For the last few days we have been unable to create custom new/edit forms for External Lists in Sharepoint Designer. When i try to create a form Sharepoint Designer show the message 'Could not save the list changes to the server'. The corresponding
message in the ULS log file is 'Failed to find the default form for PAGETYPE PAGE_NEWFORM'. Does this mean i have somehow managed to break the form templates for External Lists?
I saw some other posts about the 'Could not save the list changes to the server' error and followed the suggested steps including removing all versions of the list and related content type, and recreatign htem but this didn't work.
