After some further testing I am relative sure that is it a bug from myfaces.
I hope with this post I can clearly descibe the problem.
I have set up a complete fresh
System:
- Tomcat 5.0.28
- MyFaces/Tomahawk 1.1.5
Bugdescription:
The getter of the Attribute "date" is not called by the convertDateTime when
you are using the var-variable which was set by the columns-tag.
(Test that by setting a breakpoint in the getter-Method of the
"date"-attribute)
Also try to add the following line after the inputText-tag to confirm that
the var-variable works correctly for other tags:
<h:outputText value="#{columnData.dateString}"></h:outputText>
It seems that all tags within "http://java.sun.com/jsf/core"; can't access
the var-variable which was set by the colums-tag. (That was not completely
tested but it seems so)
Further you can set a breakpoint to the line 197 in the file
"org.apache.myfaces.shared_impl.taglib.core.ConvertDateTimeTagBase.class".
- This method is called correctly (value is the EL-Expression
"#{columnData.dateString}").
- The method detects correctly that the value is an EL-Expression
- The correct value for the EL-Expression can't be found so the vale for the
attribute is set to null.
Here are my testfiles:
-ListItem.java-
public class ListItem {
private String dateString;
public ListItem()
{
dateString = "date";
}
public String getDateString() {
return dateString;
}
public void setDateString(String tollerString) {
this.dateString = tollerString;
}
}
-MyBean.java-
import java.util.ArrayList;
import java.util.List;
public class MyBean {
private List justAList;
public MyBean()
{
justAList = new ArrayList<ListItem>();
justAList.add(new ListItem());
}
public List getJustAList() {
return justAList;
}
public void setJustAList(List justAList) {
this.justAList = justAList;
}
}
