When you create an application to display on a PDA or BlackBerry client, and you want to give users the ability to update the application’s source content from that PDA, link the source application with an update application, which acts as a queue to store updates on a PDA until the PDA is re synchronized with the local host computer on which Unwired Accelerator is installed.
First, you must create the update application, then you must create the primary application with a link to the update application (see Chapter 5, “Creating a Multipage Mobile Application with Transaction Support” in the Mobile Application Development Tutorial for instructions on creating primary and update applications).
For conflict resolution to work correctly on your update, you must also create a verification application and link the update application to it. The verification application must return a grid data set using a select statement based on the values of one of CGI parameters used as the search parameter. It must also include a header row that defines the columns of the grid. The column names must match the update parameter in the update application.
If conflict resolution is not an issue for you, there
is no need to create a verification application. All updates take
effect regardless of whether or not the value to be updated is current.
