In this post you can find a summary of the results, with some interesting ideas on things to implement in the future: http://www.xwiki.org/xwiki/bin/view/Blog/ProductSatisfactionSurvey2015Resul… Now XWiki developers can look at the list when deciding/discussing what features/items to implement in 8.x and beyond. In a year or so we could do a postmortem to see what has been implemented. Thanks, Silvia

[xwiki-users] Export to PDF java.lang.NullPointerException on some pages (possibly if images are too big)

by Denis.Germain＠isocel.info

When trying to export PDF some (not all) page of my XWiki 7.2, I get an error in the log and the PDF is never generated. HTML export works fine. Here are the first lines from the error : Dec 2 09:37:07 xwiki01 server: java.lang.NullPointerException: Parameter alpha must not be null Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.AlphaRasterImage.<init>(AlphaRasterImage.java:57) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.AlphaRasterImage.<init>(AlphaRasterImage.java:71) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.render.pdf.ImageRenderedAdapter.setup(ImageRenderedAdapter.java:127) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.pdf.PDFDocument.addImage(PDFDocument.java:816) ~[fop-1.1.jar:na] Dec 2 09:37:07 xwiki01 server: at org.apache.fop.render.pdf.AbstractPDFImageHandler.handleImage(AbstractPDFImageHandler.java:46) ~[fop-1.1.jar:na] I can't say for sure that the size of the images in those pages is the cause of the export failure, but just before the stacktrace, I get a few WARN Dec 2 09:37:06 xwiki01 server: 2015-12-02 09:37:06,773 [ http://xwiki01:8080/xwiki/bin/export/White_Rabbit/Fabrication/GitLab+-+Manu… ] WARN o.a.f.a.FOUserAgent - Line 1 of a paragraph overflows the available area by 9000 millipoints.

[xwiki-users] Request: make linking easy

by Anton Hughes

HI all One of the key concepts of a wiki is its easy for everyone to edit. There are various wiki syntaxs - perhaps the most popular being Mediawiki - and all of them have a goal of making it easy for users to write in the specific syntax, without the need to know html. So, one of the most basic features of a wiki, CMS, and the web, is linking. In Html a user has to write - a - href - the user has to know if it is relative or absolute - link text Its not a lot, but its still too much for non technical people. In a normal wiki a user just writes [[MyExamplePage]] This is so simple that anyone can do it! In XWiki (and I found this out by using the wysiwyg editor) [[MyExamplePage>>doc:MyExamplePage.WebHome]] What is doc? And WebHome? And >>? And whats with the dots, semi colons? As a technical person I can probably figure this out. But there is no way I could sell my management on this. Non technical people will never understand this. And yes, non-tech people can use the wysiwyg. But then why use a wiki? Why not just use a CMS. The -- Anton Hughes
