I'm selecting cables en hit "Apply" but i get the message that there is no cable selected and all the cables are shown in the report.

So I found the problem. When you check a box you need to select another row to get the first cable. So if you select multiple cables and you forget to click another cable you always miss the last cable.

Also when making a selection and creating a report, it isn't possible to change the selection. Because only the selected cables are shown. When you click refresh all the cables are selected again and your selection is gone.

So the first problem of selecting is fixed but when going back to the "cable data selector" only the previous selected cables are shown. There is no way to select more cables.
