I have a power table with data binded to an expression returning a source dataset.  
User can select only one row.  
When new data are added or dateted in the source dataset, I would like to keep the row selected by the user (in the case the row is still in the source dataset)  
each time a row is added in the source dataset, this row is selected bu default, and user row selection is lost.  
Any idea to achieve that ?

I don’t fully understand what you are asking, but maybe you could add a custom property that points to the rowIndex that the user last selected. I guess you could put the script in onMousePress extension function. Something like

```auto
self.customProperty = rowIndex

```
