Calling flush or invalidate from template
Hi all,
I would like to call Roller.flush and/or CacheManager.invalidate from a
template.
I can't figure out how to do it.
Any idea?
regards
Eric

yes, unfortunately Erik is correct, all of the wrappers have a getPojo()
method which provides access to the original pojo.
the reason for this is because there are parts of the model code which
required access to the original pojo to work, so that method had to be
added. of course it's undocumented, unsupported, and as soon as we can
remove it we will.
in any case, as Dave suggested, you shouldn't be modifying data via your
templates. they aren't designed for that and that will never be
supported by Roller.

Hmm, believe me Dave, from the wrapper, i can call the "getPojo()" method and have the pojo ;)
I change the category from my template, i only can't flush the cash, and have to do it from the admin ihm.
But don't worry, i'll use a task instead.

Actually, you can only get POJO wrappers -- which are not persisted in the database.

Actually, you can only get POJO wrappers -- which are not persisted in
the database.

Oh ok.
But from the wrapper, i can get the pojo. From the pojo, i can change some properties (in my case, i want to change the Category of an entry), but i can't call the save method of the pojo, neither flush the cash.
Well, i guess i will do what i wanted to do through a scheduled task.
Thanks

Not possible with stock Roller.
We don't want template authors to call anything other than the PageModel and the POJO wrappers, so we don't make any backend objects available in the template context.
