[Seaside] Bug/inconsistency in WAHtmlRenderer>>valueInputOfType:value:callback:

[Yar Hwee Boon]

File in the code and run it. Enter x and y in the textfields and hit  
submit. Now change the 2 values in #initialize from '' to nil and try it  
again, this time it should not work, because  
WAHtmlRenderer>>valueInputOfType:value:callback: does not call #fixTemps  
on the callback block when it is nil, at least.
