Re: createReadOnlyBindingException help!
Hi Andy,
I do not agree, it's not just a documentation problem I've opened a
bug for the specific Dialog problem:
https://issues.apache.org/jira/browse/TAPESTRY-1699
I think default use just doesn't behave the way you expect it to
behave (that is a bug, even though a minor one).
But I think there's also a generic enhancement to parameters that
could be made that I describe in
https://issues.apache.org/jira/browse/TAPESTRY-1700
I think this could provide a new interesting feature and many
misunderstanding like the one me and Andrea (I guess) had.
If you think it's useful I could provide some code

Anyway, I think we should just document this.

Finally I think we were both wrong and that I opened two useless tickets:
in fact, as stated in the documentation default-value attribute now
accept any kind of binding and actually CREATES the binding if no
other binding is present.
In your case:
org.apache.tapestry.binding.AbstractBinding.createReadOnlyBindingException(
AbstractBinding.java:115)) when I call into my rewindFormComponent method
this code:
setStartRow(sliderValue);
and I set into jwc file:
parameter name=startRow required=no cache=true
default-value=ognl:0/
means that at some point, during rewind, some of your code/components
is calling a setStartRow to update the binding but the binding is
invariant (ognl:0 is a costant!) so it's a read only binding (you
can't change the value of a constant) so the
ReadOnlyBindingException is correctly throwned.
What you should do (if you really need to change the bound value) is
bind to a containing component method (e.g. value=ognl:currentRow)
that will contain the logic of when to return the default value and
when not to.
It's also possible NOT TO BIND the parameter by default, initializing
the parameter method after the component finishLoad() phase, in your
case it would be:
In jwc:
parameter name=startRow/
In component:
public void finishLoad() {
super.finishLoad();
setStartRow(0);
}
The fact is that default-value with invariant values (literal,
ognl:constant, ecc.) make sense just if it's a read only binding, At
the same time default-value with ognl expressions referring to
containing component methods would break component encapsulation
making assumptions on the exact method signature the containing
component should implement (also its optional/default status would be
questionable...).
As for my specific Dialog component problem I think there's still a
bug because the component IS actually trying to write the invariant
default-value binding in hide/show methods so after 2 invalid ticket I
hope I'm goig to open a valid one now.

It seems that if you set a constant value (ognl:0 or true) to a
parameter then the parameter itself is regarded as Invariant by
AbstractBinding that will refuse you to use any setter on it (it does
not have a reference to a method but to a... constant) and throw the
exception.
I don't have the exception if I just override the constant default
value with an ognl reference to a couple of setters/getters method
(returning the default value in case the property is not initialized).
In my opinion this is a bug with parameter but I haven't been able
to investigate more and I'm quite surprised nobody stepped into this
problem before, see my neglected Dialog mails of some days ago :-)

Re: [T4.1]Returning a list to a page
You'll have a property for the list in page A and an abstract setter for this property. So now in page B just inject page A using the @InjectPage annotation, call the setter for this list and return the page object in your listener method. Or use the PropertyUtils.write(pageObject, propertyName, valueObject) method in the org.apache.hivemind.util package.

Re: [T4.1]Returning a list to a page
Hello Paolo,
page a should hold an (persist) abstract getter and setter for the list,
page b hold a persist abstract getter and setter for the name of the
calling page which is set when page b is accessed and maybe reset if
needed in the button's listener.
When you are done with compiling your list on page be and the button is
pressed, do something like the following in the button's listener:
(page b)
public void buttonListener(IRequestCycle cycle) {
[...]
IPage page = cycle.getPage(getPageNameOfA());
page.setList(composedList);
[...]
cycle.activate(page);
}

Re: [T4.1]Returning a list to a page
Thanks Uli, only problem is that i was planning to call page B from different pages, so i dont know which one to inject. Maybe will try the PropertyUtils.write, even if it seems to be a little unsafe (does not assure that the property exists in page A when compile).

Re: [T4.1]Returning a list to a page
And you are right, actually i cant make it working.
It seems that IPage is not serializable, so i cant use the
@Persist(client)
The problem using a string is that, when i return the string from my onOk
listener, the calling page A is activated, but after the return statement
it is too late to set the property we are talking about.
What am i missing?

Re: createReadOnlyBindingException help!
I'm not against 1699 at all!
I'm just saying that it's also a documentation problem
As for 1700, I think the traditional way of doing something like that

i'm not sure if what you're suggesting will help or confuse users -

Re: [T4.1]Returning a list to a page
If I got right what's your case you could use the following pattern:
public interface CalledPageCallback extends ICallback {
public void setMyObject(MyClass myObject);
}
public class CallingPageCallback implements CalledPageCallback {
private MyClass _myObject;
public void setMyObject(MyClass myObject) {
this._myObject = myObject;
}
@Override
public void performCallback(IRequestCycle cycle) {
Defense.notNull(cycle, cycle);
CallingPage page =
cycle.getPage(CallingPage.class.simpleName());
page.setNeededObject(_myObject);
activatePage(cycle,page);
}
}
public class CalledPage extends BasePage {
@Persist(client)
public CalledPageCallback getCalledPageCallback()
public abstract void setCalledPageCallback(CalledPageCallback cb)
public abstract MyClass getSelectedObject();
public abstract void setSelectedObject(MyClass selectedObject);
public void onSubmit(IRequestCycle cycle) {
callback = this.getCalledPageCallBack();
callback.setMyObject(getSelectedObject());
callback.performCallBack(cycle);
}
}
Obviously when calling the CalledPage from the Calling page you'll
have to set the callback but at the same time you can have other
implementation of CalledPageCallback used from other different calling
pages.
We have used this pattern with success on our application, hope it can
be of some help.

Re: [T4.1]Returning a list to a page
I'm not sure if I understand that correctly... I think the idea was
not return the page name as a string from a submit method, but to set
it..
in page A:
- inject page B
- set the name of page A as a property in page B
- activate (or redirect to) B
in page B:
- do not inject page A, but get it by name through cycle.getPage..
- set the list as a property in page A
- activate (or redirect to) A
To add to the confusion.. if you access that list from many pages,
wouldn't it be better to store it as an application state object
(ASO)?

page a should hold an (persist) abstract getter and setter for the
list,
page b hold a persist abstract getter and setter for the name of the
calling page which is set when page b is accessed and maybe reset if
needed in the button's listener.
When you are done with compiling your list on page be and the button
is
pressed, do something like the following in the button's listener:
(page b)
public void buttonListener(IRequestCycle cycle) {
[...]
IPage page = cycle.getPage(getPageNameOfA());
page.setList(composedList);
[...]
cycle.activate(page);
}

Hi all,
got a bit blocked here: i need to return a value to the invoking
page.
Page A calls page B -
in Page B I select a list of item from a longer list
when I press OK on page B, the browser returns to page A where the
list
is
set according to the selection made.
I can set the returning page but cant find a way to set there the
value
to
return.
I tried different ways but cant find a solution.
Any help ?
Paolo

Re: createReadOnlyBindingException help!
You mean you could do something like
property name=hidden initial-value=true /
parameter name=hidden/
?? (don't think so).
Or you just refer about playing with properties and paramters?
I know there are other ways to achieve 1700 but I thought an
initial-value might be clearer, just because it seems to me that
also the creatot of Dialog got confused with that :-)
To me that default-value instead of default-binding was very
confusing and I think it was the same kind of confusion.
Well, let's see if anybody think this is interesting, otherwise it was
just a good occasion for me to have a look at wonderful Tapestry code
:-)

In your case:
org.apache.tapestry.binding.AbstractBinding.createReadOnlyBindingException(
AbstractBinding.java:115)) when I call into my rewindFormComponent method
this code:
setStartRow(sliderValue);
and I set into jwc file:
parameter name=startRow required=no cache=true
default-value=ognl:0/
means that at some point, during rewind, some of your code/components
is calling a setStartRow to update the binding but the binding is
invariant (ognl:0 is a costant!) so it's a read only binding (you
can't change the value of a constant) so the
ReadOnlyBindingException is correctly throwned.
What you should do (if you really need to change the bound value) is
bind to a containing component method (e.g. value=ognl:currentRow)
that will contain the logic of when to return the default value and
when not to.
It's also possible NOT TO BIND the parameter by default, initializing
the parameter method after the component finishLoad() phase, in your
case it would be:
In jwc:
parameter name=startRow/
In component:
public void finishLoad() {
super.finishLoad();
setStartRow(0);
}
The fact is that default-value with invariant values (literal,
ognl:constant, ecc.) make sense just if it's a read only binding, At
the same time default-value with ognl expressions referring to
containing component methods would break component encapsulation
making assumptions on the exact method signature the containing
component should implement (also its optional/default status would be
questionable...).
As for my specific Dialog component problem I think there's still a
bug because the component IS actually trying to write the invariant
default-value binding in hide/show methods so after 2 invalid ticket I
hope I'm goig to open a valid one now.

Re: Memory leaks in Tapestry 4.1
We've run into this problem on a production system. It was a not a
good situation. One of our developers narrowed down the issue to
Hivemind. There is some Map that continually grows and grows (I can
speak to our dev to get more detail). After some research into similar
posts it became evident that this issue was brought up to HLS, but the
bug's existence was denied. We've since dropped Tapestry for mission
critical apps. I'm hoping this is no longer an issue in future
versions of Tapestry, but time will tell.

Re: Memory leaks in Tapestry 4.1
I have used both Tapestry and HiveMind under high production loads and have never found any memory leaks in the frameworks themselves. This includes memory intensive, high volume workflow and image processing applications for large financial institutions. However, nearly every application I have worked on has experienced memory leaks at times, often times severe. Sometimes it was my own code. Often it was 3rd party libraries like caching frameworks (ehcache constructs had a badly leaking MutexCache implementation - fixed last year), dao frameworks (iBatis had an LRU cache which did not properly invalidate every other expired entry - also fixed), JDBC drivers (just worked with a version of an AS/400 driver which leaked live a sieve - recently fixed), and the JDK (StringBuffer in 1.4 anyone? - how about using Java 2D?). My experience tells me that if you haven't run your application through JProfiler and looked for leaks, there is a *very* good chance your app is leaking memory, often times in unexpected places. Just because your application is a Tapestry application does not mean the leak is caused by Tapestry - odds are against you on that. My suggestion would be to run your application under JProfiler and put some load on it. It is very simple to do. Watch the heap telemetry and see if it grows monotonically. Watch the object allocations and sizes for the same. If you have some empirical evidence to support a suspected leak in Tapestry, then present it here. I assure you Jesse and the other developers would be eager to fix them.

[4.0] session expiration
In Tapestry 4.0.2, what controls the session expiration, and how can it be increased? Thanks, Ed
Re: [4.0] session expiration
In Tapestry 4.0.2, what controls the session expiration, and how can it be increased? The session timeout specified in your web.xml as in any other webapplication. Your visit object is just placed in the http session.

T4: Client urls for listeners?
In a component class, I need to be able to generate a client URL to put into a JSON object that links to a server-side listener method. Didn't see this in the wiki or first search in mailing list. Ideas? Bill
Re: Memory leaks in Tapestry 4.1
There is an excellent tool for post-mortem memory analyzation: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/d0eaafd5-6ffd-2910-019c-9007a92b392f. Just add -XX:+HeapDumpOnOutOfMemoryError to the startup parameters of your JVM. This will produce a memory dump when your JVM dies because of an OutOfMemoryError. With the memory analyzer you can see which objects consumed all the memory and find out the cause for the the garbage collector not collecting them. (See the corresponding documentation and the wiki to find out how to do this.) Todd Orr wrote: True enough. I'll get more details from our side.

On 8/9/07, Jesse Kuhnert [EMAIL PROTECTED] wrote: Whatever this mysterious issue is that you seem to think exists it'd be impossible to fix whatever memory leaks you think you have found without knowing about them. There is a map that grows as large as the system using it internally to javassist of various cached reflection info - but it doesn't leak in any way. Anyways, vague comments with no specific versions or specific issues that you have faced don't really help anyone.

There is some Map that continually grows and grows (I can speak to our dev to get more detail). After some research into similar posts it became evident that this issue was brought up to HLS, but the bug's existence was denied. We've since dropped Tapestry for mission critical apps. I'm hoping this is no longer an issue in future versions of Tapestry, but time will tell. On 8/9/07, Jesse Kuhnert [EMAIL PROTECTED] wrote: Tapestry 4.1.2 has no memory leaks.

Re: T3: How to capture time
Search the list for old posts (2004) about DateTimePicker. The component jar is still here, I believe: http://myworkspace.sourceforge.net/component-library.html Cheers, Nick.

Re: T3: How to capture time
The Calendar component on tassel also wraps (a newer version of) the same js calendar that DateTimePicker wraps. But the component as written in tassel doesn't do the time. Some time ago, I took it and revamped it somewhat for my own needs to allow for time selection as well as date selection, and also allow for choosing which theme to use. I sent the changes back to the original usc_calendar component author (at least, I'm pretty sure I did... if he's around and I'm wrong, let me know and I'll send them. This was many moons ago. ;) but I don't think they ever got incorporated into the version on tassel. If you're interested, shoot me an e-mail off list and I'll send you what I have.
