This is possibly the same problem:

Read through there is a solution further down. Backup your database first then try the solution. If it doesn’t work let us know.

Hmm i looked in the database cant see anything that has null value under entityname so im not sure…

4

how about entities with blank name?

5

there were no entities… i cleared out the database.

6

LOL, then how do expect “Select Entity” to be able to function?

sorry i mean that there is no entities in the sql table entities name like i deleted all the customer entities… so all i have as far as entities goes at the moment are Tables 1-100 but there is no data in the sql table… maybe im looking at it wrong. Ill post a screen shot in a few seconds.

TicketEntities will be entity assignments to tickets, not the entities themselves setup in Samba

Try the Entities table (dbo.Entities) ):wink:

Does this look normal then?..

I dont have any entities without custom data so not sure what that should look like if none configured but tables look to be entity type 2 and guessing thats customers as type 1.

Show a screenshot of your entities list in settings within samba.

Looks normal.

Check your Ticket Type to ensure you do not have any Entity Types listed in there that do not exist.

So if you have no Customer Entities, or more to the point no Customers Entity Type, you need to remove the Customers Entity Type from the Entity Type List in your Ticket Type.

16

well im using a blank database so i havent created any yet… I do want to be able to create them…

17

This error only happens when i choose a table entity from the tables entity screen… weird thing is that if i go to search customer and choose search and choose a customer and then close the ticket and go back to the tables screen it then lets me choose from that screen…

18

What have you got in your entity types page (entity section)
There were 2 entities of type one in the list, I would have thought the entities list would have showed them at top of the list as type 1…
How did you clear the database? via SQL Managment? as database tools doesn’t remove entities…

19

This is what happens when i choose a table to create a ticket…

then if i choose to select a customer entity it works fine… even if i go choose a table entity after a customer entity the table selection then works…

Try this:

Remove Tables from your Ticket Type and save.

Add Tables back into your Ticket Type and save.

Also, show the settings for your Table Numbers entity Screen.
