visit objects swapped between requests on high load
On this high christmas server load, the most rare problems seem to face at a higher rate... The worst one is that with our tapestry app (4.0), on rare occasions on concurrent requests (really concurrent, on the apache logs they show with 1s difference) from different users, the ASOs get swapped between requests from different users!!! In Tapestry 4.0 most internal services seem to be have singleton instances in the engine with very few threaded services. Could this affect concurrent requests being executed *at the same time*? Any chance this could come from Tomcat/JK? Anyone heard of such issue (tomcat 5.5.17)? -- Henri Dupre Actualis Center

Re: PropertySelection populated from database
yes, this is the case if you use list index as value in your model. This should only be done if you know the list will not change across requests. If it does, use a databse primary key, and reload the entry from the database on the translate method in the model.

For example, if the user selected 'US', Mexico gets added, and user submits the form, 'Mexico', not 'US' gets submitted.

Re: Re: JSR-168/268 support and Tapestry 5.0
hi konstantin,IMHO portlets are going to get more and more important. if you lookat the new portlets 2.0 spec you will see AJAX defined to reload portletcontent, an event mechanism to notify one or more portlets, a new interportlet communication protocol, central session handling aso. With this spec (still in public review) it will be possible to write portals that behavelike "web 2.0" sites but in fact are composed of different web apps.Portlets serve as THE integration API to combine different web applicationsinto a single one. A scenario may be in a big company that already uses 2 (or several) web applications to cover their processes (written in different frameworks). They may conclude that the processes could by better supported if the users had parts of both applications configured into one workbench to see dependencies and impacts immediatly. Thats where portlets 2.0 comes into play :)so i think an integration of Tapestry 5 with portlet 2.0 is necessary )g,krisAn: Tapestry users users@tapestry.apache.orgVon: Konstantin Ignatyev [EMAIL PROTECTED]Datum: 29.12.2006 10:15PMThema: Re: JSR-168/268 support and Tapestry 5.0does it make sense at all to support portals?

browser handling of amp;
Hey guys,
I hope this is an easy fix that someone already stumbled upon already...
I keep getting amp; appeared in the browser address bar, instead of
html code:
input type=button value=Do Something onClick=serviceLink()
script jwcid=@Any type=text/javascript
function serviceLink() {
window.location='span jwcid=@Insert
value=ognl:serviceURL/';
}
/script
java code:
public String getServiceURL()
{
ILink link = this.getSomeEngineService().getLink(false, new
String[]{someparam1});
return link.getAbsoluteURL();
}
I'm confused on why isn't the browser converting amp; = ?

Re: tapestry-spring and tapestry-flash for 4.1?
I wish Maven had a versionwhatever-is-handy/version.
I'll find some time this week to push out a 1.0.0 version of the flash and
spring. They haven't changed in a long while. However, I think they should
still default to Tapestry 4.0.1, since 4.1 is not stable yet (and I haven't
tested them against 4.1, I've been busy coding 5.0).

Re: tapestry-spring and tapestry-flash for 4.1?
Is it possible to upload a new bundle for the latest 4.0.x with an
org.apache.tapestry groupId? Also, you can do a redirect from
tapestry/tapestry to org.apache.tapestry/tapestry? Here's an example from
ehcache:

RE: visit objects swapped between requests on high load
We struggled with a similar bug during load testing of our last release. It turned out to be a non-static anonymous inner class of a page class being put into session. This inner class was calling the getter for an injected state object on the outer page class. Non-static inner classes hold an implicit reference to the instance of the outer class in which it was created. If the timing was exactly right, a user would end up getting the still-cached state object from a page that was still in the page pool (the generated code for a state injection caches the object like any other property, and like any other property the cache isn't reset until the page is attached). I'm not sure that all made sense, but look out for non-static inner classes of pages. If you pass them outside of a particular page instance, you have to remember that any calls to the outer class methods are going through a reference to the creating outer class instance. If that outer instance is in the page pool, it hasn't been cleaned up from the last request and may return old data. Other than that, we've had no instances of crossovers like you're talking about. jeff From: Henri Dupre [mailto:[EMAIL PROTECTED] Sent: Sat 12/30/2006 12:24 AM To: Tapestry users Subject: visit objects swapped between requests on high load On this high christmas server load, the most rare problems seem to face at a higher rate...
