query included the terms "tomcat", "tapestry" and "error" which produces reams of result (most of them irrelevant)! Like you mentioned in your reply I needed to add an error dispatcher (like example here: http://tapestry.apache.org/error-page-recipe.html) app /* FORWARD REQUEST ERROR I then mapped error codes to tapestry URLs 500 /ExceptionReport 404 /ExceptionReport Tomcat then started to redirect these error types to my Exception Report page like Jetty already does. Hopefully this answer will be found by the next person looking into this issue. Thanks for the link explaining why the tapestry exception report filter works in Jetty but not in Tomcat . . .

Exception handling in Tomcat 6.0.33
Hi all, I'm sure I'm not the first person to experience this issue but can't seem to find any answers in the mail archive or on the web. I have an ExceptionReport page implementing ExceptionReporter so any nasty surprises like NPE's result in a nice and friendly "We experiencing technical difficulties" page being presented to the user, this works fine in jetty but when I deploy my war file to tomcat 6, the exceptions are not caught by the ExceptionReporter and the stacktrace is shown to the user? If anyone know what setting in tomcat needs to change so I can get this to work as it does in jetty I appreciate it.

Re: property expressions
Hi Thiago,
thanks for the quick reply, I'd already seen the official tapestry
property expressions page but as there's no examples given there I was
hoping there was something else buried in one of the wiki pages?
I'll take your advise and move this logic to the java class, I'm going
to have a lot of helper methods for the logic that was attached to the
various fields on my form, but I guess I can't be avoided.
Regards, Brian.

Oops!
I'm currently using

I might try changing the javaassist to an older revision to see it

Property expressions
Hi all,
just a quick question, looking at the property expressions guide @
http://tapestry.apache.org/tapestry5/guide/propexp.html it looks like I
should be able to evaluate whether a property has a null value (handy
for if conditions) without having to use ognl,
e.g. instead of
${message:EXPORT}
I should be able to use the property expression directly, there's a null
keyword and an notOpt !, but what is the proper synthax?
Regards, Brian.

using prop: binding to evaluate an expression?
Hi,
in tapestry 4 you could use ognl to check a page property in a
expression like disabled="ognl:!nextAvailable" or ognl:(nextAvailable ==
false)", I'm wondering is we can do something similar in T5 without
using ognl, just using the prop: binding prefix alone, for example
public final boolean isNextPageAvailable() {
return true;
}
the above example doesn't work of course, as there's no property named
"!(nextPageAvailable)" just nextPageAvailable . . .
Regards, Brian.

localization of keys returned as properties in T5
Sorry about the ambiguous title, but I'll try to explain what it is I'm
trying to achieve . . .
in T4 it's possible to have properties/keys in an object that can be
localized in the html file using the following expression
AddressLine1
tapestry will resolve what the contents of "sender.address.addressLine1Label"
are before trying to find a match for that key in the appropriate
.properties file.
however in T5 we no longer have ognl: prefix (I'm guessing it's replaced by
prop:?), so I tried (unsuccessfully) using certain combinations of the prop:
and message: prefix to first extract the key from the required object before
trying to localize it. The only solution I could come up with was to inject
the messages bean into my class and add a method that can pass the key into
my messages bean and return the localized text. This method is then called
from the .tml. Ideally however I would like to find a way to do all of this
work in my .tml file, so if anyone has any ideas, comments or criticism,
please let me know.
Regards, Brian.

Form names in T4.1
Hi all, this is just a quick question, in previous versions of tapestry a Form was assigned a name using the convention jwcid="[EMAIL PROTECTED]", however in T4.1this no longer sets the name but assigns an id="someName". Question is, how do I assign a name to my Form component in 4.1, as informal parameters are allowed but name is reserved? Regards, Brian.
Re: Re: dynamic image assets?
Guys,
I'm ashamed to admit that my problem was a classic case of RTFM, as there
was an example on the tapestry web site that fixed my dynamic Image asset
problem with just a few lines of code.
I placed my subscriberImage component on my page, and then added the
relevant method to my class:
public IAsset getSubscriberAsset() {
String pathToImage = getSubscriber().getPathToImage();
return new ExternalAsset(pathToImage,null);
}
Problem solved! Thanks again for all your helpful suggestions,
Regards, Brian.
Re: dynamic image assets?
Gareth, while storing the images in the databases is a possible(?) solution, it's one I'd like to avoid for the time being as I want to keep my database size as small as I can, therefore I just want to store the paths to the files for now. Christian, the "pathToImage" returned by my subscriber dataobject is exactly that, a path to the image. I'd like to use this in the asset component instead of the path: but the asset doesn't evaluate ognl expression, it's looking for a string full stop. I've tried to move the Asset from the .page into the class itself but I still get the same problem, the string for path has to be a constant, variables are not allowed. Brian.

Re: DirectArea component in Tapestry 4
Hajaansh,
had the same problem myself when moving from 3 to 4, so here are the updated
AreaLink.jwc and AreaLink.java that I use. The main difference in the use of
property injection for the engine service.
AreaLink.jwc
http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd";>
Creates a non-contextual link. Non-persistent state can be stored within
the link
using the context.
An object, or list of objects, encoded into the URL
as service parameters.
AreaLink.java
package com.annadaletech.yourProject.web.jwc;
import org.apache.tapestry.AbstractComponent;
import org.apache.tapestry.IActionListener;
import org.apache.tapestry.IDirect;
import org.apache.tapestry.IMarkupWriter;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.Tapestry;
import org.apache.tapestry.annotations.InjectObject;
import org.apache.tapestry.engine.DirectServiceParameter;
import org.apache.tapestry.engine.IEngineService;
import org.apache.tapestry.engine.ILink;
import org.apache.tapestry.link.DirectLink;
public abstract class AreaLink extends AbstractComponent implements IDirect
{
public abstract Object getParameters();
public abstract IActionListener getListener();
@InjectObject("engine-service:direct")
public abstract IEngineService getDirectService();
public void renderComponent(IMarkupWriter writer, IRequestCycle cycle)
{
if (cycle.isRewinding())
return;
Object[] parameters = DirectLink.constructServiceParameters
(getParameters());
//IEngineService service = getDirectService();
DirectServiceParameter dsParam = new
DirectServiceParameter(this,parameters);
ILink link = getDirectService().getLink(false,dsParam);
writer.beginEmpty("area");
writer.attribute("href",link.getURL());
renderInformalParameters(writer,cycle);
}
public void trigger(IRequestCycle cycle)
{
IActionListener listener = getListener();
if (listener == null)
throw Tapestry.createRequiredParameterException(this, "listener");
listener.actionTriggered(this, cycle);
}
public boolean isStateful()
{
return false;
}
}
hivemodule.xml
yourProject.application
I hope this helps . . .
/Brian.

I was wondering how to make a DirectArea component (getting callbacks on
Image Maps) for Tapestry 4 as the implementation for Tapestry 3 does not
work in Tapestry 4.
And clues? I was looking at using the ILinkRenderer but to be honest I am
just getting in a muddle.

Re: multiple stylesheets
Nick, that worked perfectly, thanks! I just had to change a few things for it to comply with T4, but unfortunately now I'm faced with another problem, there's no titles on my stylesheets. Border.html Border.jwc gives me: but I'd like: So as I can select them on the fly from my browser's view->use style setting. If you or anyone else has already figured out how to do this I'd like to hear how it's done. Thanks again, Brian. On 9/1/06, Nick Westgate <[EMAIL PROTECTED]> wrote: Hi Brian.

multiple stylesheets
Hi all, I'm afraid I might have dug myself into a hole (again!), but I hope someone my have already encountered this problem and is willing to let me know of a possible solution. I'm trying to add multiple stylesheets to my web project, I'm currently using a @Shell component to enclose my web pages, this has a single stylesheet as per the example on the tapestry website. I want to add some more, and according to the component description there's a parameter "stylesheets" that will take an array of IAssets, this is want I'd like to do, the only problem is that my shell in inside a custom @Border component. Soo, I have a Border.html and Border.jwc and I have to try and create an array of IAssets (my list of stylesheets). How do I do this, create a Border.java? Any suggestions would be much appreciated . . . /Brian.
