Dear Community,
Not sure if this is the right place, but here goes. I've upgraded an
application from 1.3.10 to 2.0.0 and now get the following error:
"Fatal error: Access to undeclared static property: DboSource::
$methodCache in /var/www/html/myapp/lib/Cake/Model/Datasource/
DboSource.php on line 3090"
I'm using a master-slave setup and have modified the AppModel
callbacks appropriately (as explained on one of the bakery pages). For
Cake 1.3 this works nicely, but on 2.0 I get the error above. I have
modified the cake code (I know I shouldn't :-) ) as follows:
Index: /var/www/html/myapp/lib/Cake/Model/Datasource/DboSource.php

public function __destruct() {
if ($this->_methodCacheChange) {
+ if (empty(self::$methodCache)) {
+ self::$methodCache =
Cache::read('method_cache', '_cake_core_');
+ }
Cache::write('method_cache', self::
$methodCache, '_cake_core_');
}
}
This solved the problem and I no longer get the messages. Is this a
bug and is my fix above the correct solution?
Many thanks in advance!
Kind regards,
Derik
