Hi!
I have an issue with editable table and don't know if is my mistake...
There is a simple editable table which uses a custom comparator.(is one of the
examples from the wiki page)
I'll post the exception and then the source files.
The exception is thrown in
class : [SerializableAdaptor ]
method : [squeeze(DataSqueezer squeezer, Object data) throws IOException]
line : [oos.writeObject(data);]
I understand that the problem is that ColumnCmparator should be
serializable .... What i don't know is if there is , and where is a mistake in
my code.
Here is the exception :
***********__________________***********
java.io.NotSerializableException:

-------------------------------
Source files :
-----page class -------
This is where i set the comparator :
public ITableColumn getBirthDateColumn() {
SimpleTableColumn birthDateColumn = new SimpleTableColumn
("birthDate","Birth Date",new BirthDateColumnEvaluator() ,true);
//if this line is commented i don't get the exception anymore
birthDateColumn.setColumnComparator(new BirthDateComparator());
return birthDateColumn;
}
-----------------
BirthDateComparator.java implements Comparable and also Serializable.
--------html page ----------
<table class="mytable" jwcid="[EMAIL PROTECTED]:Table" source="ognl:dataItems"
columns="SSN:SSN,firstName:firstName,lastName:lastName,=birthDateColumn
, height:height,weight:weight"
rowsClass="ognl:evenOdd.next"
pageSize="6"
initialSortColumn="birthDate">
----------------
So it apears that ColumnComparator should be made Serializable .... is it so ?
(or i did mistake ....)
Thanks a lot !
, Alex
