[jboss-user] [JBoss Seam] - Re: Nested Conversations (tricky interceptor)
anonymous wrote : Entities references in conversational components are moved from the object to the conversation at the end of a request and are repopulated in the object at the beginning of the next request. As I understand not a request, but method invocation. I can tell you where is the problem. Suppose that we have component AA in parent conversation with a field reference bb to an another component Q. At some point this reference is moved to conversation context with the name AA.bb. Then we start nested conversation. We can still access field bb in the nested conversation, because in the time of invocation it gets reference from the parent conversation and put it inside the component. Then we change the reference of the field. And at the end of an invocation seam moves the reference to the conversation context (nested) Then we end the nested conversation. And try to access field bb in the parent conversation. Seam restores a reference from context (parent). And we get the old value.

[jboss-user] [JBoss Seam] - Nested Conversations (tricky interceptor)
From the first look my question seems to be trivial, but it is not. How to return some information form the nested conversation to the parent conversation? In docs there is line:anonymous wrote : A nested conversation has its own conversation context, and also has read-only access to the context of the outer conversation. (It can read the outer conversation's context variables, but not write to them.) I always thought this as that I can't change the Map of the parent context variables, but I can change the state of any object in parent conversation context. And everything works as expected till Seam 2.x. After Seam2 there was strange behavior all around in my application. Some fields of some objects unexpectedly becomes nulls or old values. After examining this situation I have found this interceptor ManagedEntityIdentityInterceptor. With this interceptor I have problems with changing state of objects in the parent conversation context. Is it intended behavior or a bug? If it is intended then how to transmit parameters to the parent conversation in Seam 2.x?

[jboss-user] [JBoss Seam] - Re: Passing data between nested conversations
From the nested conversation you have access to the parent conversation scope.
You can't add or remove from the parent scope, but you can get a reference to
an any object and you can change the state of this object.
Next thing you can do. You can pass parameters when you start nested
conversation.
For instance, to choose link object I use nested conversation (old one, because
I use 1.2.1 version)
In this way I start nested conversation
a4j:commandLink value=#{messages['com.colvir.common.choose']}
action=#{refer.begin} propagation=nest
| a4j:actionparam name=ref value=#{refName}
assignTo=#{refer.refName}/
| a4j:actionparam name=caption value=#{caption}
assignTo=#{refer.caption}/
| a4j:actionparam name=binding value=#{binding}
assignTo=#{refer.binding}/
| a4j:actionparam name=viewid value=#{viewid}
assignTo=#{refer.viewid}/
| /a4j:commandLink
|
In this way I return from nested to parent
public String select() {
| if (binding==null){
| throw new RuntimeException(Binding in reference can't be null);
| }
| Query r = getRef();
| if ( r==null ){
| throw new RuntimeException(Reference query can't be null);
| }
| Object o = r.getDataModel().getRowData();
|
| // End conversation and redirect to parent
| Conversation.instance().endAndRedirect(true);
| // Returning selected value
|
Expressions.instance().createValueBinding(#{+binding+}).setValue(o);
| return null;
| }
|
| public String cancel() {
| Conversation.instance().endAndRedirect(true);
| return null;
| }
|
Actually, with composite pageflows everything has to be much simpler.
Denis.

[jboss-user] [JBoss Seam] - Re: How bad is unused conversations?
Yes it is very important question. now we have: begin - marks current not long running conversation to be long running. end - marks current long running conversation to be not long running. join - join existing conversation (now it fails if there is no long running conversation, as I remember. Gavin promised to fix it ;-) nest - begins nested conversation none - leave the current long running conversation But what if I want to start a new conversation no matter where I am now? Either I am in long running conversation or in not long running. Like in this situation with menu bar. When I click menu item I want to start clean new long running conversation. In more strict words, to leave current conversation, to start new one (before render) and to mark a new one as long running. (I am not sure is it possible now to leave one and start another new conversation inside one request?)

And I think you do not need nested conversations for this scenario. Do it in
one conversation. Just throw away lower level selections when you make
selection on some level.

or
//@End

Second question @Out @In works with contexts. @Out private String hotel; The @Out annotation declares that an attribute value is outjected to a context variable after method invocations. In this case, the context variable named hotel will be set to the value of the hotel instance variable after every action listener invocation completes. (C)Seam Reference. The key point for understanding, that injection and outjection occurs on each invocation of an any method of this bean, that was made as action listener invocation. If you just call method from java code there will be no in/outjection. And also be aware with what contexts you are working.

Is there a consistent way to control FlushMode? I have tried this, but it does not do what i expected. persistence.xml ... property name=hibernate.transaction.flush_before_completion value=false/ ... Yes. There is the annotation attribute @Begin(flushMode=MANUAL), but not always you can use an annotations. For instance, if you start a conversation through s:link there is no such option. It is this code that partially works for me: PersistenceContexts.instance().changeFlushMode(FlushModeType.MANUAL); If i call this code somewhere in my home object it works.

[jboss-user] [JBoss Seam] - Testing Pageflow with SeamTest
Is it possible to test Pageflow conversations with the mock environment ? Is there a special technique or a sample how to do this? P.S. I have found that Seam's testing environment is an extremely useful and elegant. It increases productivity in many times. Now i stuck in testing pageflows, but i already can't live without testing ;-) Thanks.

[jboss-user] [JBoss Seam] - Re: MockApplication in SeamTest not easily overridable
Seam uses facelets to work with JSF. There is no JSP at all. Facelets now controls creation and manipulation of JSF component tree. And as I understand you cannot control the JSF component tree the way that was suggested in the article, if you work with facelets. But do not worry. Facelets has a very nice template and dynamic capabilities. Just look at facelets docs you will love it.

[jboss-user] [JBoss Seam] - Re: What do you guys think of this idea?
I think it is good idea to hold the meta information in the file with view. Because there is no need in a separation. All information in page.xml now concerns a particular views. It is matter of grouping by type or by subject. In this case I should prefer grouping by subject. Yes, I usually also like to keep different things in different places, but let us be wise with this.

[jboss-user] [JBoss Seam] - hibernate-ALL.jar
Hello Gavin. Is it principle to keep Hibernate dependences in one file? Why not to split it in standard Hibernate jars with versions? There is several inconveniences with Hibernate-ALL 1. In debugging, when you want to link sources to hibernate, you have to merge sources from three hibernate projects. (Also there is no information about versions) 2. Integration with Maven2. (... May be someone can add something ...) Would you at least give information about versions of Hibernate jars. (in 1.0.1.GA and current CVS) With respect, Denis Karpov.

[jboss-user] [JBoss Seam] - Re: one method ending conversation or not
There are two approaches.
First, if you use Page Flows, then you can make decision node where you decide
what is next.
.
| page name=yourPage view-id=/qqq/eee.xhtml
| redirect/
| transition name= to=check
| action expression=#{yourController.doSomething}/
| /transition
| /page
| decision name=check expression=#{yourController.conditionOfEnd}
| transition name=true to=end
| action expression=#{yourController.done}/
| /transition
| transition name=false to=yourPage/
| /decision
| .
Second, you can end your conversation explicitly from the code.
Conversation.instance().end();

As I see, it has to be like this:
public class AppUser implements Serializable {
| ...
|private FullName name;
|public FullName getName()
|{
| return name;
|}
|public void setName(FullName name)
|{
| this.name = name;
|}
| ...
|
then your code should work.

[jboss-user] [JBoss Seam] - Problem with conversation stack(nested Pageflows blocker)
public class Pageflow implements Serializable {
| ...
|public static Pageflow instance()
|{
| ...
| return (Pageflow) Component.getInstance(Pageflow.class,
ScopeType.CONVERSATION, true);
|}
| ...
|
public class Component {
| ...
|public static Object getInstance(String name, ScopeType scope, boolean
create)
|{
| Object result = scope.getContext().get(name);
| result = getInstance(name, create, result);
| return result;
|}
| ...
|
public class ServerConversationContext implements Context {
| ...
|public Object get(String name) {
| ...
| LinkedListString stack = getIdStack();
| ...
| for ( String id: stack )
| {
| result = session.getAttribute( getKey(name, id) );
| if (result!=null) return result;
| }
| return null;
| ...
| }
|
Using this pattern we can have only one such Component (in this case Pageflow)
per Conversation stack. When we ask for a new instance we will get an old one
from some parent Conversation.
This is the main thing that prevents using nested Pageflows.
May be it is reasonable to add another option in Component.getInstance() to
lookup only in one current Conversation.

Do not call fillMaps(); in a getter. I think it will solve all of your problems. Good place to call it in the factory method or like that. Then, I think you misunderstand this line model.put((Empty),-1); // Add EMPTY element if needed It is EMPTY element. It is needed to choose null value. If you do not need null values just remove this line.

[jboss-user] [JBoss Seam] - Re: JSTL tags ignored
It is hot topic on faselets forum. Specially c:if? case. Your mistake is you are trying to use build-time tag as render-time. For instance, instead of c:if almost always you should use rendered attribute. . Why doesn't my c:if / ui:repeat / ui:include work properly? You're probably using a bad combination of build-time and render-time tags. For example, c:if is a build-time tag, so any EL expressions are only evaluated once (when the tree is built), even if you put it inside a ui:repeat or h:dataTable. Conversly, since ui:repeat is a 'render-time tag' (i.e. a UIComponent), you can't use it to iterate over build-time tags such as f:selectItem. Build-time (facelet) tags: · all JSTL tags (e.g. c:if, c:forEach, c:choose) · all ui tags except ui:repeat (e.g. ui:include, ui:decorate, ui:composition) · all core faces tags except f:verbatim (e.g. f:validator, f:convertNumber, f:selectItem) Render-time tags (UIComponents): · all UIComponent tags (e.g. ui:repeat, h:inputText, t:saveState) http://wiki.java.net/bin/view/Projects/FaceletsFAQ#Why_doesn_t_my_c_if_ui_repeat_ui View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3973581#3973581 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3973581 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss Seam] - Re: Multiple roles and accessing the DataModel
In this case you can use:

| yourBean.getYourModel.getRowIndex();
|
But you should not create DataModel each time in a getter.
I use it something like this:
private DataModel dm = null;
|
| public DataModel getDetails() {
| if (dm==null){
| dm = new ListDataModel();
| }
| return dm;
| }
|
| private void syncDetails() {
| Client o = getObject();
| if (o!=null){
| getDetails().setWrappedData(o.getDocuments());
| }
| }
|
| private IdentityCard getSelectedDocument() {
| return (IdentityCard)getDetails().getRowData();
| }
|
Frankly, I do not like
@DataModel
@DataModelSelection
@DataModelSelectionIndex

You should use it like this #{list}, because when you use @DataModel Seam
outjected wrapper into the current context with name of the property (list in
your case)
Another way you should wrap it by yourself, only then you can use it the way
#{YourBean.YourModel}

[jboss-user] [JBoss Seam] - Re: Problem: Custom validate methods in EJBs crash
1. For simple validation (just value) we can still use JSF validation. 2. For complex validation I use drools (jBoss Rules). It nicely integrated with Seam Page Flow (see seam samples). You can express your validation in rule set. IMHO it looks like quite elegantly. You can define as complex rules as you want. And validation logic is separated. And most important, it works steadily. I have not experienced any problems yet. Denis.
