Charles' notes: This looks to be a DataExpress issue -- see this code in DataSet.getDisplayVariant():

if (dataSetStore.provideMoreData())

Note that more data is being provided by dragging the scrollbar, so that the selected row is not changing. I also attached a JDS version of the customer's project.

[QC Short Description]
JdbTable Scrolling broken when dataset is opened as Load.AS_NEEDED.

[QC Description]
Everytime the table scrolls down to the end of the currently loaded records, (using scroll bar), the table refreshes to the currently selected record,  and a spurious navigation event is generated.  
QC Entry 8540

[Additional Notes]
Customer purchased a support contract and wanted this promoted from Quality Central into Raid.  He provided a test case with instructions.  However, his test case is reliant on MySQL, so I haven't actually tested this.
Steps to Reproduce:
dataset is opened as Load.AS_NEEDED.
-connected to JdbTable within TableScrollPane
- use scroll bar to scroll down
- when scrollbar reaches end of displayed records, data is refreshed from the database
and display is reset to previously selected record.
- navigation event is generated  to previously selected record. (redundant)

[Customer's Test Case]
Extract the file and there is a file called TestCaseSteps.txt that lists the customer's steps to reproduce.
The table should be using a dataset view to generate the display,
or disable navigation events while refreshing.
