protected function calculateCacheKey()
{
$options = array();
foreach($this->getOptions() as $key => $option)
{
$options[$key] = $option; // <-- remove string conversion
}

return md5(var_export($options, true).$this->getBaseHref().$this->getPage());

}

Try this and let me know if it works...

Best.

[jrencz]

made it other way:
protected function calculateCacheKey()
{
$options = array();
foreach($this->getOptions() as $key => $option)
{
$options[$key] = (is_array($option) && (count($option) > 0)) ? (string) $option : "";
}
return md5(var_export($options, true).$this->getBaseHref().$this->getPage());
}

somehow (I did not check how, it's custom widget, not diem one) $option was an empty array.
This is just temporary solution since I don't know what to do with not empty array. Maybe joint their contents into one string? Should probably work

1. $options[$key] = (is_array($option) && (count($option) > 0)) ? (string) $option : "";

vs.

1. $options[$key] = $option;
2. is better because it is less CPU and memory greedy, and anyway it will be obusfucated with MD5, see:

return md5(var_export($options, true).$this->getBaseHref().$this->getPage());

to be honest, this would be the best solution:

protected function calculateCacheKey() {

 return md5(var_export($this->getOptions(), true).$this->getBaseHref().$this->getPage());

}
