ServiceNow Bug with List type field?

[patricklatella]

Hi all,

seeing something strange.

I have a List type field that is set to "Use dependent field" = True.  I've set the "Dependent on field"...and then configured choices with the "Dependent value" set.

The odd behavior is that I am unable to select the first choice in the dropdown if no other selection has already been made.  You can see it in the dropdown, but you cannot select it.  Only after selecting another option can you then come back and select the first choice.

Anyone else ever seen this?  Thanks all!

In my screenshot, "Subcategory" is the "Dependent on field" selected.  I then have a few choices for the "Test List with Choices" field that have "Leaves" as the dependent value.  I cannot select the first choice in the dropdown.

Patrick,

What is the Value of Leaves?  Make sure the the dependent_value on the choice matches the value of the subcategory field not the display value.  Remember it is case sensitive, Leaves is not equal to leaves.

Hi Ricker,

thanks for the response.  Yep, the value is "Leaves" on the dependent field (which is actually a string field) and same on the choice in the "Test List with Choices" field...the issue is not that the correct choices don't show in the dropdown...the issue is that you cannot select the first choice in the drop down.  It's there, but clicking on the first choice does not add it to the List field.  You have to first select any other choice, and then you can select the first choice.  I've set this simple experiment up in my PDI, however I have a client that has this issue.  I mocked up a matching scenario in my PDI to verify this behavior is OOB...and based on what I'm seeing it is.  In my scenario above, "Subcategory" is a string field.

I've created a 2nd test, now the dependent field is "Dependent field", which is a choice field.  See my screenshots...I cannot take a screenshot with the dropdown open (it collapses when I use the snippet tool), but the correct choices are there in the dropdown when "Dependent field" = Blue.  However I cannot select the first choice, "One".

Hi Patrick,

I tried to reproduce it in my PDI.  I think it's the List field not playing nice with the dependent field.  Probably not designed to be used together.  The list field does not seem to work with the Choice List Specification...When creating a new record the List field does not use the dependent field to filter the choices.  Once the record is saved it will use the dependent field but not before.  Probably need to use a choice table and reference qualifier.

Hi Ricker,

so you were able to reproduce the issue?

I agree that it appears as though the List type field does not play nice with the dependent field logic...so maybe not a "bug" per se, but the system does allow you to set it up without any kind of messaging that the field won't work correctly. 

Your suggestion for using the choice table is a good one...I'll play with that and see if I get the same behavior.

Thanks for the dialog!
