As I mentioned, I rarely use #call:, or #inform:.  But, here is an 
abbreviated example of when I do use it:

One of the components is BBItem, for showing an item for sale.  The 
#renderContentOn: method of it looks like this:
*****
renderContentOn: html
    " .. snipped some stuff .. "
    html
           form: [html bold: (item dollarFormatted: item salePrice) , ' 
' , item salesPack.
                      html space; space; space; space.
                      html
                             submitButtonWithAction: [self addToCart]
                            text: 'Add To Cart'].
*****

#addToCart is implemented thus:
*****
addToCart
    | ses |
    ses _ self session.
    (ses shoppingCart addToCart: item)
                ifFalse: [self inform: 'There is insufficient stock on 
hand to add this item add this time.  Please try again later!'].
     ses topComponent viewcart.
*****

And, the shopping cart #addToCart: method answers true or false 
depending on whether it actually added the item to the cart.  Currently 
the only reason why it won't add the item to the cart is if there is 
insufficient stock on hand.

And actually, even the above example rarely invokes #inform:, because 
the "...snipped some stuff.." code in #renderContentOn: keeps the submit 
button from showing in most such cases.

Avi, don't spend too much of your valuable time on this.  Give me a 
chance to look deeper first.  Besides, as I mentioned before, your newer 
Seaside2.3b4.st snapshot might not have the problem.  And also not to 
mention that there's still a reasonable possibility that it is my code. 
 If I remember right, the last couple of times I wrote about Seaside 
issues, they also turned out to be with my own code.  And you've been 
wonderful with your responsiveness.
