Custom field checkbox value not respected in List Columns business map issue

[radu]

Hello again,

I have a List Colums type business map that defines the sales order columns displayed in the related table of other modules. If i add a custom checkbox field in SalesOrder module and define it as a column in the business map, the values displayed in the 'related' table are always 'no' even when the checkbox is 'yes'. Other built-in checkbox fields(ex. invoiced) are shown correctly. I tried to define the column both 'simple' and 'detailed', same result:

Code:

<field>
   <label>Checkbox</label>
   <name>cf_1410</name>
</field>

or

Code:

<field>
   <label>Checkbox</label>
   <name>cf_1410</name>
   <table>SalesOrder</table>
   <columnname>cf_1410</columnname>
</field>

Any ideas?
Thanks

-Later Edit- In fact, other types of custom fields show the same behavior, displaying wrong/no values in related table after defining List Columns business map. Do those columns representing custom fields have to be defined differently?
