Help needed in TABLE list displaying a group of records

[Yuva Kumar R]

Hi All,


I am developing an launcher application in which I am using a Table to
display a single column and multiple rows data.

In the application, I want to display all applications with DATABASE TYPE as
"ovly".   I am getting blank lines in the list whenever a OVERLAY database
is read in the FOR LOOP.  I am giving below the code snippet where I am
reading the databases.

Please help.  Thanks and regards.
