action executing two times
I have an action mapping that looks like:
<action
attribute="someForm"
name="someForm"
path="/my/path"
scope="request"
validate="false"
parameter="cmd"
type="someAction">
<forward
name="showForm"
path="myTileDefinition"/>
</action>
If I click the link to /my/path.do my action class sends out the
showForm then displays myTileDef. Then it executes the same action class
again. The second execution doesn't copy some of the information from
the first execution. My action class is a LookupDispatchAction so on the
second time it errors out because cmd is not defined as a parameter. If
I point my action at a regular jsp page with a tile definition in the
page it does the same thing. If I point the action at a plain old jsp
page it executes once. Why does this execute more then once? how do I
write code around this problem? I'm using struts 1.2.7. Thanks!

Fount the problem. I had <img src="" /> in my tile. When I removed it it
worked. Not sure why that causes problems. That didn't have anything to
do with the link I was clicking. thanks

I think this has me on the right track. I was using firefox. I tried
this with ie and it works fine. I'm clicking on a link that is an
<html:link> to cause this. If I type the url the same thing happens.
There is javascript code that submits the page by clicking on a link
but it's not tied to the link I am clicking. there are some links where
href=# but they are not created by struts tags. How does src="#" trigger
another submit? I'm going to start taking html out of the page till I
figure out which piece causes this. I post back if I find anything
interesting. Thanks!

How are you invoking the action (from an HTML link? form submission?
directly by typing the URL into the address bar?); is there any Javascript
involved?
Does the response contain any suspect hrefs (for example <img/> tags with
src="#") that might be triggering the second request?
Using something like tcpflow to watch what's going over the wire can help
figure out where your 'mystery' request is coming from.
If that doesn't help, I'd suggest posting any HTML that invokes the action
as well as the HTML it produces as a resonse.
