[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1516) Issuing another request while waiting for AJAX request to return causes concurrent conversation exception

by Robb Greathouse (JIRA)

Issuing another request while waiting for AJAX request to return causes concurrent conversation exception --------------------------------------------------------------------------------------------------------- Key: JBSEAM-1516 URL: http://jira.jboss.com/jira/browse/JBSEAM-1516 Project: JBoss Seam Issue Type: Bug Components: Async Affects Versions: 1.2.1.GA Environment: RichFaces, AJAX and Seam 1.2.1 Reporter: Robb Greathouse Priority: Minor When the user kicks off an AJAX request and then clicks on a link before it responds we get a concurrent conversation exception. Shouldn't a request that would cause this error be held until the request either times out or is completed and then passed through? Thinking that the filter in tomcat that gets the conversation could also prevent consurrency crashes. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1661) Use more templating in seam-gen

by Matt Drees (JIRA)

Use more templating in seam-gen ------------------------------- Key: JBSEAM-1661 URL: http://jira.jboss.com/jira/browse/JBSEAM-1661 Project: JBoss Seam Issue Type: Feature Request Affects Versions: 2.0.0.BETA1 Reporter: Matt Drees Priority: Minor Seam-gen'ed apps tend to look very copy-pasted, which makes it difficult to tweak things once created. It'd be nice if it used more templating and/or source tags (maybe going as far as using Rick Hightower's <a:field fieldName="title" entity="#{CDManagerBean.cd}" /> tag (see http://www.ibm.com/developerworks/java/library/j-facelets/index.html and http://www.ibm.com/developerworks/java/library/j-facelets2.html)). Also, I think it would be good for people new to JSF to see good patterns in an example app. The downside is it's more complex, but I think it's worth it. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2380) Icefaces jars need exclusions

by Pete Muir (JIRA)

Icefaces jars need exclusions ----------------------------- Key: JBSEAM-2380 URL: http://jira.jboss.com/jira/browse/JBSEAM-2380 Project: JBoss Seam Issue Type: Task Affects Versions: 2.0.1.CR1 Reporter: Pete Muir Priority: Trivial There is a new icefaces jar that will be in 1.7.0 release onwards. It's the asynchronous hub server for server-push in a separate package and will affect the builds that we already have with Seam in that it should not be included in the application packages unless it is configured properly. Thus, the build scripts should have an <excluded name="icefaces-ahs.jar"/> for this reason. (I hope this makes sense!!) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2221) Introduce way to retrieve proxy object of a Seam JavaBean Component

by Wolfgang Schwendt (JIRA)

Introduce way to retrieve proxy object of a Seam JavaBean Component ------------------------------------------------------------------- Key: JBSEAM-2221 URL: http://jira.jboss.com/jira/browse/JBSEAM-2221 Project: JBoss Seam Issue Type: Feature Request Reporter: Wolfgang Schwendt The EJB programming model requires that a Session Bean never passes a "this"-pointer to other client objects. Instead, javax.ejb.SessionContext provides a method getBusinessObject(). If a SessionBean wants to pass a reference pointing to itself to other clients, it first has to retrieve its own EJB object reference by calling SessionContext.getBusinessObject() which it then can pass to other beans. This reference returned by javax.ejb.SessionContext.getBusinessObject() is the equivalent to Java's this pointer. With respect to Seam's interceptor framework, such a feature is missing as far as normal JavaBean components are concerned. It leads to subtle programming errors: Consider the implementation of org.jboss.seam.framework.Query. getDataModel(): /** * Wrap the result set in a JSF {@link DataModel} * * Delegates to {@link DataModels#getDataModel(Query)} * */ @Transactional public DataModel getDataModel() { if (dataModel==null) { dataModel = DataModels.instance().getDataModel(this); } return dataModel; } This method method passes a "this"-reference to the org.jboss.seam.faces.dataModels Seam-component. But this can lead to a behavior not expected by the programmer. If the (Entity)Query-component gets instantiated as a conversation-scoped component, Seam wraps the ManagedEntityIdentityInterceptor around this Query component. After each method invocation intercepted by the ManagedEntityIdentityInterceptor, the ManagedEntityIdentityInterceptor saves wrappers for all contained Entity references in the conversation context and sets the corresponding reference fields in the Query component to null. Now, consider again above implementation of Query.getDataModel(). Because a "this" pointer is passed to the dataModels-component, any calls conducted by the datamodel-component via this reference won't (!) be routed through the ManagedEntityIdentity interceptor. Hence, when the datamodel-component calls the Query-component via the Java-this pointer it received previously, the ManagedEntityIdentity won't be invoked and in turn the Entity reference fields in the Query-component won't be restored. This leads to a bug as described in JBSEAM-1814. In order to fix that bug, we would have to change the implementation of Query. getDataModel(). Rather than passing the Java-this pointer to the dataModels component, the correct implementation would be as follows. The Query component would first have to retrieve a reference to its own proxy object, which it then could pass to the dataModels component. Summary: For JavaBean Seam components we need a feature similar to SessionContext.getBusinessObject(), to enable a JavaBean Seam component to pass a proxy reference to itself to other Seam components instead of passing directly the Java-this pointer. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2261) Default s:link propagation attribute value.

by Richard Teviotdale (JIRA)

Default s:link propagation attribute value. ------------------------------------------- Key: JBSEAM-2261 URL: http://jira.jboss.com/jira/browse/JBSEAM-2261 Project: JBoss Seam Issue Type: Feature Request Affects Versions: 2.0.0.GA Reporter: Richard Teviotdale The propagation attribute of s:link has possible values of begin, join, nest, none or end. When the attribute is not specified the tag propagates the active conversations by default. Please add a value that specifies the default behavior - perhaps propagation="propagate". Please see forum posting for more information. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2202) Make all basic JSF Converters and Validators into Seam Components

by Dan Hinojosa (JIRA)

Make all basic JSF Converters and Validators into Seam Components ----------------------------------------------------------------- Key: JBSEAM-2202 URL: http://jira.jboss.com/jira/browse/JBSEAM-2202 Project: JBoss Seam Issue Type: Feature Request Reporter: Dan Hinojosa I was thinking though through this problem that all basic converters should be accessible as a seam components. The impetus for this idea came from a problem I was having of displaying prices in a drop down list, see forum link for details. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-2201) include <generic-type> in components.xml

by Dan Hinojosa (JIRA)

include <generic-type> in components.xml ---------------------------------------- Key: JBSEAM-2201 URL: http://jira.jboss.com/jira/browse/JBSEAM-2201 Project: JBoss Seam Issue Type: Feature Request Reporter: Dan Hinojosa I would like a generic-type allowed in components.xml so that we can have genericized beans. For example <component name="productManagerBean" scope="SESSION" class="com.xyzcorp.session.SimplePersistenceManagementBean" generic-type="com.xyzcorp.entity.Product" /> This would be great so we could do some kick ass stuff like this @Stateful public class SimplePersistenceManagementBean<E> { private E entity; @PersistenceContext(....) private EntityManager em; public void setEntity(E entity) { this.entity = entity; } public void create() { em.persist(e); } public void update() { em.merge(e); } ....... } Now, ain't that sexy? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
