When memcache is enabled, all queries result same values

[raakeshkumar]

I have a Model ImplementingAgency.php
ImplementingAgency extends ActiveRecord\Model {
static $cache = TRUE;
function Targets() {
$count = Model1::find_by_sql("select count(id) as total where implementing_agency_id = {$this->id}");
return $ocunt[0]->total;
}
function Assignments() {
$count = Model2::find_by_sql("select count(id) as total where implementing_agency_id = {$this->id}");
return $ocunt[0]->total;
}
}

Now the problem is, when i call these two functions on same page, both return same result when cache is set to TRUE and when i set it to FALSE, both starts returning correct result.
Can you please tell why?

$this->id evaluates to the same value in both cases? If that's the case I think queries are cached over all models and not model independent..

Yes they refer to the current ImplementingAgency class instance from database. But i couldn't understand your explanation here. If you could please tell me how's it working?
