If we make a "Set Selection" to a table and immediately after, we use an Action like "Table Get Column Value" without specifying the line index (therefore passing the value zero), Kalipso returns an error, saying: - Trying to get value from selected line, but there is no selected line! This happens because the Action "Set Selection" sends a message indicating that a selection should be done, but Kalipso doesn’t control when this selection is done. So Kalipso tries to execute immediately an action that doesn’t work by message. This action is executed immediately, but doesn´t indicates the line index and the selections wasn’t yet done. Therefore an error is returned. To resolve this issue you only need to pass the same index to all table actions where you have to use the line index and that index can be zero.
