Reloadable pages

[Scott Russell <sc...@hotmail.com.au>]

Hi all,

Currently, as I understand it, Tapestry by default does not reload .page 
or .html template files when they are modified, unless the JVM property 
-Dorg.apache.tapestry.disable-caching=true is set, in which case .page 
and .html files are never cached, and loaded dynamically every time.

Thsi seems to me to offer two extremes - either no caching (with the 
performance penalty of constant reparsing of the files), or no dynamic 
modification at all.

Would  it be difficult to run, within the main Engine, a thread in the 
background that monitored (every minute or so) all loaded .page and .html 
files, comparing them against the last recorded update time, and reloading 
them if they have changed? This is basically what is done for jsp pages and 
it seems to work fine. And it would allow for dynamic modification of the 
tapestry .html and .page files, without the performance penalty of completely 
disabling caching.

Any thoughts on this?

regards,
Scott
