I have created a new feature using the MapThat Drawing Tools and added attributes, however when I choose to Save the new feature nothing happens or I get a message stating that the ‘Graphic has Failed’. How can I resolve this?
In order to ensure that your Drawing Tools can create new features within your Data Layers you need to set a value for the AutoNumber Type within the MapThat Admin Forms. Your data could possibly be stored in any number of spatial database types and these settings include:
- ORACLE - set the AutoNumber Type to be MAXVAL.
- SQL SERVER - set the AutoNumber Type to be IDENTITY.
- POSTGRES - set the AutoNumber Type to be SEQUENCE.
These settings ensure that MapThat can create a new record in either Spatial Database table using the id of the last record to create a new id.
If you are inserting records in to a SQL Database Table, ensure that you edit the DESIGN of the SQL Table and choose to set the IS IDENTITY value to be Y for the field that will be updated with the next sequential value – this is likely to be the Primary key field.
