Re: [xwiki-users] Get parts of a page...
I tied to replace getDocument() in this line with getTranslatedDocument()...
#foreach($ParagraphBlock in
$topicDefenitionDocument.getDocument().getXDOM().getBlocks("class:ParagraphBlock",
"DESCENDANT"))
But the $ParagraphBlock is empty???

In document API you have getTranslatedDocument() which return the
right document from current locale point of view on which you can then
call getXDOM().

Re: [xwiki-users] Clustering of Xwiki
There is no system like this by default. You could probably empty all the caches in some script every minutes but note that doing something like this would cause big performances issues especially on document loading. Emptying a cache every minutes is not very different from not having cache at all. On Thu, Jun 11, 2015 at 4:00 PM, Enste, Patrick wrote: > Great!

Re: [xwiki-users] Get parts of a page...
I almost have it right I think:
#foreach($topicDefenitionDoc in $topicDefenitionDocs)
#set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
#set($topicDefenitionObject=$topicDefenitionDocument.getObject($classDefenitionName))
==
$topicDefenitionDocument.display('topicTitle','view',$topicDefenitionObject) ==
##$topicDefenitionDocument.display('topicDescription','view',$topicDefenitionObject)
#foreach($ParagraphBlock in
$topicDefenitionDocument.getDocument().getXDOM().getBlocks("class:ParagraphBlock",
"DESCENDANT"))
#if($velocityCount == 1)
#set ($blockParent = $ParagraphBlock.getParent())
#set ($leadParagraph = $services.rendering.render($ParagraphBlock,
"xwiki/2.1"))
#if($blockParent.getParameter('class') == 'lead')
(%class="lead"%)((($leadParagraph)))
#else
$leadParagraph
#end
#end
#end
The one issue I have left is the translation.
The $topicDefenitionsDocs are in the $context.language
But the Blocks are in the default language?
How can I get the blocks in the $context.language

There is no such method in Block so not sure what you expect "self" to
do. If you want to render a block you can use rendering service, see

Exacly.

There is no such method in Block so not sure what you expect "self" to
do.
I read something in this page which reminds me of my days in XSLT...
http://nexus.xwiki.org/nexus/service/local/repositories/releases/archive/org/xwiki/rendering/xwiki-rendering-api/6.4.4/xwiki-rendering-api-6.4.4-javadoc.jar/!/org/xwiki/rendering/block/Block.Axes.html
Self is mentioned as last search option...
If you want to render a block you can use rendering service, see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Rendering+Module.
OK

Not exactly, it's not so much about synchronizing cache. As the property suggest what happen is that some events like modified documents go trough the cluster using JGroups and they are injected in the local event manager of other members to let all listeners know a document has been modified and do whatever they want about it (invalidate some entry from a cache because it depend on the modified document, update some local solr/lucene index, etc.). > > Now we want to use the following architecture: > > We have 2 datacenters.

I don't really know Oracle RAC but if what you mean is that you have two groups of instance and each group have a different database as lon have you have some mecanisme that make sure those database are synchronized it should be ok too. You put everyone in the same cluster and documents related caches will be invalidated everywhere when you modifiy a document for example. > > We would have 1 loadbalancer to manage the load between the two datacenters > and 1 loadbalancer in every datacenter to manage the load between the 2 > instances.

[xwiki-users] Clustering of Xwiki
Hey everybody, I found some information on clustering for Xwiki where I have to set the observation.remote.enabled to true. Per my understanding the cache would be synchronized between every instance (via Jgroups). Now we want to use the following architecture: We have 2 datacenters. In each datacenter are 2 servers with a Xwiki instance running (so 4 instances in 2 datacenters). As database we want to use Oracle RAC. Is it possible to run these 4 instances on the Oracle RAC? Is it possible to invalidate the cache of another instance if one instance has some write action or something (so it generates a new cache on its own)? We would have 1 loadbalancer to manage the load between the two datacenters and 1 loadbalancer in every datacenter to manage the load between the 2 instances. Every instance should show the same content... Kind regards, Patrick ___ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
Re: [xwiki-users] Get parts of a page...
A little progress, but what to do to inspect if paragraph has class lead to it
and to display the paragraph remains unclear.
#foreach($topicDefenitionDoc in $topicDefenitionDocs)
#set($topicDefenitionDocument=$xwiki.getDocument($topicDefenitionDoc))
#set($topicDefenitionObject=$topicDefenitionDocument.getObject($classDefenitionName))
==
$topicDefenitionDocument.display('topicTitle','view',$topicDefenitionObject) ==
$topicDefenitionDocument.display('topicDescription','view',$topicDefenitionObject)
#foreach($ParagraphBlock in
$topicDefenitionDocument.getDocument().getXDOM().getBlocks("class:ParagraphBlock",
"DESCENDANT"))
#if($velocityCount == 1)
$ParagraphBlock.self
#end
$velocityCount
#end
#end
#else
Will give me a correct count of all html parts
One of these, usually the first is enclosed by a
I would like to display this text only
$ParagraphBlock.self
But it does only show:
$ParagraphBlock.self
as if method in this context is not valid
Second I have no idea how to inspect the that holds the
first
My output currently looks as follows:
Behavior
Behavioral problems in people with CdLS are not inevitable. In fact, some
people have no behavioral problems, while others are mild, have transient
problems. Many problems are treatable. At the same time it is obviously the
severity of behavioral problems in people who injure themselves or others deny.
Many behavior problems are a reaction to something in the body or the
environment and they are cyclical (they come and go). Behavioral changes often
occur in early childhood and the teenage years. Like most people, develop
people with CdLS behavior for a certain reason, and it is important to first
address the underlying causes of the behavior. If the source of the behavior is
determined, one can try to recognize that resource and to avoid.
If the behavior follows a pattern (such as it is always at the same time, same
place, or to a particular person) treatment will begin to investigate whether
the situation can be changed. When the problem is that the environment does not
provide sufficient structure or variation, that can be addressed. Discovering
the reasons for behavior is the most difficult part of the treatment. Sometimes
one can not eliminate the cause and one should look for ways to control the
behavior. This can vary from moment to rest in your own room, distract the
person to another activity to the use of protective clothing.
It remains important to always look at possible underlying medical problems.
Gastrointestinal problems, muscle pain, ear infections, dental pain and
epilepsy can cause irritability, self-injurious behavior or aggressive
behavior. Even people who can communicate well, sometimes can not recognize the
source of their discontent. Undetected disease (silent reflux) and tooth decay
/ gum disease are the two most common causes of behavioral changes.
