[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - Problem with valueChangeListener in inputText of a DataTable
Hello,
I write a program which should show Data in a Table and the user should be able to edit
them.
The Table has to be generated dynamicaly. For simplicity I create a table with 2 cols und
2 rows (see: getColumnModel() and getTableModel() in SessionBean). When I run the
application there appears a problem.
The valueChanged - Method is just called when I change the value of one of the two fields
in the first column.
Why isnt the Method called when I change the value of a field of the second column?
My jsp-File looks as followed:
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"
%>
Vitax Web 1.0
<f:view>
<h:form id="taxForm">
<t:dataTable id="taxTable" var="row"
value="#{taxTable.tableModel}">
<t:columns value="#{taxTable.columnModel}" var="col">
<f:facet name="header">
<h:outputText value="#{col}" />
</f:facet>
<t:inputText id="in"
value="#{row[taxTable.columnModel.rowIndex]}"
valueChangeListener="#{taxTable.valueChanged}" immediate="true"
onchange="submit()">
</t:inputText>
</t:columns>
</t:dataTable>
</h:form>
</f:view>
Here is the code for the taxTable SessionBean:
public class TaxTable {
private javax.faces.model.ListDataModel tableModel;
private javax.faces.model.ListDataModel columnModel;
public SessionBean() {
}
public void valueChanged(ValueChangeEvent evt) {
System.out.println("Old Value: "+evt.getOldValue().toString());
System.out.println("New Value: "+evt.getNewValue().toString());
}
public javax.faces.model.ListDataModel getTableModel() {
if(tableModel == null) {
Object[] o1 = new Object[] {"Zeile 1", new Integer(1)};
Object[] o2 = new Object[] {"", new Integer(2)};
List<Object[]> l = new ArrayList<Object[]>();
l.add(o1);
l.add(o2);
tableModel = new ListDataModel(l);
}
return tableModel;
}
public void setTableModel(javax.faces.model.ListDataModel tableModel) {
this.tableModel = tableModel;
}
public javax.faces.model.ListDataModel getColumnModel() {
if(columnModel == null) {
String[] o1 = new String[] {"Spalte1",
"Spalte2"};
List l = new ArrayList();
l.add(o1[0]);
l.add(o1[1]);
columnModel = new ListDataModel(l);
}
return columnModel;
}
public void setColumnModel(javax.faces.model.ListDataModel columnModel) {
this.columnModel = columnModel;
}
}
I'm using myfaces1.1.4 (Tomahawk) and apache Tomcat5.5.20.
Please help me.
Thx!
