Can you report this to support.mendix.com via the feedback button on the right side of the screen.
This is a failure in the page creation that multiple persons have encountered, see https://forum.mendix.com/link/questions/98698 or https://forum.mendix.com/link/questions/98692 in which there is this workaround described:
Here is my workaround while waiting for the fix : on the left panel, go to “Pages” duplicate page “TaskOverwiew” which has the same required layout (tasks_TopBar) rename it into “SLA Dashboard” go back to “Navigation Document” on the left panel and now you can associate the SLA Dashboard page to your menu item You will have unwanted widgets/blocks below the top bar (because of duplicate from another page) but I suppose it will be easy to delete and replace them afterwards.
If the container is a dataview, check if the option editable of that dataview is set to yes
Thanks for quick response. But can you please tell me how to set dataview editable option?
I am completely new to this platform.
Thanks in advance,
FYI: We’ve just released a fix in Mendix Studio for this issue.
The Create button in the Create Page dialog works again as expected.
