Import broken in SQL Developer version 1.5.1

Question

I try and import a .csv file and one of the Target Table Columns has no Data Type, which is odd because it does or else it wouldn't exist to begin with.
I liked the older version. Less buggy and so much easier to use when trying to import...and it worked with xls.

Answer 1

I am having the same problem so I will provide my details.
I have a .CSV file with two columns - a county code and a county name
I try to load them into this table using SQL Developer 1.5.1 Import Data:
CREATE TABLE MVC_COUNTIES
(CODE VARCHAR2(1 BYTE) NOT NULL,
DESCRIPTION VARCHAR2(35 BYTE))
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
MONITORING;
CREATE UNIQUE INDEX MVC_COUNTIES_PK ON MVC_COUNTIES
(CODE)
LOGGING
NOPARALLEL;
ALTER TABLE MVC_COUNTIES ADD (
CONSTRAINT MVC_COUNTIES_PK
PRIMARY KEY
(CODE));
I can:
Select the CSV file
See the data in Data Preview (no header row)
I can chose the Columns and Order
BUT - when I get to the "Map Source Data to Existing Table", I can only see the column definition info for the Description Column not the Code Column. The Code Column just shows the name, Size/Precision of 10, Scale of 0 (which does not match the table def).
When I go to the next screen, Verify fails because the column is not mapped correctly. By going back and forth a few times, I am able to fake it out so that the Column Definition for CODE finally does show up right and is mapped correctly to the input column but, when I click Finish, no data is loaded and there are no error messages.
I don't know if this is what the first person who started this thread has happening exactly but it seems similar.
Any ideas or is this an extension of other Import Data bugs for this version?
