Re: Activation context for a component?

[Nathan Kopp]

Hey... I did a little follow-up on this and decided to create an "event-safe
loop" that can restore the state of the loop variable using the page
activation context.  It's not quite perfect, but it's good enough for my
needs right now.  For my application, the resulting code ended up looking
much cleaner than the version that used only the event's context to restore
the state.

It works like this:
1) Replace your  component with   You should specify the
t:id parameter... you'll need to know it for step 3.
2) Provide an encoder for the loop value. This parameter is optional for
 but required for .  However, only toClient() needs to
be implemented.
3) Annotate your loop value with @LoopValue("loopid") instead of @Property,
where "loopid" is the t:id specified for the .

The  component stores the state, and @LoopValue creates a
special getter that can restore the state.

Unfortunately, there are some additional requirements that I'd like to
remove:
1) The loop source cannot be initialized by lifecycle methods (e.g.
@BeginRender), since they won't get called.
2) You must include "@Inject ComponentResources res;" in your component in
order for the code generated by @LoopValue to compile.
3) The underlying page must provide simple (one-line) boilerplate
onPassivate and onActivate methods, which can be provided by inheriting from
a superclass.
4) Care must be taken if you want to also use the page activation context
for other purposes.

So far, this is working very well for my application.  I haven't tested its
compatibility with the formEncode feature of the normal Loop component.  If
other people are interested, I'm willing to share the source code... but I
probably won't have time to provide much support.

exceptions sometimes are omitted completely

[Yury Luneff]

Hello!

I'm  fighting  with  my app for features now. There is a problem about
valueencoders  and  such and i guess this problem should report as any
kind  of  exception  - either the beautiful one done by tapestry or at
least stacktrace in log window.

But tapestry chooses neither. Just empty page and that's all.

Sometime  ago  this  also  happened  a  lot  - one mistake in property
binding  and  you get the right exception sometimes, but sometimes you
get completely nothing.

"Debug" in log4j doesn't quite help here.

Did  anyone  meet  that  behavior?  It  is  very  unpleasant  to debug
something  with  empty pages and no exceptions (log4j, btw, is set for
error level as default which should do exceptions).

Hi Everton, I usually do this kind of things (Properties that change between

[T5.1] Log4j and Application Development/Production Mode

[Everton Agner]

Hi,

There is any T5 Elegant way so I can automatically switch between distincts 
Log4J configurations related to Development/Production Mode? We have the 
@Symbol "productionMode", so I believe there is some way I can achieve that 
using this information...

I saw something like that on an old Struts 1.3 application, so there was a 
log4j.properties file on the project and, on the Deployment Server, other 
log4j.properties (and some weird conf to make it works). So, I could work on 
DEBUG mode on the Development environment, and in ERROR mode on Deployment 
environment without having to change.

I don't want to do that here, though...

Any help would be appreciated.


Thanks!

Everton

Re: ZoneUpdater and Zone Race-Condition

[kamiseq]

you can add mixins to your "a" tags that will get id of the link and href
generated by tapestry, then you can call server from client like any other
resource from your own code. no magic there.

I'm hoping there will be a nice solution, too.

But in the meantime is there any documentation about Tapestrys 
client-side-behaviour? Because i can't imagine what you mean with:

"you can hack it whit your own implementation of the page request through

Of course not. I would have done it myself but did not find the time.

Thank you Stephan this works perfect and it was a big step in my understanding 
of Tapestry. Do you mind if i create a wiki articel out of your code example?

The setup is complex. Follow these steps and let me know if there is
anything unclear:

1. Save controlNames of all fields

If your field has the id "myField", use this code:

-

private Map controlNames;

void onValidateFromMyField(Object value) {
if (controlNames == null) {
controlNames = new HashMap();
}

controlNames.put(paper, myField.getControlName());
}

-

Object is the current value you are iterating over, depending on your
page. Verify in onValidateForm that all controlNames are set.


2. Create your own component SimpleField:



public class SimpleField implements Field {

private String controlName;

public void setControlName(String controlName) {
this.controlName = controlName;
}

public String getControlName() {
return this.controlName;
}

[...]
}



Put it in your tml and inject it in your page code.


3. Use both in onValidateForm

Check the submitted values in onValidateForm. If a field should be
marked, set the controlName of the simpleField and record an error for it.

HTH
