Re: [Cppcms-users] Bad dynamic_cast! (http_context.cpp:150)

[Artyom B. <art...@ya...>]

Hi,


Because the content that you provide in the render function should
be a type of a subtype of the "uses" type for this template.

For example 

  <% view index uses data::index extends master %>

Should receive a content of type data::index or one derived
from it to render and you don't pass correct content.
