[xwiki-users] Migration away from TikiWiki - Forms based question.
by HadleysHope 20 Oct '15

20 Oct '15

I wonder if anyone can help. I started using xwiki but have been a long time use user of tikiwiki. In it there is something called "trackers" these are basically forms. So I can create trackers that people can fill out and even forms that reference other forms. So for instance I might have a tracker called regions that might have two fields, State and City. So I fill out a bunch of those for different states. Then I can use this in another tracker so that when I select a state, a list of cities relevant to that state entered in the previous tracker will auto populate a drop down. My question is, firstly, how do you create these forms (I looked at create app and it doesn't seem to do what i want it to) and secondly how do you reference other forms? Any help greatly appreciated.

[xwiki-users] "XWiki is initializing" message
by Debajit Adhikary 17 Oct '15

17 Oct '15

I am in the process of writing an extension for XWiki. Each time I make some code changes, and then refresh my local instance of XWiki I see the message "XWiki is initializing..." which takes some time to finish. For small code changes, I feel like this "initialization" step slows down my development. What exactly is happening in this "XWiki is initializing..." step, and what could I do to avoid this step entirely, so that I can work faster on my extension?

[xwiki-users] Double parents after upgrading to 7.2
by Silviu Vulcan 16 Oct '15

16 Oct '15

Hi, I am building a xwiki site and recently upgraded to 7.2 (we are holding off launch for the permissions inheritance and nesting features) The site was built using spaces as parents for pages and child-parent relations. After upgrade I realized two issues: 1. In the document tree the parrents are doubled. Example at: http://imgur.com/Jj72P17l.png 2. Trying to edit the parent of a page (Rename->network icon) brings up a list with a dark overlay that never goes away and I cannot click anywhere. Any ideas what am I doing wrong? Cheers, Silviu

[xwiki-users] Ldap Group config question
by Gary Lloyd 16 Oct '15

16 Oct '15

Hi, Im brand new to XWiki and am slowly working my way through things. Im using ver 7.2 enterprise. I have managed to configure ldap for active directory so that I can get a single user to login, but how do I get XWiki to recognise a user group? Ive seen various things online but nothing seems to work for me. Its probably a simple configuration issue but im missing it. Im using the ldap admin extension, so am not directly altering the xwiki.cfg Any help is greatly appreciated. Im so close!! /Gary./

[xwiki-users] Making an HTTP POST call from an XWiki extension
by Debajit Adhikary 15 Oct '15

What is the easiest/recommended way to make an HTTP POST or GET call from within an XWiki extension? Should I use Restlet? (I am guessing XWiki comes with Restlet support)

[xwiki-users] ScriptService issue --- Cannot access @Named ScriptService object through $services object
by Debajit Adhikary 15 Oct '15

15 Oct '15

I created an XWiki component which is available as a jar file. I have a ScriptService class for the component too: ---- @Role public interface SearchClient { String search(); } ---- @Component @Singleton public class InternalSearchClient implements SearchClient { public String search() { return "test search results"; } } ---- @Component @Named("internalSearch") @Singleton public class InternalSearchScriptService implements ScriptService { @Inject private InternalSearchClient searchClient; public String search() { return this.searchClient.search(); } } ---- I've added all the above files into their own jar with a components.txt file: com.mycompany.wiki.search.InternalSearchClient com.mycompany.wiki.search.InternalSearchScriptService and in my Wiki's pom.xml, I have the following: <dependency> <groupId>org.xwiki.commons</groupId> <artifactId>xwiki-commons-script</artifactId> <version>${commons.version}</version> </dependency> Now from my Wiki page, when I do the following: {{groovy}} println(services.internalSearch.search()) {{/groovy}} I get an error message saying "java.lang.NullPointerException: Cannot invoke method search() on null object" What am I doing wrong here? (I followed the directions in http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents — have these directions changed, and/or is there anything else I need to do? )
