No result defined for action and result input error

This error is not defined for the returned input, but sometimes we do not need this ghost thing. However, if an error occurs in the action, the input is returned by default, if we define it in struts <result>, the error "no result defined for action and result input" is displayed.
There are many causes for this error, and path errors are also one of them. The types on the page and the types of the properties defined by action are inconsistent, leading to errors in background type conversion, does not enter action at all. (I used the parameter passed by jqgrid. The background is of the int type)

 

Solution: The best thing is that the corresponding attributes of action and post are set to the string type, which saves trouble and will no longer cause this error, and then execute the conversion in execute. This facilitates errors.
