Hi AdminN,
I know that there is a is_number function. But I wont use it. Thank you for the suggestion anyway.
Use case: I want to get a custom query string value from url for pagination purpose. eg. http://...../?my-page-number=3
When I get this my-page-number from url, it will always be a string. I need to convert it into number.
But it is possible that url may be hacked by ?my-page-number=bar
My only intertest is why the "This widget cannot be displayed" only show up for non-admin users. I have been written so many custom components for lithium. And this question is alway bugging me. According to freemarker docs, attempt/recover looks like java try catch. So why Lithium show up this error message for users, not admins?
BTW, I am not talking about a string to number conversion here only. It is about the general attempt/recover.
