OnClick on an "html select" not working for me in Seaside 3.0

Greetings,

I am attempting to display a list and trigger a callback onClick when
the user clicks on an item in the list.

The list is displayed correctly and when the user clicks an item I get a
debugger saying:

'This block expects 0 argument(s) but is invoked with 1 argument(s)'

I had similar code to this working in Seaside 2.8 but it is failing in
Seaside 3.0.

renderContentOn: html
| listToDisplay |

listToDisplay := OrderedCollection new.
listToDisplay add: 'AAPL'; add: 'INTC'; add: 'GOOG'.

(html div)
id: 'passedPanel';
with:
[(html div)
id: 'passed';
with:
[(html select)
id: 'passedList';
list: listToDisplay;
selected: (listToDisplay at: 1);
onClick: ((html scriptaculous updater)
id: 'foo';
triggerFormElement: 'passedList';
callback: [self openStock])].

"this div is a dummy div for the click to work - its
a kludge"
html div id: 'foo'.
]

Any help would be appreciated.

Thanks,
Frank

This looks similar to some strangeness I saw.

try putting the script first in your cascade like so:

(html select)
id: 'passedList';
onClick: ((html scriptaculous updater)
id: 'foo';

triggerFormElement: 'passedList';

callback: [self openStock]);

list: listToDisplay;
selected: (listToDisplay at: 1).

I tried your suggestion to no avail but I did fix the problem. When I
looked more carefully at the error message I realized what it was
complaining about. The fix is to add an arg to the callback block.

callback: [:r | self openStock]);

I am pretty sure that in Seaside 2.8 the callback worked as a zero parm
block.

Thanks for you help, it got me on the right path.
