I am in a discussion in my government department and some of the opinion that the use of ExtJS without a licence could be a legal minefield</div><div><br></div><div>I have been using Extjs 3.3 with GeoExt 1.0 to make mapping applications. The Code I have written is open. The native ExtJS libraries are also open. Does this mean I can use them without buying a licence?</div><div><br></div><div>If anyone can shed some light I would be most grateful,</div><div><br></div><div>Yours,</div><div>Robert</div></div></body></html>
