We have recently converted configurable products in grouped product + get all linked simple product moved. All is ok on front. But in the back office, on the product edit page, the listing of simple products reached to the grouped product is incomplete. Only way to fix the issue and get the right list is to save it manually by clicking on the button. After the list is ok.
I have tried to get all grouped products and save it programmaticaly but the issue is still not fixed.
Any idea ?

Edit : I will try to correct my script and re-save all grouped products AND all simple products linked for each grouped.. keep you updated..
