Hi,
I am having a problem with a multi-value widget.
The problem is this:
I am using a multi-value widget called Roles. It will
return a value of an array of integers.
So, my widget is defined as follows:
<fd:multivaluefield id="roles">
<fd:label>Roles</fd:label>
<fd:datatype base="integer"/>
<fd:selection-list type="flow-jxpath"
list-path="roleList" value-path="value"
label-path="label"/>
</fd:multivaluefield>
It populates correctly.
The problem is when I get user data and try to save it
to the database.
I get the infamous error:
org.apache.commons.jxpath.JXPathException: Exception
trying to create xpath roles[1]; Cannot access
property:
org.apache.cocoon.ojb.samples.bean.DictUser.roles;
java.lang.reflect.InvocationTargetException
My binding file is:
<fb:multi-value id="roles" parent-path="."
row-path="roles"/>
I am trying to persist the data to the database in a
column of varchar(100).
I am able to retrieve the data that I manually enter
into the database and select the correct labels in the
multi-value selector.
It is only when I try to save it, that I get this
error.
The get and set methods I am now using are as follows
(the get works, but not the set):
private String roles;
public Integer[] getRoles() {
Vector v = new Vector();
StringTokenizer strTok = new
StringTokenizer(roles, ",");
int i = 0;
while (strTok.hasMoreTokens()){
String val = strTok.nextToken();
Integer intVal = new Integer(val);
v.add(intVal);
i++;
}
Integer[] intArray = (Integer[]) v.toArray(new
Integer[1]);
return intArray;
}
public void setRoles(Collection arraylistroles) {
Iterator it = arraylistroles.iterator();
if(it.hasNext()) roles = (String)it.next();
while (it.hasNext()) {
roles = roles + "," + (String)it.next();
}
this.roles = roles;
}
Any help will be appreciated!
thx
Paul
