Web Component Tutorial

A report can have multiple headers. The reason you placed the header and footer as the

first and second component in the report’s View page was to have them registered by the

report generator before any body views. Perhaps the table of hosts in your environment

spans more than one page. If the footer was placed after the table component, it

wouldn’t appear until after the table. In fact this is true even if the table contains only a

few rows. The report generator would delay emitting the footer until the page after the

table was drawn. In the first part of this exercise, there is no page after the first, so the

footer wouldn’t appear at all.

Therefore, to switch headers or footers, place the new header or footer component

before the view that should begin the new page. If necessary, emit a page break between

the header and the new component. Using this technique, it is possible to have different

headers and footers in all sections of a long report.

Normally, you would choose your first body view to fit on page one. But what if you

want a new header on the second page and the first page must contain a table or other

view that may be several pages long? The first header encountered controls the first

page, but if the first body view may be several pages long the header or footer won’t

change until the whole component is written out. The solution may be to place a thin,

empty component after the first page’s header and footer, and then place the next header

and footer before the multi-page component. The system will place the first header and

footer on the first page, emit the empty component, set the header and footer for the next

page, and begin emitting the multi-page component. This will cause the second and

following pages to have the header and footer you want.

Try adding a header for the individual host pages. Place this header component just

before the iterator in the report’s Views pane.
