We have a custom field called "Test Case ID" that might be populated. We want to create a public custom query that shows all issues that have this field populated, in other words we want to query where Test Case ID is not null. If you set the filter to "is not" and leave the text box blank, it shows an error message that the text box must be entered. Please add "is not null" to the dropdown or allow the text box to be empty. This scenario is occurring more and more with a few different fields.

Thanks for the excelent work with Redmine!
