thanks for your response.
We are testing ArcPad 10.2 Beta and 10.0.4 in évaluation. We have a licence of arcpad 7 and we should migrating in few month.
We use SHP because we encounter another bug with AXF import export (a mix of datas in the fields :s) and shp is used in many software.
We had created an applet with custom toolbar but the edit tool are not re-devloped (we have a custom edit form and and 3 tool button with minor functions, just select the edit layer in 3 point layer and show/hide raster)
To precise the bug : We have duplicate polygon in 10.0.4 version but we have delete polygon in 10.2 beta. Only for polygons and polylins we had insert a vertex.
Best regards
Matthieu
