Hi Yesterday I rebuilt my image using the latest Metacello ConfigurationOfSeaside30 (loadLatestVersion) and the latest code in Pier2 and Magritte2 repositories. I've noticed a new problem when I attempt to add a component using the Pier web ui which results in a form validation error: 'Component Class: Invalid input given' To reproduce: * download latest build from: http://hudson.lukas-renggli.ch/job/Seaside%203.0/ <http://hudson.lukas-renggli.ch/job/Seaside%203.0/>* open and start web server * open a workspace and execute: PRPierFrame registerAsApplication: 'pier' kernel: (PRKernel named: 'defaultKernel'). * browse to http://localhost:8080/pier and select the edit link * type: '+acomponent+' into the text in the box and press 'save' * click on the 'acomponent' link and in the type select list choose 'Component' and press 'Add' * select any class from the 'Component Class' select list and press 'save' * note the form validation error: "Component Class: Invalid input given" Investigation: * MAKindError is being generated as the component selected is always WAComponent regardless of the user selection. * WAComponent is the default value ; the selected value is not being set as the callback in MASelectListComponent>>renderOption:on: is never called. This appears to be a Seaside bug; it appears that the callbacks for a grouped select list are not called on form submission. Further investigation: * using the latest build browse to http://localhost:8080/magritte/editor * select a type other than 'Boolean' from the grouped select box eg choose 'File' and press Add * notice that whatever type you choose 'Boolean' is always selected. * place a 'self halt' in the callback in MASelectListComponent>>renderOption:on: and notice that it is never called. I noticed that there have been bug fixes on the select tag: http://lists.squeakfoundation.org/pipermail/seaside/2010-January/022358.html I made sure that the build I was using had the latest Seaside-Canvas (Seaside-Canvas-lr.88.mcz). My previous image with working grouped selection list was based on Seaside-Canvas-pmm.74.mcz Hope I'm not reporting something that has already been fixed or noticed elsewhere Nick
