RE: How to change errors.header and errros.footer Dynamically????
???
Actually, another alternative would be the ability to change which message
keys are being used, instead of changing the resources themselves. You can
presently (at least in the nightly build) change the "header" and "footer"
keys for the "messages" tag, but not the prefix or suffix, and none of those
for the "errors" tag. I recently submitted an enhancement request to
address this for both tags. I was hoping to get more feedback on that in
the next day or so.

RE: How to change errors.header and errros.footer Dynamically???????
Posted by James Mitchell <jm...@telocity.com>.
I get around the internal (MessageResources) caching by getting the
protected Hashmap and flushing it:
...
// Override the default behavior of MessageResources caching
if (clearCache){
synchronized (formats) {
formats.clear();
}
}
...
...
By making clearCache configurable, I can set it to false for performance >=
normal except that I do not load an entire set of properties (as is done in
the default impl), but they are retrieved by key when requested (through the
app). In this case the app starts quicker, but is a bit (by milliseconds)
slower until all the messages have been retrieved (and cached), which takes
a while, depending on number of users.
