Symptoms

Problems using "Transfer data" with drop-down lists with a GUID value
 

Diagnoses

Our databases are developed with one large "Types" table that holds all the selections for drop-down lists etc. Recently, we have changed to using uniqueidentifiers i.e. GUIDS for the ID in this table instead of integersWe're currently having issues with "Transfer data". Below is an example scenario:

Drop-down list 1 with a choice of "Internal" or "External"
Drop-down list 2 with a choice of "High" "Medium" or "Low" from a SmartObject
When you change Drop-down list 1 to "Internal", Drop-down list 2 should change to "Low"

When we used integers for the ID in the "types" table, we used to use "Transfer data" to set the selection in Drop-down list 2. However, for some reason, this does not work with guids - nothing happens
 

Resolution

Bug has been logged against this, for now try to use lower case GUID on the Smartforms side or keep using the read method and K2 will get back the GUID as lower case.
