Hey guys, I am having some trouble with the following setup: Custom page that has several objects via a has_many relation. The objects on the other hand are related to a third object via a has_one relation. How would I handle this in the CMS as apparently it's not possible to open a popup within a popup. The page's getCMSFields has a HasManyComplexTableField that allows me to add data objects to the page, but how can I add data objects to the data objects as the HasOneComplexTableField I tried using in the first data object lacks the Add link in the popup (actually it's there in the markup, but it's set to hidden via CSS).

I know this is possible with ModelAdmin, but have no idea for editting a Page. Do you have...


...before you "addFieldToTab"?

Yep, but it doesn't work. I think popup within a popup is not supported. :-/

No, a popup within a popup won't work afaik, you can see the summary, but you can't edit/add anything. Could ajshort's HasOnePickerField maybe be used in this situation?
