drag sources with no target

Hi -I have multiple drag objects but not all of them are mapped to a target. I am having a difficult time reaching the "success" state. Here are the details:

• The interaction has three drop targets with seven drag sources. Three of the drag sources are in a one-to-one mapping to the three drop sources.
• The option to auto-submit is selected.
• Upon "success" an advanced action script is executed, which displays feedback and navigation buttons.

I have tested the interaction, and after I drag the three sources to the correct targets, the feedback is not displayed. I am thinking that the "unused" drag sources are somehow holding back the "success" state. Do I need to set any other options? Thanks!
