Other things to consider...
Unless the form submission results in creating/updating a record, you might
want to do a GET instead of a POST request.
Instead of a single component with a form and some data to display,
consider two separate components -- one with the form, and one to display
the data. When the form is submitted, upon completion of the Ajax request,
you can have the second component load the data, setting it to reload
repeatedly. Your view might look something like:
{{=LOAD('performance_matrix', 'form.load', ajax=True)}}
<div id="data"></div>
Then in the form action:
def form():
...
if request.vars.some_field:
data_url = URL('performance_matrix', 'data.load',
vars=dict(some_field=request.vars.some_field))
response.js = '$.web2py.component("%s", "data", timeout=1000*60,
times="infinity")' % data_url
return dict(form=form)
Rather than handling everything via the index() function, have separate
functions for dealing with the form and generating the data output. When
the form is submitted, the above triggers Javascript to load the relevant
data in the "#data" div on the page. Because the value of the field is
encoded in the query string of the "#data" component's URL, every time it
reloads, it will display the same data (until the form is submitted again
and the "#data" component is overwritten with a new one).
