My report items need certain JavaScript to be present on the page. Without modifying the viewer's JSP files the only way to do it seems to be to create <script> tags in onRowSets(IBaseResultSet[]). However, it would be inefficient to generate the same script for every instance of the item. Is there a better way to ensure it's only generated once per page than using context.get/setPageVariable?

Alexey,

If you add a text element to the top of a report and use a src tag for
it like:

<script type="text/javascript"
src="http://localhost:8090/WebViewer/myjsfile.js"></script>

The script tag should automatically get moved to the HEAD tag of the
viewer and be available on all pages of a report. It only does this for
script tags that use the src tag.
