Previously, Service Dialog Import / Export wasn't importing All of the Service Dialogs and required importing two to three times before dialogs got imported.
Added SlickGrid plugins related to selections and checkboxes. SlickGrid uses an auto-adaptive display, where if the screen is too small or if the dataset is too large, it removes/re-adds rows to the table as you scroll. This was causing the issue where some of the items in the table weren't being selected to import. The fix was to use SlickGrid's built in plugins for handling row selection, and then serializing the data from the grid itself instead of from the form which has now resolved the issue.
