Getting Object Instance of object type (whose super type is NULL) from DFC

gyanus

HI All,

The Below Line gets the Object Instance,if the custom type queried has a valid super type (like dm_sysobject or dm_document..)

  

IDfSysObject doc =(IDfSysObject) sess.getObjectByQualification("custom_type where pwc_r_status = 1"); how to get an object instance, if the custome type has a super type as NULL.

for ex: super type of test_object_type is NULL and the below line throws cast exception error

  

IDfSysObject doc =(IDfSysObject) sess.getObjectByQualification("test_object_type where pwc_r_status = 1");

is there any method (like above ) to get it? or i have to use IDfQuery class?

but some places i had read like IDfQuery is an costliest operation and should be avoided.

can anyone help on how to proceed? or where i went wrong? (if any?)

Is your object implemented as a Lightweight object or just a registered table?
