ah ha.
jdk 1.4.2 :)
Well, i noticed that a similar method was working... and the trick was to
give them different names:
public List getCostList() {
return cost;
}
public String getCost(int index) {
return (String) cost.get(index);
}
This way,
${multipleProgrammesForm.costList[programme]} works fine
and <html:text property="cost[${programme}]"/> also works fine.
It seems that if you supply an indexed and non indexed method with the same
names, it gets all confused, and it tries to use the indexed method without
an index.
Thanks,
Daniel.
