To avbentem: thank you. I was marking which parts were finished (DONE). But now all parts are at least partly implemented, so I have now page with issues (http://software.softeu.cz/seam/issues.html).

Oh, here is the TSS thread:

http://www.theserverside.com/news/thread.tss?thread_id=44438

man, you guys are cranking. I'm glad I got on board early.

I only have 10Gb limit a month on my ISP Plan. ;)

These releases are coming thick and fast which is GREAT :).

MyEclipse download was getting out of control at over 150MB (which now includes the complete Stack including Eclipse and MyEclipse in an ALL-In-ONE!)... and they now use some UBER compression tool to squeeze it.

I wonder how much the 66MB could be squeezed into!

pages.xml ending conversation is broken with 1.2, only works with plain navigation.xml!

Hi,

don't know if it has been corrected or not. We just detected a problem in org.jboss.seam.ui.UISelectItems. There's a

private static final String NO_SELECTION_VALUE = null;

defined which should be replaced by

import static org.jboss.seam.ui.NoSelectionConverter.NO_SELECTION_VALUE;

Because:
SelectItems class always uses 'null' as value of NullableSelectItem. Therefore during conversion this is not recognized by the NoSelectionConverter.

Without this change the s:selectItems will not work with noSelectionLabel set.

No.

Render phase:
1) UISelectItems adds the NullableSelectItem to the list
2) NoSelectionConverter runs getAsString, the NullableSelectItem has a value null so NoSelectionConverter.NO_SELECTION_VALUE is returned

Submit phase:
1) NoSelectionConverter runs getAsObject, the value is NoSelectionConverter.NO_SELECTION_VALUE, so null is returned
2) Validators are run, if required=true, then, as the value is null, validation will fail
3) The model is updated with a null value.

I can't see a problem - the UI example has noSelectionLabel on both components with required=true and not and the behaviour I describe happens.

What problem are you seeing?

Hi,

thanks for your answer. Here's some code:

Page:

<ice:selectOneMenu id="projectselection" value="#{projectControllingActions.selectedProject}"
 valueChangeListener="#{projectControllingActions.projectSelectionChanged}"
 partialSubmit="true" required="true">

 <s:selectItems value="#{projectControllingActions.projects}" var="project"
 label="#{project.name}" noSelectionLabel="#{apc_messages.please_select}"/>
 <s:convertEntity />

</ice:selectOneMenu>

<ice:selectOneMenu id="taskselection" value="#{projectControllingActions.selectedTask}">
 <s:selectItems value="#{projectControllingActions.tasks}" var="task"
 label="#{task.description}" noSelectionLabel="#{apc_messages.please_select}"/>
 <s:convertEntity />
</ice:selectOneMenu>

Quite possibly, I've never personally tested this with icefaces. The easiest way to check is just to swap in a normal h:selectOneMenu and see whether it works as expected. Perhaps ask over at icesfaces?

We tried this with normal h:selectOneMenus. But it's the same exception ...

So we thought the bug has to be in Seam. And with the mentioned workaround this app works as it should.

Hmm. I'm wondering which framework delivers the converters, since the excpetion tells that a conversion from null to Integer failed.

Post the exception :), see if it pins things down...

If you submit a testcase to JIRA (needs to be simple and have just enough code to demonstrate the problem) I'll take a look at it. You could probably take the ui example and manipulate it...

As of ICEfaces 1.6.0 DR#3, substantial progress has been made with Seam/ICEfaces integration. In general, it is enough to simply add the ICEfaces .jar files to turn your Seam application into an Ajax application. Please download the latest ICEfaces release here:

http://icefaces.org/main/downloads/os-downloads.iface

Of particular interest are Ajax Push and seam-gen. ICEfaces Ajax Push is now working with Seam applications (this allows you to update the browser page under application control; no interaction from the user is required). To generate an ICEfaces application with seam-gen, please download the recently added ICEfaces seam-gen bundle

http://icefaces.org/main/downloads/project-downloads.iface

and unzip it at the root of your Seam 1.2.1 installation. You will then be able to generate ICEfaces Seam applications from within the icefaces-seam-gen directory. Over time we will be enhancing these templates to take full advantage of ICEfaces, allowing you to automatically generate a full CRUD application with a single-page Ajax user interface.

Can ICEfaces 1.6 and Richfaces be used in the same application?
