[JBoss Seam] - Re: faces-config.xml is missing in booking example?
by asookazian
Not sure if this facestrace-0.8.1.jar is compatible with Eclipse 3.2.2 and JBoss 4.2.1.GA and Seam 2.0.0.CR2 or not.... it states in the instructions to place the <ft:trace/> tag at the end of your JSF file.
Trying to use facestrace with main.seam, when I navigate to main.seam, I get the following:

| <h1>State management in Seam</h1>
| <p>
| State in Seam is <em>contextual</em>. When you click "Find Hotels", the application
| retrieves a list of hotels from the database and caches it in the session context. When you
| navigate to one of the hotel records by clicking the "View Hotel" link, a <em>conversation</em>
| begins. The conversation is attached to a particular tab, in a particular browser window. You can
| navigate to multiple hotels using "open in new tab" or "open in new window" in your web browser.
| Each window will execute in the context of a different conversation. The application keeps state
| associated with your hotel booking in the conversation context, which ensures that the concurrent
| conversations do not interfere with each other.

[JBoss Seam] - Binding Component to Backing Bean Property
by mikeeprice
I tried to bind a component to a backing bean property
<h:form>
<h:panelGrid id="panelGrid_01" binding="#{conceptManager.letterPanelGrid}"/>
</h:form>
and ran into this problem.
"You can't bind to a CONVERSATION scoped backing component because the conversation context is not available in the RESTORE VIEW phase."
So I changed the scope to Session
@Stateful
@Name("conceptManager")
@Scope(ScopeType.SESSION)
public class ConceptManagerAction implements ConceptManager, Serializable{
and still had the same problem.
java.lang.IllegalStateException: No conversation context active org.jboss.seam.ScopeType.getContext(ScopeType.java:126) org.jboss.seam.Component.outjectAttribute(Component.java:1665)
...
com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:93) com.sun.faces.lifecycle.RestoreViewPhase.doPerComponentActions(RestoreViewPhase.java:244)
Is it possible that I could write a PhaseListener that runs before RestoreView and makes the necessary context avaiable so that resolving the binding expression during RestoreView will work? If not then would the closest alternative be creating a custom component that will create the kind of PanelGrid I would like to have?
Thanks Mike Price

[JBoss Seam] - faces-config.xml is missing in booking example?
by asookazian
Seam 2.0.0.CR2
I did a search and several of the other example projects have a faces-config.xml in the resources folder.
Why is this? the booking example in 1.2.1.GA had a faces-config.xml.
Also, I want to start using facestrace to trace JSF lifecycle info:
http://facestrace.sourceforge.net/index.html
anybody used this with the Seam booking example? I will need to add a faces-config.xml as follows, but it seems to be missing from the instructions to do this:
| <faces-config>
| <managed-bean>
| <managed-bean-name>traceData</managed-bean-name>
| <managed-bean-class>net.sf.facestrace.TraceData</managed-bean-class>
| <managed-bean-scope>request</managed-bean-scope>
| </managed-bean>
|
| <lifecycle>
| <phase-listener>net.sf.facestrace.phase.listener.RestoreViewPhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.ApplyRequestValuesPhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.ProcessValidationsPhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.UpdateModelValuesPhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.InvokeApplicationPhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.RenderResponsePhaseListener</phase-listener>
| <phase-listener>net.sf.facestrace.phase.listener.TraceResourcePhaseListener</phase-listener>
| </lifecycle>
|
| <component>
| <component-type>net.sf.facestrace.component.Trace</component-type>
| <component-class>net.sf.facestrace.component.Trace</component-class>
| </component>
|
| </faces-config>
