Greetings to the developers of the lovely framework, tapestry5
Hi!
I wrote a form with a single text field, this field is bound to a string
object. When I enter a single or multiple spaces in this text field and
submit the form, the obtained values is always null.
Check the nulls and translate parameters of TextField in

HowTo break out of a Tapestry loop?
So, i am trying to break out of tapestry loop here.
This is my -more or less- simplified scenario:
ul
t:loop source=firstSource value=firstValue
li
t:loop source=firstValue value=secondValue
p${secondValue}/p
/t:loop
t:loop source=secondSource value=thirdValue
p${thirdValue}/p
/t:loop
/li
/t:loop
/ul
What I do not want to have is: Tapestry loops through all entries in
firstValue - then loops through all entries in secondSource. I do not want
to iterate through secondSource inside the loop of fristValue as this would
iterate through all entries in secondSource - and I just want to do 1
iteration at a time.
What I want to have is: Tapestry enters the loop for firstValue and does
some printing or whatever, then breaks after the first iteration and jumps
into secondSource to do the first iteration . After it has finished it jumps
back to firstValue and repeats these steps. This is what in Java the
break; would do.
I did not find a clue in the Tapestry documentation on how to do this, nor
in the forums.
But it has to be possible in some way. I can not imagine I am the only one
trying to do this.

There is no 'break' in the loop component, but you can wrap your inner loops in a conditional t:if test=.. component. Steve. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Tapestry output with special characters

Re: Tapestry and Clojure
Possibilities for the future: tapestry-clojure might be able to access type hints on the function and use the TypeCoercer to convert method parameters to the correct function argument type. Likewise, it could (and probably should) use the method return type as a guide to TypeCoerce the function return value into the method return value.

Re: Memory Leak
Tapestry has been noted to be effectively free of memory leaks.
What release of Tapestry are you using?
You seem to have a caching service here .. do you ever clear your
cache? Could the contents of your cache account for the memory usage?
Are you checking memory usage after running at least one full GC? If
you aren't running out of memory, Java is happy to let it clutter up
the place.
You can use VisualVM to get an idea of what objects are in memory,
that might help identify what, if anything, is leaking.

Re: a problem about tapestry5's minxins
What have you done so far to diagnose this problem?
For example, if I were dealing with this (I often do) I start by
checking that the page, and the JavaScript, rendered as I expected.
I'd then check the browser console for errors.
I'd also set breakpoints in my JS code to see if and when it is executed.
When debugging, you always want to go from a position of certainty to
another position of certainty. This requires you to gather facts as
you go.

Hi Howard, I'm pretty new to services, so I'm just not sure if I'm using
them correctly. I've had the system go down three nights due to an out of
memory error.
What release of Tapestry are you using?
v5.3.3
You seem to have a caching service here .. do you ever clear your
cache? Could the contents of your cache account for the memory usage?
Nothing in the cache, I've disabled all caching and just let the scheduler
run outputting memory usage.
Are you checking memory usage after running at least one full GC? If
you aren't running out of memory, Java is happy to let it clutter up
the place.
Perhaps I don't completely understand how GC works. I'll read up on this
some more.
You can use VisualVM to get an idea of what objects are in memory,
that might help identify what, if anything, is leaking.
I'll look into that as well. Thanks Howard.

Re: Tapestry 5.3.4-rc-5
If I'm not mistaken, JSR-133 only affects final fields so we still have the same problem for non-final fields. i.e any non-final fields in Messages might still be uninitialized even if the *reference* is visible to other threads (messages != null) Actually, JSR-133 guarantees that final fields are initialised before reference to the object is visible to other threads even not using volatile. Change in 'volatile' was separate: * The semantics of volatile variables have been strengthened to have acquire and release semantics. In the original specification, accesses to volatile and non-volatile variables could be freely ordered. * The semantics of final fields have been strengthened to allow for thread-safe immutatability without explicit synchronization. This may require steps such as store-store barriers at the end of constructors in which final fields are set.[1] [1] http://www.cs.umd.edu/~pugh/java/memoryModel/jsr133.pdf Cezary

Sometimes the value being lazily created is so expensive, it would be
invalid to allow multiple threads to create it. In other cases, more
than one shared field is updated.
Hm, but the second check inside 'synchronized' block is supposed to avoid
creating value on multiple threads. For example:
private volatile Messages messages;
public Messages getMessages()
{
if (messages != null)
{
return messages;
}
synchronized (this) {
if (messages != null)
{
return messages;
}
messages = elementResources.getMessages(componentModel);
// --- only called if no other thread did this before
}
return messages;

What have you done so far to diagnose this problem?
For example, if I were dealing with this (I often do) I start by
checking that the page, and the JavaScript, rendered as I expected.
I'd then check the browser console for errors.
I'd also set breakpoints in my JS code to see if and when it is executed.
When debugging, you always want to go from a position of certainty to
another position of certainty. This requires you to gather facts as
you go.

Re: a problem about tapestry5's minxins
Have you tried firebox or some other js debugger to check if there is an error ?

What have you done so far to diagnose this problem?
For example, if I were dealing with this (I often do) I start by
checking that the page, and the JavaScript, rendered as I expected.
I'd then check the browser console for errors.
I'd also set breakpoints in my JS code to see if and when it is executed.
When debugging, you always want to go from a position of certainty to
another position of certainty. This requires you to gather facts as
you go.

I know I have a memory issue, three mornings in a row the server has been brought down with an out of memory exception, so I first wanted to be sure I was using T-IoC correctly. Your Tapestry-IoC code looks fine. I'd check the cache implementation itself and whether there are some points in your code that allocate too many objects and still have references pointing to them (so they cannot be garbage collected). -- Thiago H. de Paula Figueiredo - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

IMHO, mixins are an advanced concept, so my advice is that you shouldn't try to write your own nor trying to understand now. You're mixing too many things (pages, components, mixins, using JavaScript in Tapestry) to learn at the same time and this bringing you confusion and not knowledge. Before mixins, you need to really understand pages and components. In other words, start from the basics. ;) Regarding your problem, the first thing you need to do, as already said here, is to check for JavaScript errors. Firebug is a very nice tool for that (and lots of other web development too). -- Thiago H. de Paula Figueiredo - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
