Error with Edit form using Related Items.

[gervis.dillon]

I need help with fixing this problem.
I get this error when I try to edit a created item that was made using the Forms Designer New Form. The form has related items from another list located in the same site and it works properly. The display form also works as it should. When I try to use the edit button from the ribbon or the context menu I get this error.

404 NOT FOUND

this is the url i get when the error comes up.

Code: Select all

/sites/home/it/~list/fd_Item_EditForm.aspx?ID=8&List=f246deff-de38-4b37-9ddc-e1c4e1fa78d2&Web=9f0d26ad-923b-41bb-a3c7-dc14c04a6838

this is the url of the display form before I click edit.

Code: Select all

/sites/home/it/Lists/IT%20Equipment%20Liability/fd_Item_DisplayForm.aspx?List=f246deff-de38-4b37-9ddc-e1c4e1fa78d2&ID=8

If you notice the path structure of the edit and the display urls are different.
The edit url has "it/~list/fd_Item_EditForm.aspx"
but the display form url has "/it/Lists/IT%20Equipment%20Liability/fd_Item_DisplayForm.aspx" which clearly shows why i am getting the error.
If i copy the display form URL and replace the URL path of the Edit form URL then the edit form shows up properly. So my question is how do I fix this problem?
