Subject Re: New AliasBean component
Date Wed, 10 Nov 2004 10:49:04 GMT
How about having a close that removes the alias?

So you could do;

alias valid...
alias not valid...

So in encodeBegin(...) the alias is made and in encodeEnd(...) the 
alias is removed.


I personally like this approach better because it is more explicit and 
if you have more than one subform on the same page the coming and going 
of the alias would be explicit (probably helping me find bugs, or 
preventing me from introducing them).
