Creating a buffer in the Ajax viewer against a feature source contained in a MySQL database fails with the following error:

0 buffer feature was created

Warning: 1 layers were excluded from buffer computation because their coordinate systems are incompatible with the coordinate system of the map, or because they have no coordinate system at all

I have uncovered two bugs:

  1. !MySQL does not have an active spatial context by default. This can be easily worked around by selecting all spatial contexts in the buffer script instead of only the active ones.
  1. PHP does not honour the !bActiveOnly flag on MgFeatureService.GetSpatialContexts and GetLongTransactions. This is likely due to the presence of a default argument in the C++ header definition. The default argument will have to be removed for the API to function correctly in PHP.
