issue with the evolution matrix
by Franco Sabadini 17 Jan '12

17 Jan '12

Hi, I've started working with Moose with a friend and we have used Kumpel to create a model from a SVN repository and we encountered an issue when trying to create the evolution matrix. Can u help us? One of the models we created is from the svn repository svn://svn.jdownloader.org/jdownloader <about:blank> without user or password. The error we r getting when trying to create the evolution matrix is: VM: unix - i686 - linux-gnu - Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.78] Image: Pharo1.3 [Latest update: #13315] UndefinedObject(Object)>>doesNotUnderstand: #versions Receiver: nil Arguments and temporary variables: aMessage: versions exception: MessageNotUnderstood: receiver of "versions" is nil resumeValue: nil Receiver's instance variables: nil KMPProjectHistory(HismoAbstractHistory)>>completeHistoryCollect:ifNotPresent: Receiver: svn://svn.jdownloader.org/jdownloader (10) Arguments and temporary variables: aBlock: [:each | each] anotherBlock: [:eachRefVersion | eachRefVersion] data: an OrderedCollection() Receiver's instance variables: mooseID: 287595 state: a MooseDefaultState versions: an OrderedCollection(1@nil +1090, -0 2@astaldo +6, -8 3@astaldo +457,...etc... referenceHistory: nil parentHistory: svn://svn.jdownloader.org/jdownloader (10) name: 'svn://svn.jdownloader.org/jdownloader' authors: an OrderedCollection(a KMPAuthor #astaldo a KMPAuthor #coalado) rootHistory: D (1) builder: a KMPProjectBuilder [aView nodes: (self completeHistoryCollect: [:each | each] ifNotPresent: [:eachRefVersion | eachRefVersion]) using: (MORectangleShape new withoutBorder; fillColor: [:each | each == each referenceVersion ifTrue: [Color lightGray] ifFalse: [Color white]])] in KMPProjectHistory(HismoAbstractHistory)>>viewSimpleEvolutionMatrixIn: Receiver: svn://svn.jdownloader.org/jdownloader (10) Arguments and temporary variables: aView: a MOViewRenderer Receiver's instance variables: mooseID: 287595 state: a MooseDefaultState versions: an OrderedCollection(1@nil +1090, -0 2@astaldo +6, -8 3@astaldo +457,...etc... referenceHistory: nil parentHistory: svn://svn.jdownloader.org/jdownloader (10) name: 'svn://svn.jdownloader.org/jdownloader' authors: an OrderedCollection(a KMPAuthor #astaldo a KMPAuthor #coalado) rootHistory: D (1) builder: a KMPProjectBuilder [:each | aZeroArgBlock value] in MOViewRenderer>>node:using:forIt: Receiver: a MOViewRenderer Arguments and temporary variables: aZeroArgBlock: svn://svn.jdownloader.org/jdownloader (10) each: [aView nodes: (self completeHistoryCollect: [:each | each] ifNo...etc...

Glamour: actions should be rendered by a double dispatch
by Esteban Lorenzano 17 Jan '12

17 Jan '12

Hi Doru, list I think that actions (those in the toolbar) should be rendered by a double dispatch mechanism... I want to be able to render different kind of things as an action (for instance, a multistate button). What do you think? best, Esteban

Problems to run Kumpel
by Felipe González 13 Jan '12

13 Jan '12

Hi, I've been trying to run Kumpel on my computer the last few days following the instructions here: http://www.moosetechnology.org/tools/kumpel But i got nothing so far, even when i left my computer a couple of hours doing the following: KMPProject new projectName: 'verveinej'; startRev: '1'; endRev:'2'; url: 'svn://scmscm.gforge.inria.fr/svn/verveinej/'; buildDiffs: true; load On my terminal i got this: /usr/bin/zenity Building Project verveinej main Step 1: Loading Project Info... Step 2: Loading Initial List of Directory Tree... Step 3/4: Loading Logs... Step 4/4: Loading File Diffs... Initial Diff Path=svn://scm.gforge.inria.fr/svn/verveinej Thread 1 : Loading Diff 2 took miliseconds to load diffs: 15237 and then i got stuck. Any suggestions? am i doing something wrong?

[ANN] [Release] Neptuno, the DBXBrowser
by Guillermo Polito 11 Jan '12

11 Jan '12

Hi! We are glad to announce the first stable release of the DBXBrowser, named Neptuno, the last piece in the DBXTalk tools project sponsored by ESUG. *What is this browser?* It is a Glamour based browser which works as a GUI to work with OpenDBX connections. * How does it look like?* I attach a screenshot with a brief look :) *Which databases does it work with?* It is currently working with OpenDBX connectors for: - mysql - postgresql - oracle - sqlite * How should I download it?* I'd like to link to the site here, but it's currently down (and we are working for your happiness :D ), so: Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfDBXBrowser'; load. (((Smalltalk at: #ConfigurationOfDBXTools) perform: #project) perform: #version: with: #stable) load: 'Neptuno' *How should I contact the DBXTalk team for feedback, bug reports, questions, or whatever?* The project's mailing list: dbxtalk(a)googlegroups.com The project's issue tracker: http://code.google.com/p/dbxtalk/issues The (currently down) site, with docs and stuff: http://dbxtalk.smallworks.com.ar/ Thanks!

dynamic sub browser gets not rendered :/
by Guillermo Polito 10 Jan '12

10 Jan '12

Hi! I have a browser where I do something like: browser transmit to: #somePane; andShow: [ :a | a dynamic presentation: [ :some :element | some custom: element buildCustomBrowser ] ] And then, I have implemented #buildCustomBrowser for example as: buildCustomBrowser | browser | browser := GLMTabulator new. browser row: #tables. browser transmit to: #tables; andShow: [ :a | a table title: ('Columns for {1}' format: { table name }); addColumn: (GLMTableColumn new title: 'Column name'; computation: #name); addColumn: (GLMTableColumn new title: 'Null'; computation: [ :column | column nullable asString ]); addColumn: (GLMTableColumn new title: 'Type'; computation: [ :column | column typeName asString ]); addColumn: (GLMTableColumn new title: 'Length'; computation: [ :column | column length asString ]); addColumn: (GLMTableColumn new title: 'Primary Key'; computation: [ :column | column isPrimaryKey asString ]); display: self columns; yourself. ]. ^browser And It does not render the table :(. If I change it to something like: buildCustomBrowser | browser | browser := GLMTablePresentation new. browser title: ('Columns for {1}' format: { table name }); addColumn: (GLMTableColumn new title: 'Column name'; computation: #name); addColumn: (GLMTableColumn new title: 'Null'; computation: [ :column | column nullable asString ]); addColumn: (GLMTableColumn new title: 'Type'; computation: [ :column | column typeName asString ]); addColumn: (GLMTableColumn new title: 'Length'; computation: [ :column | column length asString ]); addColumn: (GLMTableColumn new title: 'Primary Key'; computation: [ :column | column isPrimaryKey asString ]); display: self columns. ^browser It works, but I can't have several presentations for the same object... :( I tried debugging the code, but I get lost and lost a lot of time without figuring anything :(. Is there a way to do this? any workaround? or is it a bug or it is ignorance from my side? Thanks! Guille

For me, it should work without modification....The following method that you are using should carry out the desired functionality... LinearFillColor: #counts within: rules; LinearFillColor: part should take as a parameter the count of a single rule. The within: part should take an array that contains all the counts of all your rules in the system...
