help with multiple submit buttons

[Janne Mattila]

Quite often I need to implement a form that has several submit buttons - for 
example a page where several products are listed, and next to each product 
is a "delete" -button. Since clicking on each button sends only one 
parameter, I have to encode both the action and the id of the item into same 
parameter....for example

<input type="image" src="pics/delete.gif" name="deleteitem_146" 
value="somevalue">

When the image button is clicked, browser sends parameters that look like
deleteitem_146.x = 13
deleteitem_146.y = 21
This kind of parameter has to be "decrypted", by first running through all 
request parameters to find ones starting with "deleteitem_" and then 
extracting the correct id (in this case 146). Usually I do this with various 
custom made helper classes...

Does struts provide some sort of help to this problem? I have to say I am 
quite surprised if it does not!
