[JBoss Seam] - different behaviour when clicking on a button or using enter
by baz
Hello,
we experience this problem:
Clicking on a button behaves different than pressing the button via return/enter key.
Scenario:
Displaying a form (long-running-conversation active)
Inside this form the user can activate a new page which starts a nested conversation.
| <ui:composition xmlns=[...]
| <ui:define name="body">
| <h:form>
| [...]
| <h:commandButton action="#{tgw.save}" value="save"></h:commandButton>
| </h:form>
| </ui:define>
| </ui:composition>
|
The save action is annotated with @End and it performs a endAndRedirect:
@End()
| public void save(){
| [...] Events.instance().raiseEvent("CALCYIELD",plot);
| Conversation.instance().endAndRedirect();
| }
|
When clicking on the button, the user is redirected to the enclosing form and the nested conversation has ended.
But when the user presses the return/enter key inside the form a redirection to the enclosing form happend but the nested conversation has not ended.
What is going on here?
This is happening inside a seam-gen generated project (with Seam2.0.0Beta1)
I've just reassured that the save action is really called when pressing enter/return
Another related question (which has little relation to seam but to JSF in general. Perhaps someone has a hint)
I have to deal with a couple of peoples who are used to press enter when they enter a numeric value in a field.
I do not want to submit the form in this case. The only way to catch this scenario for me, is to place a default button at the top of the form which does nothing.
Are there better ways?
Ciao,
Carsten

[JCA/JBoss] - database failover for ejb application (persistance.xml probl
by grdzeli_kaci
hi all,
i tried to use database failover by ha-xa-datasource.
my database configuration file looks like :
1.oracle-ha-xa-ds.xml
| <datasources>
| <ha-xa-datasource>
| <jndi-name>XAOracleDS</jndi-name>
| <track-connection-by-tx/>
| <isSameRM-override-value>false</isSameRM-override-value>
| <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
| <!-- list of connection URLs -->
| <xa-datasource-property name="URL">jdbc:oracle:thin:@192.168.9.135:1521:DEVSTR|jdbc:oracle:thin:@192.9.200.222:1521:DEVSTR</xa-da
| <xa-datasource-property name="User">USER_MANAGER</xa-datasource-property>
| <xa-datasource-property name="Password">USER_MANAGER</xa-datasource-property>
| <url-property>URL</url-property>
| <url-delimeter>|</url-delimeter>
| <valid-connection-checker-class-name>tempPackage.OracleValidConnectionChecker</valid-connection-checker-class-name>
| <exception-sorter-class-name>tempPackage.OracleExceptionSorter</exception-sorter-class-name>
| </ha-xa-datasource>
| </datasources>
|
bu ti can't use this configuration into my ejb application,
is there any doc or example how to config my persistance.xml in this case ????
my persistance.xml looks like :
2.persistance.xml
| <?xml version="1.0" encoding="ISO-8859-1" ?>
| <persistence xmlns="http://java.sun.com/xml/ns/persistence"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
| version="1.0">
| <persistence-unit name="Test">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <non-jta-data-source>java:/XAOracleDS</non-jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto" value="validate"/>
| <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider"/>
| <property name="hibernate.default_schema" value="USER_MANAGER"/>
| </properties>
| </persistence-unit>
| </persistence>
|
i tried to use jta-data-source instead of non-jta-data-source but i got the errors :
1.non-jta-datasource:
