I have a bsv were I noticed that the results of a user generated query would not display results in the grid (several of the columns were blank). However, when I clicked on the 'Convert results to printer friendly format' or export to csv buttons on the grid the columns would then display the data.
I thought that maybe there was something wrong with the bsv so I took a blank CRM demo app and loaded it. I added the manage and run queries items to the menu and then created a simple query against the Customer BO. The results were better but it still had 2 colums that were blank (locale and Date of Birth) but displayed results when exported or sent to printer friendly format. Except Locale which did not have data.
I also tried modifying the query to display specific data or all data and it had the same end results.
I tested this in both FF and IE with the same results. I am on version 1246 running on Windows XP Pro.
