#181 TOutputCache problems

[Anonymous]

PHP 5.36
Prado Releaseversion 3.1.10

If I use TMemCache as Primary Cache I keep on getting this error or the same error in pradolite:

[Warning] call_user_func_array() expects parameter 2 to be array, string given (@line 190 in file /var/www/prado/framework_statista/Web/UI/WebControls/TOutputCache.php).

Error gets fixed if in the line(s) mentioned the second parameter gets cast into array. But is it correct to do so?
