Sorry, I forgot to mention that I'm a newbie.  Just tried to implement this but no luck.

 

How do I use WASelectTag>>beSubmitOnChange for this example?

 

Say I have a Dictionary (colourSizes in class named Product) set up where the key is the colour and the value is an OrderedCollection of the corresponding available sizes.

 

" The colour select box "

    html select
     beSubmitOnChange;
     size: ???

     list: (Product colourSizes keys);
     selected:

     callback:

" The available sizes select box driven by the choice from the colour select box "

    html selectFromList: 

     selected: 
     callback:

 

Cheers,

 

Dirk
