Newly created item through personalization not visible

Question

Hi All,
I have added on new item , in a page,
Howerver when I clicked apply on that item , once I define the required properties of the item.
I am getting this error
"Attachment item "%ITEM" has been created successfully, however, it does not have an Entity Map associated with it. To avoid a runtime error, please either create an Entity Map for this attachment item, or delete attachment item "%ITEM"."
I am not able to locate that item , anywhere * either in personalzied page nor in application page

Answer 1

I have gone to personalize page -> selected LOVRN -> create item ->
level - Site
Item Type - MessageLOVInput
Prompt - some custom prompt
Id - some custom id
External LOV- given exisitng seeded path for LOV with region name in the last
apply .
Then the error appeared as
Attachment item "%ITEM" has been created successfully, however, it does not have an Entity Map associated with it. To avoid a runtime error, please either create an Entity Map for this attachment item, or delete attachment item "%ITEM". appeared
After the above steps complete. I have again gone to personalization ->complete view . But I am not able to locate the item created in above mentioned steps.
One thing to note, I have tried creating new item , however everytime I am getting the above error after clicking on apply. In one occasion I have given incomplete path in the external LOV field mentioned above.(i.e. I forgot to mention the region Name )
Please help....
