Struts does not seem to accept a Vector-typed field as a property value. The
form simply fails to load.
I'd happily use LazyList and a Factory together instead of a Vector if it's
easy to implement...
First I wanted to get it working with Vector, then I can easily switch to a
different container.
------------------------------------
In my JSP:
<html:select property="vizsgalatEsOrvos[0]">
------------------------------------
In my bean:
private Vector vizsgalatEsOrvos;
public Vector getVizsgalatEsOrvos() {
return vizsgalatEsOrvos;
}
public void setVizsgalatEsOrvos(Vector vizsgalatEsOrvos) {
this.vizsgalatEsOrvos = vizsgalatEsOrvos;
}
------------------------------------
Instantiating my Vector in the constructor won't help...
Struts should call
myForm.getMyVector().set(0, ?)
Do I need to implement this metod? Do I need to write my own setters/getters to
do this?
How can I do this exactly?
Thanks,
MB
