[xwiki-devs] Boston and/or New York Meetup this week
by Ludovic Dubost 12 May '08

12 May '08

Hello XWiki users and developers, I'm in Boston today and tomorrow and could be available for a quick meetup with users of XWiki if there are some in the area. I will also be in New York wednesday to saturday. Anybody interested in an informal Meetup ? I would love to hear what we could improve in XWiki and show the latest things we are working on.

[xwiki-devs] Hashmap vs. Objects (theoretical question about a data model)
by Kamna Jain 11 May '08

11 May '08

Hi All, This question "might" be related to the thread that has been active in the past couple of days about the data model. We have a similar situation with the only difference being that we want to create lists or collections (like Groups) of certain pre- created Objects. The Object as a whole may/will belong to more than one such collection - which means that if we were to use a Document to link a Collection and its contents, then every document will have a COPY of the same object and this is definitely not desirable for good performance - Right? So, in that case, we have 2 alternatives: 1) Use the techiniques used in XWiki to create Groups: each group has objects of class XWikiGroup with just one field that refers to the Member name. OR 2) Use XWiki.getHashmap() and add the Collection and its members to the hashmap (as the Key and Value resp.) The XWiki API indicates that the option #2 must be used in xwiki when Objects can not be created. My Question is: -> Even though I could use option #1 and create objects and add them to the document that would represent the Collection, can I still use option #2 because I think that it will provide better performance. Am I right in my assumption? What should I do? Thanks a lot for all help!

[xwiki-devs] reading a single property
by [Ricardo Rodriguez] Your EPEC Network ICT Team 11 May '08

11 May '08

Hi, Sorry if this question is too basic, but I am not able to find the answer. I am able to read all the properties of an instance of Species.SpeciesClass class in a document with this code: #set($obj = $doc.getObject("Species.SpeciesClass").xWikiClass) #foreach($prop in $obj.properties) *${prop.prettyName}:* $doc.display($prop.getName())<br/> #end But, please, how could I read a single, let's say, Genrus property of this object? Thanks! Ricardo -- Ricardo Rodríguez Your EPEC Network ICT Team

[xwiki-devs] Deprecation checks
by Sergiu Dumitriu 10 May '08

10 May '08

Hi devs, This week I introduced the support for chainable uberspectors, and beside the SecureUberspector that was used before, now there's also a DeprecatedCheckUberspector, that prints a warning in the logs whenever a deprecated method is called from velocity. Several things I'd like to emphasize: - These logs break the validity check done in the XmlRpc tests, so this allows us to detect (almost) any usage of the deprecated methods in wiki documents and update these documents - It also means that we can't make a product release while there are deprecated calls in the wiki pages - "deprecated" means "having the @Deprecated annotation". There's no (simple) way of checking for the @deprecated doclet. - whenever something gets deprecated, be sure to add this annotation, as otherwise the calls to the deprecated method won't be detected - could someone help with cleaning the wiki source in order to fix the builds on the 1.5-depending products? Just look at the continuum build results (for example http://continuum.xwiki.org/continuum/buildResult.action?buildId=20015&proje…) and look for messages like: [WARNING] Deprecated usage of method [com.xpn.xwiki.api.XWiki.parseInt] in Main.Dashboard@14,25 and update the affected document (could be a GSoC student...) - the logged document name is not always right, as it doesn't reflect inclusions and calls to $xwiki.parseText -- Sergiu Dumitriu http://purl.org/net/sergiu/
