Cacheable XSP with key based on jpath

[Frank Taffelt <fr...@interface-business.de>]

Hi,

i wanna make my xsp page cacheable based on the cache example included in
the samples.

If i understand the caching mechanism right, the processing order of an XSP
page is as follows:

1. getKey is called
2. getValidity is called
3. generate method is called

In my scenario the value of the cachekey can computed at first at the
generate method level, which is called after the getKey method. The reason
for this is the jpath taglib, that computes it's value inside the scope of
the generate method. But i need this value at the getKey calling level.

Do i have something overlooked?

thanks,
Frank

If I understand your situation correctly, this post at the wiki by 
Sylvain is just what you need:
http://wiki.cocoondev.org/Wiki.jsp?page=WritingForCacheEfficiency.
Put simply, provide the object during getKey but fill the object during 
generate.

HTH,
