RE: image submit and lookupDispatchAction - drives me struts
Well, yes, you could say: Look for anything in the request that matches a pattern. Then it has to iterate through all request parameters and execute the matching algorithm on each parameter. By defining a list of names to expect, then I'm performing a hash key lookup on each element in a very small list. robert -Original Message- From: Axel Groß [mailto:[EMAIL PROTECTED] Sent: Thursday, July 01, 2004 4:40 AM To: Struts Users Mailing List Subject: Re: image submit and lookupDispatchAction - drives me struts hi robert! that's really nicely written code. I'm not completely sure, why it does what i think it does though: you limit, which methods should get called in the struts-config, right? (by specifying a list of the allowed buttonnames in the mapping) then you check if there is a [buttonname].x in the request which fits, right? this indicates the button [buttonname] has been pressed so you dispatch to lookup with [buttonname] as lookup key so what is the intention for limiting the methods to the specified set? if i change it to ignore the dynamic part of the button name it should work for me; i should add some regexp lookup, maybe :) thanks, axel On 2004-06-28 at 12:00:22 -0400, Robert Taylor wrote: This may help: http://issues.apache.org/bugzilla/show_bug.cgi?id=19925 robert -Original Message- From: Axel Groß [mailto:[EMAIL PROTECTED] Sent: Monday, June 28, 2004 11:52 AM To: Struts Users Mailing List Subject: Re: image submit and lookupDispatchAction - drives me struts Hi Wendy thanks for the reply and the link!

image submit and lookupDispatchAction - drives me struts
hi there!
i wanted to use images to hide my ugly submit button names, but exchanging
html:submit with html:image doesn't work;
this is what is rendered:
html:submit property=action
fmt:message key=profiles_action_${ownerName}_${prepopulatedActionPart}/
/html:submitbr/
html:image src=images/edit-button.jpg property=action
fmt:message key=profiles_action_${ownerName}_${prepopulatedActionPart}/
/html:imagebr/
bean:define id=editButton type=java.lang.Stringfmt:message
key=profiles_action_${ownerName}_${prepopulatedActionPart}//bean:define
html:submit property=action value=${editButton}/br/
html:image src=images/edit-button.jpg property=action value=${editButton}/
gets rendered to
input type=submit name=action value=EDIT_USER /br/
input type=image name=action src=images/edit-button.jpg /
input type=submit name=action value=EDIT_USER /br/
input type=image name=action src=images/edit-button.jpg value=EDIT_USER /
so the html:submit buttons do work, but neither of the html:image buttons
pass the parameter on and i get a null reference for
request.getParameter(parameter);
(with parameter.equals(action))
the resulting error message is:
Request[/action/lookupDispatch] does not contain handler parameter named action
anybody knows what could help?
thanks,
axel
