Thanks Gasper!

I reproduced the bug here and also verified the fix. I created Mantis entry
298 to track the issue and committed the patch to CVS. The fix will show up
in R3.14.10.

cvs diff -- casStrmClient.cc (in directory
C:hillR3.14.dll_hell_fixepicsbasesrccasgeneric)
Index: casStrmClient.cc

Subject: Re: gateway problem

Hi All

I checked also on gateway 2.0.0.0 with EPICS base 3.14.7 and it fails to 
do a caput -a  to waveform with FTVL set to DOUBLE.

I looks like the problem is in file casStrmClient.cc of generic ca server.

Primitive type is changed to aitEnumFixedString on line 2164 (EPICS 3.14.9)
pDD->putRef ( pData, type, pDestructor );

I changed this line to
pDD->putRef ( pData, bestWritePrimType, pDestructor );

and is working.

Best Regards
Gasper
