I see error messages in custom URLs

If incorrect information is entered in the decorated URLs, you may see these error messages.

• No Geognosis SWD layer added to the WML Map
  
• No layer found that matches the "overlayname=" value
  
• Network/GeognoSIS server connection error (GeognoSIS can't be contacted, or throws an error)
  
• No value matching "schemacolumn=" and "UID=" values in the generated expression.

The schemacolumn must always be string type.

The SIS expression is formed by appending a $ character to the schema column name and the UID value is surrounded by quotes:

"schemacolumnvalue$='UIDvalue'"
