Actions not hitting methods (always)
Hi guys,
I have just been getting into Seam and am pretty new. I am sorry in advance if my problem just comes from me not looking hard enough, but I think I have looked pretty hard, at least for what I know.
So, I have my Setup province page...

And my stateBean class looks like...
import java.util.List;
import javax.ejb.Remove;
import javax.ejb.Stateful;
import org.hibernate.Hibernate;
import org.jboss.seam.annotations.Begin;
import org.jboss.seam.annotations.Conversational;

@Stateful
@Name("stateBean")

@SuppressWarnings("all")
public class StateBean extends BaseBean implements State {
@DataModelSelection("stateList")
@Out(required = false)
@In(required = false)
private SiState state;

@DataModel

@In(required = false)
private SiStateTax stateTax;
@In(required = false)

@In(required = false)
String provinceCountry;
@Destroy
@Remove
public void destroy() {
state = null;
stateList = null;
department = null;
}
/**

*/
@Factory("stateList")
@Begin(join = true, flushMode = FlushModeType.MANUAL)
public void setup() {
String sql = "FROM SiState where siCountry = 'USA' order by siStateCode";
stateList = entityManager.createQuery(sql).getResultList();
for (SiState state : stateList) {
Hibernate.initialize(state.getTaxItems());
}
state = user.getCurrentDepartment().getState();
}
/**
* Method to return a list of provinces names based on the country passed in
*/
@Factory("provinceList")
@Begin(flushMode = FlushModeType.MANUAL, join = true)
public void getStatesByCountry() {
if(provinceCountry == null)
provinceCountry = "CAN";
// query to get all states that have a country that matches the
// province.getCountry property
String hql = "FROM SiState " +
"WHERE siCountry = '" + provinceCountry + "'";
// Run the query and put the result in an SiState list to cast into
// provinces later
provinceList = entityManager.createQuery(hql).getResultList();
}
@Begin(flushMode = FlushModeType.MANUAL, join = true)
public void selectState() {
}
/**
* Method to delete a Tax from this state
*/
@Begin(flushMode = FlushModeType.MANUAL, join = true)
public void deleteTax() {
// Remove the taxItem from the state
state.getTaxItems().remove(stateTax);
// Remove the state Tax from the DB
entityManager.remove(stateTax);
entityManager.flush();
}
/**
* Method to add a Tax to this state
*/
@Begin(flushMode = FlushModeType.MANUAL, join = true)
public void addTax() {
// Add the new tax to the state's list of taxes
state.getTaxItems().add(stateTax);
// Set the stateTax state, to the current state
stateTax.setState(state);
// Save the stateTax
entityManager.merge(stateTax);
entityManager.flush();
}
}
The problem is, when I load information in the span: provinceTaxRates, and the RemoveTax button that is loaded with it is clicked, nothing happens (aside from the page being loaded.)
After I hit the Add Tax button and stateBean.addTax() is called, my remove tax button begins to work.
Is the reason obvious?
