Hi,
I supposed that my browser isn't submitting requests twice, because this
feature just only happens when I work with tiles. If my mappings use
forwards to jsp pages, everything works OK.
I've been investigating a bit more and I've found the exact point when
everything happens: trying to forward to mapping forward (In
RequestProcessor.java line 1057 - rd.forward(request, response);)
This is a snapshot of the two stack traces.
The first execution is finishing and trying to forwarding:
Thread [http-80-Processor24] (Suspended)

HttpServletRequest, HttpServletResponse) line: 1057
TilesRequestProcessor.doForward(String, HttpServletRequest,

And then a new Thread is created and my action is executed another time.

Asunto: Re: TilesRequestProcessor is executed twice
Ronnie-
I was looking at the stack dumps you provided and there are some
filters in there, possibly someone else has set them up. Regardless,
it doesn't look like that is causing your problem.
ApplicationFilterChain.internalDoFilter(ServletRequest,
ServletResponse) line: 252
ApplicationFilterChain.doFilter(ServletRequest,
ServletResponse) line: 173
Also, in the two stack traces, there is a doPost the first time, and a
doPost the second time. I've looked in the Struts source for
ActionServlet and there's no code in there that will submit a request
from doGet() to doPost() or vice-versa.
I know it's been asked before, but is it possible that your browser is
submitting the request twice, once as a get and once as a post? You
can verify this by setting a breakpoint at something earlier in the
call stack, say at ActionServlet.service line:802, and then seeing if
that breakpoint gets hit every time the breakpoint in
PartesMedicosAction is hit. If both breakpoints are hit, then it's not
something in Struts, so set your breakpoint back to something in
Tomcat, like one of the Valve classes.
