We do this exact thing. In the Action that leads to the display of the jsp with the
multibox we use
the code below. Given an object (created from the database) that has an ArrayList of
the ids the
user previously selected:
ArrayList list = (ArrayList)obj.getCheckedIssueIDList();
if ( list != null)
{
int size = list.size();
String[] issueCheckbox = new String[size];
for (int i=0; i < size; i++)
{
issueCheckbox[i] = (String)list.get(i);
}
localForm.setIssueCheckbox(issueCheckbox);
}
In the localForm we have the following methods:
public String[] getIssueCheckbox()
{
return this.checkbox;
}
public void setIssueCheckbox(String[] stArray)
{
this.checkbox = stArray;
}
