jsf 2 - Why does the ajax event not fire? -

-

I got a prefix tree in my application. I tried to load all the data once, which is equivalent to 2500 objects It is, only a few are used. So I tried to apply some sort of lazy loading, the first level is loaded and I want to load the required data while expanding the node. I made some examples mistake and modified it for my purpose. But in my case Ajax does not fire, what am I missing here?

XHTML part 

  & lt; H: form & gt; & Lt; P: panel id = "add_elev2list" header = "LFGEEEEE" collapsed = "true" toggle = "true" & gt; & Lt; P: tree value = "# {bookb.root}" var = "node" dynamic = "true" & gt; & Lt; P: ajax event = "select" update = "@ this" listener = "# {bookb.onNodeSelect}" /> & Lt; P: tree node & gt; & Lt; H: output text value = "# {node}" /> & Lt; / P: treeNode & gt; & Lt; / P: tree & gt; & Lt; / P: Panel & gt; & Lt; / H: form & gt;   
 Before loading the first level of the tree  
  Public Zero Trigger Tribune () {root = New DefaultTreeNode ("root", blank); ObjectContainer localdb = dbConnector.connDB (); ObjectSet & LT; SbasUserList & gt; Race; Query query = localdb.query (); Query.constrain (sbasUserList.class); //query.descend("klass").constrain(true); Res = query.execute (); (SbasUserList sbu: res) {if (sbu.isClass ()) {TreeNode node0 = New DefaultTreeNode (sbu.getGroupname (), root); Node0.get hair (). Add (New DefaultTreeNode ("head"); }} Localdb.close (); }   
 The Ajax event should trigger this which works fine, but it does not.  
  Node selects on public zeroes (nodeselected event) {log ("extension"); // wrapper for system.out.println ... SbasUserList sbu = (sbasUserList) nee.getTreeNode () for some types of debugging. GetData (); String [] allstd = sbu.getAllusers (). the division (","); ObjectContainer localdb = dbConnector.connDB (); For (string personal: alasted) {nee.getTreeNode (). GetChildren () Add (New DefaultTreeNode (Personal DB, Personal) (GetUserbyby). GetRealname ())); } Localdb.close (); }   
 Any ideas why?  
 Best regards Ralf

 You have not set the attribute  selectionMode = "single" .  
  & lt; P: tree value = "# {treeBasicView.root}" var = "node" dynamic = "true" selection mode = "single" & gt; & Lt; P: ajax event = "select" listener = "# {treeBasicView.onNodeSelect}" /> & Lt; P: treeNode & gt; & Lt; H: output text value = "# {node}" /> & Lt; / P: treeNode & gt; & Lt; / P: tree & gt;

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
