I've created a test module for DNN 3.1 with all the necessary projects and references but having some problems adding the module to the portal.  I'm able to add the new module but get the following error when I click 'Add Definition';

'Input string was not in a correct format.'

Module Name: HelloWorld
Folder Name: HelloWorld
Friendly Name: HelloWorld
Controller Class: <blank>

New Definintion: HelloWorld

I ran across this issue last night... there is a new field for a cacheing time; put a value in it. The form is errantly indicating that the blank entry in that field is an incorrect format. Technically, I belive that that field's validation should not be done until the "update" link is clicked. Bug?

Anyway, putting a value in it will solve this issue.

Thanks Mark, that solved it!

I ran across some minutes above testing the dnnJungle tutorial. Thanks a lot markjjordan
