The Popup Iframe of the DataObjectManager is 500px wide. How can I make it 600px wide?
I think it's "setPopupWidth()", no?
You're right UC.
using set_pop_width changes the static value of the class
whereas setPopupWidth changes it for a single instance of the class
So if you want all popups to have an alternate width use DataObjectManager::set_popup_width(...) in your config
If you want to change the width of a single popup use $oDataObjectManager->setPopupWidth(...)
