The right type not recognised in expression
-------------------------------------------
Key: TOMAHAWK-515
URL: http://issues.apache.org/jira/browse/TOMAHAWK-515
Project: MyFaces Tomahawk
Type: Bug
Versions: 1.1.5-SNAPSHOT
Environment: JBoss 4.0.4.GA
MyFaces 1.1.3
Tomahawk+Sandbox 1.1.5 snapshot
Reporter: RD
<t:dataTable id="vertragData" styleClass="standardTable"
headerClass="standardTable_Header"
footerClass="standardTable_Header"
rowClasses="standardTable_Row1,standardTable_Row2"
columnClasses="standardTable_ColumnCentered"
var="vertrag" value="#{vertragListBean.vertragList}"
preserveDataModel="true" rows="20"
sortColumn="#{vertragListBean.sort}"
sortAscending="#{vertragListBean.ascending}"
preserveSort="true">
<x:commandLink action="edit" immediate="true"
rendered="#{vertrag.status == 'A' || vertrag.status ==
'a'}">
private List<Vertrag> vertragList =new ArrayList<Vertrag>();
public List<Vertrag> getVertragList() {
doFilter();
doSort(getSort(),isAscending());
return vertragList;
}
public class Vertrag implements Serializable {
private Character status;
...
public Character getStatus() {
return status;
}
public void setStatus(Character status) {
this.status = status;
}
...
}
This generates the following error message:
javax.faces.el.EvaluationException: Cannot get value for expression

What can I do to solve this?
