[xwiki-devs] question about class with property DBList of objects
by Pascal Voitot 25 Sep '08

25 Sep '08

Hello, I want to create a class with a DBList property not containing strings but a list of ID to other BaseObjects... Then from velocity I want to access directly to this list of objects to display each object one by one. But for this, you need ProgrammingRights because api.Object.get(propertyname) returns a display of the list and not the list... to retrieve the list, you must call getXWikiObject which requires programming rights... But I don't want to give programming rights just to view objects! Moreover I don't want to be forced to go among $doc.searchXXX just to find my objects because I have already these objects in my list... Do you a solution for me? my model might be bad also...

[xwiki-devs] small bug in com.xpn.xwiki.api.Document
by Pascal Voitot 24 Sep '08

24 Sep '08

I have certainly found a small bug in com.xpn.xwiki.api.Document, there is: /** * Select a subset of objects from a given class, filtered on a "key = value" criteria. * * @param classname The type of objects to return. * @param key The name of the property used for filtering. * @param value The required value. * @return A Vector of {@link Object objects} matching the criteria. If no objects are found, or * if the key is an empty String, then an empty vector is returned. */ public Vector<Object> getObjects(String classname, String key, String value) { Vector<Object> result = new Vector<Object>(); if (StringUtils.isBlank(key) || value == null) { return getObjects(classname); } try { Vector<BaseObject> allObjects = doc.getObjects(classname); if (allObjects == null || allObjects.size() == 0) { return result; } else { for (BaseObject obj : allObjects) { if (obj != null) { BaseProperty prop = (BaseProperty) obj.get(key); if (prop == null || prop.getValue() == null) { continue; } if (value.equals(prop.getValue())) { result.add(newObjectApi(obj, getXWikiContext())); } } } } } catch (Exception e) { } return result; } What is not good: if (value.equals(prop.getValue())) { result.add(newObjectApi(obj, getXWikiContext())); } in XWikiDocument.getObject(), it is: if (value.equals(obj.getStringValue(key))) { return obj; } so getObjects only works when the property is a String.

[xwiki-devs] [GWT WYSIWYG] Character map issue - Need help for solution
by Vincent Massol 24 Sep '08

24 Sep '08

Hi, We have a problem with the GWT character map. It contains some characters that are not ISO-8859-1. The problem is that since our default encoding is ISO-8859-1 (<?xml version="1.0" encoding="ISO-8859-1" ?>) the browser replaces for example this character ∞ with ∞ Our rendering doesn't accept HTML so this value is escaped and is shown as is. So we have several non-satisfactory options: 1) Switch to UTF8 by default. A good thing but that won't solve the problem for those using the GWT editor in ISO-8859-1 encoding. 2) Modify the GWT editor character map so that it only shows characters valid with the current encoding. This is a pity since it should be possible to display other chars since the browser knows how to display them even though the user is not in the correct encoding 3) Introduce a wiki syntax for representing characters not allowed in the current encoding. However this means we'll still need to replace ∞ with this syntax before the rendering is called and this forbids users to enter ∞ in the wiki editor so this is not good. Any better idea? WDYT? Thanks -Vincent

[xwiki-devs] Help find proper place for a code snippet :)
by Asiri Rathnayake 24 Sep '08

24 Sep '08

Hi Devs, I'm working on integrating webdav into XWiki UI (+FoXWiki) and I kind of ran into a small problem. Our current xwiki-webdav-foxwiki test server is at http://91.121.237.216/xwiki/bin/view/Main/ (you may give this a try with firefox). Here in the attachments view, if a firefox user clicks on the "Edit" link, it should first check if the user has foxwiki installed and if not should trigger an installation. If the user has foxwiki installed, foxwiki will take care of the rest of tasks. The problem is, foxwiki install trigger code is something like this : <code> var params = { "FoXWiki": { URL: " http://91.121.237.216/xwiki/bin/download/Main/WebHome/foxwiki.xpi", IconURL: " http://91.121.237.216/xwiki/bin/download/Main/WebHome/foxwiki.png", Hash: "sha1:76920ec6392fec911e13b53ed8d23f64d75502c6", toString: function () { return this.URL; } } }; InstallTrigger.install(params); </code> Currently i have put this code into /skins/albatross/scripts/webdav.js This doesn't look right for obvious reasons, but where else would i put this code ? Please help me out :) Thanks. - Asiri

[xwiki-devs] Link between 2 XWiki objects using BaseObject ID
by Pascal Voitot 24 Sep '08

24 Sep '08

Hello, I want to do the following: I create a class with one LongProperty field containing a long ID of another BaseObject. The idea is to link an object to another object by simply using its hashcode ID and not the whole docname+classname+nb string. A one-to-one association if you prefer. $xwiki.search("from BaseObject as obj...") will return a BaseObject so I can get the ID here. But in velocity, I access objects using $doc.getObject() which returns a Object API. I can't find any simple way to retrieve the ID of the nested BaseObject from Object API because getBaseObject requires programming rights. Do you have an idea for me? Is it mandatory to use the docname+classname+nb string to identify an object from velocity? regards Pascal

[xwiki-devs] [Reminder] How to best answer questions on the list
by Vincent Massol 23 Sep '08

23 Sep '08

In order to be as efficient as possible in answering questions and so that the answer benefit others the most we had defined a strategy. It's written on http://dev.xwiki.org/xwiki/bin/view/Community/Contributing#HStrategiesforan… Here's the relevant excerpt: " 1.1 Strategies for answering on the XWiki lists Here's a good strategy that improves the XWiki documentation on xwiki.org: 1. someone (A) asks a question on a xwiki list 1. someone (B) knows the answer 1. B verifies that the answer can be found on xwiki.org and if so gives a link to it in the reply to A 1. If the answer is not found on xwiki.org, then B adds it (*) and then gives a link to it in the reply to A In this manner we all enrich the xwiki documentation and it'll only take marginally longer to answer questions. The next time someone asks the question again we can simply point him/her to the location on xwiki.org What happens otherwise is that usually people answer in the email, often giving very long and elaborate answers with lots of knowledge/ wisdom in it. Then another person comes in, asks the same question and we answer again, etc. The result is: * the xwiki.org documentation is not better * overall as a team we are less efficient (*) One difficult in putting the answer on xwiki.org is to find the right location where to put it. So here are a few tips: * For code snippets, add it to the [Code Zone>code:Main.WebHome] * For questions on how to use XWiki, please add it to the [Features guide>platform:Features.WebHome] * For development questions, add it to the [Developer's guide>platform:DevGuide.WebHome] * For configuration questions and administration questions, add it to the [Administration guide>platform:AdminGuide.WebHome] * For other questions, add them to the [FAQ>xwiki:FAQ.WebHome] " I've seen a lot of emails recently where we're not doing this (me included) and thus I thought it would be to remind us all about strategy. Also xwiki.org hasn't been improved a lot for a while so it's good to make an effort to do so. Could be a good thing to do especially during the bug fixing week. WDYT? Thanks -Vincent

Hi guys, We're getting behind again in term of bug closings vs bug openings, see http://tinyurl.com/52oxjq I think we'll need to start again the Bug Fixing Day. I propose to start it again next week. WDYT? Any better idea? Thanks -Vincent

[xwiki-devs] XE 1.6RC1 release date changes
by Vincent Massol 22 Sep '08

22 Sep '08

Hi, We're having some last-minute problems with the new GWT editor and we need a few more days to fix them. Thus I'm proposing that we delay the XE 1.5RC1 release for 3 more days to Thursday 25th of Sept. This means a potential 1.6 Final (if no important bugs are found) for the 29th of Sept. Thanks -Vincent
