MyFaces CODI and Weld 1.0.1
Hey all, we are currently developing an application based on Weld 1.0.1 and MyFaces CODI. Unfortunately we have some strange problems regarding CODI's @Transactional not always being applied correctly. It seems to be completely ignored in some situations. I've reproduced this problem with Matthias' Modern-EE-JSF2.0 example application. I did just two modifications: 1. Weld doesn't support to inject the EntityManager via @PersistenceContext. So I created a class named EntityManagerProducer to create request scoped EntityManager instances. Then I replaced @PersistenceContext in the DAO with @Inject. This works fine with OpenWebBeans. 2. Then I removed OpenWebBeans and added Weld 1.0.1 to the dependencies. After that @Transactional immediately stopped working. It seems like the TransactionalInterceptor doesn't get invoked at all. No transactions are started and changes to the database aren't persisted any more. You can get the example application here: https://github.com/chkal/modern-ee-app20 Here are the modifications I made to the application: https://github.com/chkal/modern-ee-app20/commits/master Does anyone have an idea what is causing this? I'm not really sure if it is a CODI or a Weld issue. Thanks Christian -- Christian Kaltepoth Blog: http://chkal.blogspot.com/ Twitter: http://twitter.com/chkal
Re: MyFaces CODI and Weld 1.0.1
Hi Mark, thank you very much for your response. I've tried your suggestion and it worked great. I didn't knew about the BDA part in the spec and assumed that CODI's beans.xml would globally enable the interceptor. You are right! This BDA stuff is crap! :-) @Matthias: Nice workaround! ;) Thanks Christian 2011/3/9 Mark Struberg strub...@yahoo.de: Hi Christian! The major difference between Weld and OpenWebBeans in the interceptor area is that Weld strictly follows the Bean Definition Archive (BDA) part of the spec. This got added pretty late (in the last few weeks before the spec went final and imo is complete crap [1] ;) In Weld you have to add the interceptors section to ALL jars as well as to the WAR you like to use the interceptor in. Whereas in OWB it is enough to just have it enabled in 1 of the beans.xml files. So please try adding those section to all your beans.xml files and plz report back if that worked out.

Re: commandbutton does not call the backend bean
Seems like the validation failed for some reason. Did you add a h:messages to the page? You could also try to skip the model update (and valdiation) by setting the immediate attribute of the button to true. Christian 2010/9/28, Xiaobo Yang xiaobo.y...@gmail.com: Hi all, I'm using MyFaces 1.1.5 and Tomahawk 1.1.6 in an application and got a problem with a button. When I clicked the button, it did not call the backend bean but stayed in the same page. I noticed the lines below in the log file. org.apache.myfaces.lifecycle.LifecycleImpl - exiting from lifecycle.execute in PROCESS_VALIDATIONS(3) because getRenderResponse is true from one of the after listeners org.apache.myfaces.lifecycle.LifecycleImpl - entering RENDER_RESPONSE(6) in org.apache.myfaces.lifecycle.LifecycleImpl Could anybody explain what are the possible reasons to cause PROCESS_VALIDATIONS to stop?

Re: Issues installing Tomahawk
Are there any more information you could give us regarding this problem? Are there any exceptions that are thrown? error 503 doesn't provide much information for isolating the problem.

I'm using Netbeans 6.5, JSF 1.2 (Sun implementation) and Glassfish V2. I've followed the Setup Guide : - Add the tomahawk.jar library to the WEB-INF/lib directory - Configure the filtrer in web.xml - Add the the taglib to my pages when I use Tomahawk components But when I browse any page of my application (even those which don't use Tomahawk components), it gives me a error 503. Does anybody have any hint about this ? Thanks in advance, Steve Colombié. -- Christian Kaltepoth Blog: http://chkal.blogspot.com/ Twitter: http://twitter.com/chkal
Re: t:datatable, select a row and go to another page
On Tuesday 11 November 2008 03:25:57 tong123123 wrote: there is a t:datatable for storing the header table information, when user select a row, display a new page for the detail information of this select item, how to do this in JSF? I think I need to use t:datatable, with a field outputLink, so user can select the link in a row (master table) and then go to the detail table in another page, but the problem is how to know which row (or a key) user has pressed in the t:datatable in the detail page? is there any method to carry the user pressed value in the outputLink? Take a look at the MyFaces Wiki: http://wiki.apache.org/myfaces/ExecutingMethodsFromLinkButtonParameters This wiki page describes common patterns to solve the From List to Detail problem.. Christian
Re: Table rows without table
On Sunday 10 August 2008 21:22:05 Markus Mehrwald wrote: Hello, actually this is not really a MyFaces problem but hopefully someone can help me although. I have got a panel grid with two columns and a few rows. In this panel grid I want to have something like a data table or a data list but not as separate table in a column of the panel grid but only the rows i. e. without a own table tag. I tried to implement my own iterator which writes only tr and td tags without the table tags because I have already table tags from the panel grid. Unfortunately the panel grid always creates table tags around my iterator. Hopefully a small illustration will be helpfully for understanding what I want: Thank you for any kind of help! There are several ways to achieve this: * Use Tomahawks extended datatable with embedded=true. This prevents rendering of HTML table tags and just renders simple rows. See: http://myfaces.apache.org/tomahawk/tlddoc/t/dataTable.html * Use Tomahawks dataList component with layout=simple. This will simply render all children for each row, so you will have to render the tr and td tags yourself. See: http://myfaces.apache.org/tomahawk/tlddoc/t/dataList.html * If you are using facelets, you could also use ui:repeat See: https://facelets.dev.java.net/nonav/docs/dev/docbook.html#template-repeat Kind regards Christian

I found the context parameter 'org.apache.myfaces.EXPRESSION_FACTORY'. But to my surprise this parameter is only evaluated in a JSP 2.0 environment.

When I change from t to h and refresh the page, the control is rendered. Has anyone encountered a similar problem? Perhaps the taglib.xml file for Tomahawk is missing. In this case Facelets will ignore your t tags and render them directly to the output page. If this is the case, take a look here: http://code.google.com/p/tomahawk-facelets/ Kind regards Christian

Re: Possible bug in t:inputHidden tag/component?
Hi Eivind, Suddenly all my commandLinks and commandButtons didn't work anymore, I could press them and the form would submit (causing a reload of the page), but no actions would be fired, and the updateActionListeners stopped working as well. Did you use the h:messages/ tag in your page to display potential validation errors? Perhaps some validation error occurred that is not displayed. This would cause your action method and the listeners to be ignored because of the failure in the validation phase.
