Enable Communication
Between Cognos Portlets
You can enable portlet-to-portlet communication so that
the portlets can interact. For example, you can use this functionality
when you want to navigate published Cognos reports and view the
selected reports on the same page.
This functionality applies only to Cognos portlets and works
only for portlets of the same group. In each group, one portlet
is a target portlet, and the remaining portlets are source portlets.
The results of actions in the source portlets are shown in the associated
target portlets.
Portlet-to-portlet communication can be enabled between the source
and target portlets in the following portlet groups.
|
Cognos Content | Cognos Navigator | Cognos Viewer |
| | Cognos Search | Cognos Viewer |
| | Cognos Viewer | Cognos Viewer |
Metric Studio Portlets | Metric List | Cognos Viewer |
Cognos Utility | Bookmarks Viewer | HTML Viewer |
| | Image Viewer | HTML Viewer |
| | RSS Viewer | HTML Viewer |
To enable this functionality, you specify a channel name in the
target portlet and refer to this name in the associated source portlets.

Steps
Choose the portlet group for which you want to enable portlet-to-portlet
communication:
For the Cognos Content group, go to the
page that contains the Viewer portlet, and click the edit button 
in the portlet title bar.
For the Cognos Utility group, go to the page that contains the
HTML Source portlet, and click the edit button in the portlet title
bar.
In the Channel name box, type the
name you want.
The name can contain letters, numbers, and underscore (_) characters,
but must not contain any spaces. For example, Cognos, Cognos_Portlets,
CognosPortlets are valid names.
Click OK.
Go to the page that contains the source portlet you want,
and click the edit button in the portlet title bar.
The source and target portlets can be in different pages.

Under Open links, in the In
a destination portlet box, type the channel name specified
for the associated target portlet in step 2.
Click OK.
