[Lazarus] DataSource State not always current

[Alejandro Gonzalo]

In Delphi 3.02 this ALWAYS works, but only sometimes with Laz 1.0.6 for Win7 64bit w/ADS database:
  with DBNavigator1.DataSource do if State in [dsEdit, dsInsert] then 
 
 This can be fixed in Laz by adding a variable to the var section like so: myState : TDataSetState;
 
And replacing the above with the following 2 lines:
 
myState:=DBNavigator1.DataSource.State;
with DBNavigator1.DataSource do if myState in [dsEdit, dsInsert] then
