I'm installing my first silverstripe site. I've installed Uploadify, Kickassets and tried to install DataObjectManager before I realised that it wasn't compatible with 3.0.5.
I have an issue when I try to go to Browse Files in the admin, I get the following error message Error at line 469 of /home/sitename/public_html/framework/model/DataList.php
Line 469 is "throw new InvalidArgumentException(sprintf('Filter class "%s" does not exist', $className));"
private function applyFilterContext($field, $filter, $value) {
$t = singleton($this->dataClass())->dbObject($field);
$className = sprintf('%sFilter', $filter);
if(!class_exists($className)) {
throw new InvalidArgumentException(sprintf('Filter class "%s" does not exist', $className));
}
$t = new $className($field, $value);
$t->apply($this->dataQuery());
}
