11.2.1 Recommended procedure
In general, you can follow this procedure to create combined integration output in
your application from sequenced Integration Objects, using the Host Publisher
Studio wizards, as follows:
1. Create a new application.
2. Import the Integration Objects into the project.
3. Define the first Integration Object in the logical sequence first. Specify how to
provide input to this Integration Object, if applicable (using another form page,
for example). Do not render any output from this Integration Object on the
page. The output is used by the next Integration Object.
4. Define the second Integration Object. To satisfy its inputs, specify that they
are to be satisfied using other Integration Object output.
5. Select the other Integration Object from that page as providing that output.
Note that Integration Objects only accept single-value inputs, so you can only
use single-value outputs from other Integration Objects as input to another
6. Render the output of the second Integration Object on the page.
You should have two pages in your application. One page requests input in an
input form and delivers it to the other page. The second page executes the first
Integration Object using the input, executes the second Integration Object using
the first Integration Object's output as input, and displays its own output on the
If required, more Integration Objects can be added to the page to lengthen the
11.3 Sequencing Integration Objects on multiple pages
You can use multiple Integration Objects to return data to the user in steps,
allowing the user to act upon the data and return selected data for the next
Integration Object to use.
For example, Figure 11-3 on page 324 illustrates an application with three pages.
The first page uses a phone number lookup application to request a name (input
page). The second page displays all matches found (execution page 1), allowing
the user to select one. The third page displays the phone number of the selected
individual (execution page 2).
