From: Zhou Zheng Sheng <zhshzhou(a)linux.vnet.ibm.com&gt; generate_action_handler() parses the request and collects the action arguments. The problem is it calls parse_request() in a generation expression. This implies parse_request() is called for each action argument. However parse_request() should be called only once, because it reads over the request body and turns it to a dict. When it is called a second time, the request body is already over, so parse_request() fails. This patch stores the result from parse_request() in a variable, and uses the variable in the generation expression.
