DO Node(attachment)-Not working in change mode

Dear BOPF Experts,

I have created a UI Application which is susing BOPF Based BO, it has one ROOT Node, and one Attachment Node ( DO is : ATTACH_FOLDER ) .

Create Mode: When I am createing a new instance it allows me to insert any file/folder/link on Attachment Folder and its working perfectly.

Change Mode:In change mode when I press Insert Button on Attachement Folder 'File/Folder/Link options are disabled i.e. in change mode of my application its not allowing me to insert any file/link on attachment folder tab.

I have created my own BOOTSTRAP class for initail screen and one VIEWEXIT INETRFACE CLass to handle the properties, rest of the configurations are as per standard only.

Thanks in advance for any help !

Best Regards,

ST
