How can I add a workflow condition that prevents transition if work is logged?

Question

I want a Cancel button that closes an issue and sets the resolution to canceled.  However, this can only be offered if no work is logged on an issue.

I see I can use Value Field on Log Work, but I have not figured out how to use this properly.

I've tried = 0 as a string and a number, no good.

I've tried = (empty) as a string and a number, no good.

I know I have the correct field; I don't know how to configure the condition. I know this is the right field since I was able to get issues to fail the condition with Log Work = 0, but in that case, I was never able to get the transition to appear, even when there were no work logs.

I am concerned that this is simply not a possibility:

Hi Rob,

this should work:

Allow the transition to status "Cancel " only if the value of "Time Spent" is empty, with condition "=" and set as "Number"

Edit: Updated my answer with the working solution.

HI Rob,

You may need an add-on for this to extend the Current capabilities of the conditions. This may be less than ideal, but can use validator so when a user clicks on the cancel button, it will be rejected if there is time log.

There's was a similar situation but exactly in this post:
