seaside 3.0 pier image loading problem

When I merged the latest Pier code with the Pier for Seaside 3.0 branch I noticed that the Pier logo wasn't appearing on the initial screen, although it appeared on the 3.0 branch prior to the merge. I traced the difference in behaviour down to a code change in PRViewCommand>>initialRequest the pre-merge version: initialRequest: aRequest | viewClass | super initialRequest: aRequest. viewClass := PRPierFrame classFromRequest: aRequest name: 'view' base: PRViewComponent. (viewClass isNil and: [ self structure isFile ]) ifTrue: [ viewClass := PRDownloadView ]. (viewClass notNil and: [ viewClass isValidIn: self context ]) ifTrue: [ self viewComponentClass: viewClass ]. self viewComponent visiblePresentersDo: [ :each | each initialRequest: aRequest ]. (self viewComponent isFullResponse) ifTrue: [ self viewComponent handle: WACurrentRequestContext value ] post-merge version: initialRequest: aRequest | viewClass | super initialRequest: aRequest. viewClass := PRPierFrame classFromRequest: aRequest name: 'view' base: PRViewComponent. (viewClass notNil and: [ viewClass isValidIn: self context ]) ifTrue: [ self viewComponentClass: viewClass ]. self viewComponent visiblePresentersDo: [ :each | each initialRequest: aRequest ]. (self viewComponent isFullResponse) ifTrue: [ self viewComponent handle: WACurrentRequestContext value ] the pre-merge version has the addition of the code: (viewClass isNil and: [ self structure isFile ]) ifTrue: [ viewClass := PRDownloadView ]. However this code isn't present in the main 2.8 code-base. The problem is more subtle. The pier environment stylesheet requests an image from: '/seaside/pier/environment/pier.png?view=PRDownloadView' this is trapped by the code in WAOldPathComptibilityRequestHandler which issues a 301 moved permanently redirect to '/pier/environment/pier.png'. The problem is that during the redirection the url parameters have been lost. I've fixed the problem locally by changing WAOldPathComptibilityRequestHandler>>handleFiltered: from: handleFiltered: aRequestContext | url | url := aRequestContext request url copy. url path removeFirst. aRequestContext response movedPermanently; location: url. aRequestContext respond to: handleFiltered: aRequestContext | url | url := aRequestContext request url copy. url path removeFirst. url parameters: aRequestContext request fields. aRequestContext response movedPermanently; location: url. aRequestContext respond I copy the parameters from the request to the url. Should I save this change into seaside 3.0 repositories? Or is there something else that needs fixing higher up the call stack to account for why the parameters haven't been added to the WAUrl object? Hope this all makes sense Nick
