Hi all,
I have a very strange thing. I have a multiple select in my JSP, and a
List<Long> of ids in my Action. When I submit the form, I iterate on that
List of Long, and I have this error :
java.lang.ClassCastException: java.lang.String
Struts has String in the List instead of Long. The strange thing is that it
appends on some servers (TomCat 5.5) but not on other : it works on my local
computer, bug on the test server, works on the production server, and works
on all other servers.
I first thought it was a Struts dtd cache version problem on the Eclipse of
the person building the WAR, but I have the same problem on my Eclipse
(which build working WAR for other servers).
We copied all jars files from shared/lib of a working TomCat to the bugging
TomCat, but it doesn't fix the problem.
Did someone already see such a thing ? Do you have an idea of where it could
bug ?
Thanks a lot.
Here is my code :
JSP : (id is a long, nomComplet is a String)
<s:select id="selectCommercial"
name="idsCommerciaux"
list="listCommercial"
listKey="id"
listValue="nomComplet"
cssStyle="width: 200"
emptyOption="true"
multiple="true"
size="10">
</s:select>
Action :
private List<Long> idsCommerciaux;
public List<Long> getIdsCommerciaux() {
return idsCommerciaux;
}
public void setIdsCommerciaux(List<Long> idsCommerciaux) {
this.idsCommerciaux = idsCommerciaux;
}
for (Long unCommercial : idsCommerciaux) { //ClassCastException here
Struts2 version : 2.1.0
