Can you give us a code snippet to show exactly what you're doing?

Thats where I get Currently Errors
and here is the Error:
[ERROR] lua/vgui/dlistview.lua:107: attempt to index local 'Line' (a nil value)
1. RemoveLine - lua/vgui/dlistview.lua:107
2. DoClick - addons/msync/lua/ulx/xgui/settings/cl_msync_gui.lua:162
3. unknown - lua/vgui/dlabel.lua:232
it means this MSync.Modules.enabledModulesList:AddLine( MSync.Modules.enabledModulesList:GetSelected()[1]:GetValue() )
but i dont see anything wrong with it

I don't think it's that line. The error references RemoveLine, but the line you're saying is causing the error doesn't remove a line; it adds one. My best guess is that it's the next line, but I can't be sure unless you give me the entire file so I can cross reference the line numbers. I'm on an airplane now, posting this via the in-plane WiFi (painfully slow in-plane WiFi, might I add. But I am on a plane, thousands of feet up in the air, so I'm not sure why I expected better), so I can't test what DListView:GetSelected returns. But my guess is that when it returns a table of the lines (according to the wiki), it's not returning a table of the line numbers. I'll do some spelunking in the code for DListView to see what exactly GetSelected returns and how to get the line number from a line (because it doesn't seem to be documented in the wiki) and get back to you.
edit 2: The magic of GitHub strikes again. If the version of DListView_Line on GitHub is to be trusted, then you should be able to do something like Line:GetID() and supply that as the argument to DListView:RemoveLine(). I should probably be a good citizen and document this on the wiki, but I'm lazy and not looking forward to waiting for the page to load on this slow WiFi. Maybe once I get home.
An additional, less important, fact is that DListView:GetSelected()[1] is identical to DListView:GetSelected() (according to the wiki, at least. It's proven to be less than accurate in the past, but usually pretty good).
edit: Looking back at the previous replies, I'm very much confused what this has to do with XLib or making things invisible.

GetSelected returns a Table cause it allows to give the full Selection back .. but strangely it stays Empty and says its nil but that cant be true .. i mean i see the entries.. also it is add line cause remove line is doing its job but re adding the line to the other table doesent work

I'm not sure what your issue is. Are you still having errors?
