Parameter Pick List - How to remove 'blank' value

Hi,

I am using FME Desktop 2015.1

I have created a Parameter (Choice - Single selection) and populated my pick list with the required values 10,20,30. however, when the parameter is invoked, an 'additional' blank value is also included. Is there a way which I can remove this from the selection options as I do not want someone to make this selection? Admittedly, I could build a series of downstream test to check for the non-value, but if I can avoid having to do this I would prefer to.

Thanks in advance.

Rob

Did you check off Optional checkbox? Also, did you define default value?

    Hi @zzupljanin

    Yes, I did both those things.

    I have discovered that it was user error! Apologies. A 'blank line' appears in the parameter definition dialog, and also appears when you select the parameter in the navigator window. But when you actually please workbench 'play' and the parameter dialog appears the blank line is not present.

    Apologies.

    Hi @zzupljanin

    So when you run the process and the dialog fires up then the blank line is not in the drop down (it was misleading me as I was making the selection directly, but not actually playing the process.
