Hello,
I have a overview page with a dataTable-Component and a commandButton for each
row, to get to a detail page for the corresponding value. Since migration to
myfaces-1.1.0 this is not working any longer.
If I put the ManagedBean of my dataTable in session Scope, I have the values
of the table available, but if I do a
data.getRowData();
I always get the last row.
If I put the ManagedBean in request Scope the List which holds the data is set
to null, even if I use preserveDataModel = true.
Here my faces-config NOT complete:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces
Config 1.0//EN"
"http://java.sun.com/dtd/web-facesconfig_1_0.dtd";>
