T5: Editing a list of values
My use case is this,
i would like to let the user to enter an undefined number of values. I
have the UI implemented with a loop component getting the number of
cycles from a page property and in each cycle it places a new textfield
component.
The problem is, what property do i put in each of the textfield value
paramters ? I'm holding the values in a List property in my page.
I can't do <input t:type="textfield" value="myList.0"/>.
Any ideas ?
I'm thinking that i may be complicating something that probably is much
simpler.

Your example solved my problem also, thank you :-)

I have a micky mouse example that does something

You could keep track of an index variable and use that to index a List in
your page class. Something like the following:
public String getValue()
{
return values.get(index);
}
public void setValue(final String value)
{
values.set(index, value);
}
Then the trick is updating the index value, but that may be simpler for you.
I've used that trick to avoid serializing Cayenne objects in a Loop. Of
course, in that case, the semantics of the index value are very well-defined
so YMMV.

Yep, definitely was over complicating.
I just have to use the value parameter of the Loop component.
