[JBoss Seam] - EntityHome.persist fails with @GeneratedValue

by dougorr

I am using a simple Seam-Gen generated application. I want to change the @Id field in the model class to be auto-generated. I changed the annotation to read as follows: @Id @GeneratedValue(strategy=GenerationType.AUTO) When I run the application the EntityHome.persist throws an exception. Here is the stack trace: | avax.servlet.ServletException: Error calling action method of component with id optionalParent:save | at javax.faces.webapp.FacesServlet.service(FacesServlet.java:152) | at

[JBoss Seam] - Re: JSF way to conditionally add attributes

by mgrouch

something like <s:attribute name="#{expr}" value="#{expr4value}" rendered="#{condition}"/> is needed badly.

[JBoss Seam] - Re: JSF way to conditionally add attributes

by mgrouch

I've tried using f:attribute tag inside the component I needed to add attribute to. It didn't work. Is there JSF solution (without coding in Java and doing binding)? This is VERY common problem and there should be something to do it in JSF page itself... Might be Seam could provide s:attribute which would actually work as people expect it to work.

[JBoss Seam] - Re: JSF way to conditionally add attributes

by ishabalov

A least you can use binding and Java API to put anything you need into attributes map. Just remember that it must be serializable.

[JBossWS] - Object Array with multiple subclasses fails

by robb.greathouse＠jboss.com

When an array of objects is passed as a parameter webservices appears to check the first member and selects the correct subclass for instantiation. However, if a subsequent member is a different subclass an error results as it attempts to marshal into the same subclass. It then complains that there is a field that is not valid in that position. Apparently, it only checks once when processing a object array that is filled with multiple subclasses. There was a similar problem in pojo cache during replication last year and they were able to fix it over night.

[JBoss jBPM] - GPD 3.1_CR issues

by jeffcwang

Hi, Using the current GPD, it seems that there is a problem sync'ing changes made to the source and the diagram image and vice versa. For example, if I add some task nodes using the diagram and then edit the XML source directly (adding swimlanes, transitions etc), some changes will be reflected to the diagram and some will not (seems random). Even worse, after doing that, adding nodes to the diagram will not update the XML. Has anyone else experienced this and is there a workaround? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074626#4074626 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4074626

If you're trying to execute an SQL (not JPA QL), just try with this: | int rowCnt= (Integer) em.createNativeQuery("SELECT count(1) FROM TableA").getSingleResult(); | HTH.

[JBoss Seam] - How to use EntityManager for SELECT COUNT(1)?

by tonylmai

First I'd like to apologize for posting a persistence question on this board. I've tried other boards but no one's home. I am desperate :-( I would like to perform a SELECT COUNT(1) FROM a table "TableA" but can't seem to get the SQL statement to work with EntityManager. The following code always return a 0 even I know the table contains hundreds of records. int rowCnt= (Integer) em.createQuery("SELECT count(1) FROM TableA").getSingleResult(); Can anyone help? I am using JBoss 4.2.1 with Seam 1.2.1. Thanks. -tony View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4074624#4074624 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4074624

[JBoss Seam] - How to use declare/use namespace locally?

by tonylmai

Hello, I am trying to use ILOG JViews Chart with Seam 1.2.1. I am running into prefix not bound to a namespace problem. anonymous wrote : XML Parsing Error: prefix not bound to a namespace | <jvcf:chartView style="width:500 px; height:300 px;"></jvcf:chartView> where jvcf is defined as xmlns:jvcf="http://www.ilog.com/jviews/tlds/jviews-chart-faces.tld" I think the URL is not valid. I found a copy of jviews-chart-faces.tld locally. Can I define the namespace to use the local copy instead? How would I go about doing that?
