The Custom_Settings section contains a series of text labels that record the settings made in Step 7: Configure Properties. The properties contained in these text labels apply to the Interactive Reporting document as a whole. The section includes properties such as the Home frame, and the status of toolbars, menu bars, and so on.
No JavaScript is contained in this section. The settings and JavaScript are kept apart so they can be modified separately. Oracle or a third party with JavaScript and Interactive Reporting Studio object model skills generally provide the JavaScript, and this is common to all dashboards built from that template. The dashboard developer provides the settings for the dashboard that are specific to the dashboard.
The separation of code and data enables Oracle or third party developers to provide updates to the JavaScript without compromising the settings you make.
Updates to templates and dashboards are provided as an Interactive Reporting document with one or more sections. Old sections are removed by the Dashboard Development Services Update Utility (see Using the Dashboard Development Services Update Utility) and replaced by sections contained in the updated Interactive Reporting document. The Dashboard Development Services Update Utility is based on the technology that underpins the Import feature or Dashboard Studio Merge Utility. See Using the Import Feature.
