Problems with dbLinkIsConstant

[Torsten Bögershausen via Core-talk <core-talk at aps.anl.gov>]

Hej all,

I have a problem with dbLinkIsConstant(), it seems.

If I run the motor module with this code:

#if LT_EPICSBASE(7,0,0,0)
#define dbLinkIsConstant(lnk) ((lnk)->type == CONSTANT)
#else
#include "dbLink.h"
#endif

And later

    if (dbLinkIsConstant(&pmr->dol))
    {
        pmr->udf = FALSE;
        Debug(pmr,3, "init_record %s\n", "dbLinkIsConstant=true set 
UDF=FALSE");

        recGblInitConstantLink(&pmr->dol, DBF_DOUBLE, &pmr->val);
    }

I get this log message:
 [motorRecord.cc:906  IOC:m1] init_record dbLinkIsConstant=true set 
UDF=FALSE

However, the .DOL field is empty.
Is this the expected behavior ?

EPICS base is here:
