I'm trying to do ajax for the selects - two droplists, categories and
subcategories.
When I click one of categories, then subcategories should make a
response - via observeField

I didn't see any errors in the firebug,

The POST data is -

data%5BCategory%5D%5Bid%5D=1

As you can see - it's returning id

the response mentioned the error -

 Call to a member function link() on a non-object in <b>/home/peter/
workspace/SheetCenter
/app/views/layouts/default.ctp</b> on line <b>8</b><br />

I'm not sure what it does mean. The line 8 consists of -

echo $javascript->link('prototype');

I'm following the tutorial -

I have been working on this for 2 days, and I didn't see anything
wrong with my code. Perhaps, I'm missing something.
