Re: DB Maintenance Design Patterns

Paul, I changed the HTML template to display a check box in the list, to
be consistent with the check box in the detail panel.

http://www.onepoint.com/rdweb/temp/icecream.html


Under this design pattern the key to the record is embedded in the table
row (the <tr> tag). The key is asynchronously sent to the server by several
possible events (onClick, arrowDown, arrowUp, Home, End, etc.). Hence, the
detail panel is updated asynchronously as the user navigates the list,
using the mouse or keyboard.

Required fields are validated first using JavaScript, and validated again
on the server, using RPG, with appropriate error messages.

Nathan,

I like the presumed AJAX? to update the detail section of the page. I
assume the pattern is to display a list of records and a detail section,
and then onCLICK use ajax to go get the full record and display it in
the detail section? How do you know what complete record to get
onCLICK? Do you use the icecream key field?

A few questions:
1. How can we handle required fields? For example, I added
"strawberry" but failed to enter the other fields. We need a easy way
to enforce "required fields"?

2. The available field seems to be a 1/0 boolean field. It's rendered
as a checkbox on detail but not on the subfile?

Thanks, Paul Holm
