getItemData integration api: unable to read data for custom item
I am trying to retrieve the data of an custom item via the getItemData api but i am gett the error message
"Not implemented for this item type"
I checked the api documentation, the list of supported item types include custom methods.
Is there any thing that i need to maintain for the custom method so that i can read the data stored by it using the getItemData api.
or is it simply not possible to read custom item data.
Thanks for the help,
