I am getting this problem and unfortunatelly search
tool for the list is off line right now.
So, I am trying to populate the form with general
options before submitting. I am doing something like
this, right off the struts HOW TO
<html:select property="colorSelected">
<html:options property="colorOptions"
name="orderEntryForm"/>
</html:select>
where colorSelected is a String with getter and setter
in the orderEntry form bean, and colorOptions is being
returned by a getter in the same bean as an ArrayList.
Something like this:
public ArrayList getColorOptions() {
colorOptions.add("red");
colorOptions.add("green");
return colorOptions;
When I try to run it, I get
ConcurrentModificationException which as an exception
is not always accurate but usually means that one
thread tried modifying the List while anohter one was
iterating. What am I doing wrong? Could someone point
me in right directions or maybe show an example.
Thank you very much.
Fedor
