I have no experience with Portlets (or Tapestry 4, really ;-)
but PageRenderListener methods being called twice is normal
operation for form submits.
- first for the form "rewind"
- again for the actual rendering of the page
The usual boilerplate code is something like:
public void pageBeginRender(PageEvent event)
{
if (!event.getRequestCycle().isRewinding())
{
// initialize properties etc
}
}
Cheers,
Nick.

Hi, i have one problem.
I use Tapestry 4.0.2 and have written a portlet with some heavy
operations(loading data from database and reading preferences from portal
server)
All this operations are working from this method
public void pageBeginRender(PageEvent event) {
...
my own heavy operations
...
{
In servlet case this code running once, but in portlet case twice, so i have
almost double response time for portlet.
Maybe one is action phase,another is render phase...
Is there two request absolutely equal or i can indicate each one by Tapestry
standard way?
Thanks.
