Created attachment 194561 [details] Snippet for virtual table viewer with add and refresh button Hi, In my project I found that on add, a virtual table seems to break. It still adds elements to the table view, however it adds the wrong ones. this is a somewhat more detailed description (I'll attach code at the end) : Create a table viewer that is virtual and add a comparator to it. Then add elements that would appear at the beginning of the Viewer. When calling add, the tableviewer adds a new element, but since it is adding it to the end, it retrieves the last element of the model. Due to the sorting of the model, the newly added element isn't at the end and the wrong element is added to the view. This seems to be an indexing problem with the viewer. The correct element is created and calling refresh on the viewer will make everything appear in the right way. I used Tom's TableViewer sorter and changed the code so the UI has an add and a refresh method. Calling add will add elements that start with the index 1. The comparator will put them on top of the viewer and they won't be visible. After clicking refresh, everything works fine. Best regards, -- artur
