ORA-00932: inconsistent datatypes: expected - got CLOB encountered

[Haris Tasawar，修改在11 年前。]

Hey all,
I recently created a finder method in my service builder as follows:

<finder name ="findbyall" return-type="Collection">
<finder-column name="MEETING_DATE"/>
<finder-column name="MINUTES"/>
<finder-column name="CATEGORY"/>
</finder>

(The MINUTES column is of type CLOB in database)
and ran the service builder.... now everytime i search using this finder method i get an error
ORA-00932: inconsistent datatypes: expected - got CLOB

I tried to change the portlet-model-hints.xml file and also updated the ext.properties file but still i am getting this error. Can somebody help me on this .
Thanks
Haris.
