Show or hide temporarily a tab

A1234 — Thu, 03 Mar 2016 11:05:08 -0500

We wish to temporarily hide a tab of a RTabbedPane.

We know how to hide its content with the visible attribute, but we want it to disappear completely from the tab bar, without removing it.

This is like trying to prepare in advance a tab and to show or hide it depending on whether a certain condition is met or not.

Has anyone a suggestion about how to do it?

getProcessElement() not found when migrating to Ivy 6

A1234 — Mon, 14 Dec 2015 15:03:18 -0500

Hello,

While testing migration of various projects to Ivy 6.0, I encountered a problem with a method that does not exist anymore.

  /** 
   * Find the current process name. 
   * 
   * @return fully qualified process name 
   * @throws Exception 
   */ 
    public static String getName() throws Exception {
        return SecurityManagerFactory.getSecurityManager().executeAsSystem(new Callable<String>() {
            public String call() {
                IProcess process = ProcessNavigationUtil.getProcess(MetaData.getProcessElement());

                if (process != null) 
                    return process.getPath();

                return null;
            }
        });
    }

In the previous code, the method MetaData.getProcessElement() is not found. By looking in Ivy 5.1.7, it was implemented as:

  public static ZObject getProcessElement()
  {
    return (ZObject)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

Now the method has been removed, and a new method getProcessElementId() was added, but with a new signature:

  public static PID getProcessElementId()
  {
    return (PID)IvyThreadContext.getIvyThreadLocalValue("processElement");
  }

I didn't found this change in the migration documentation. Can I know the reason for removing the previous method and what are the alternative in order to get the current process name? Thanks.

How can I update Subclipse in Ivy with 1.8.x client?

A1234 — Tue, 11 Aug 2015 17:43:12 -0400

Hello,

I read How can I update Subclipse in Ivy? - Axon.ivy | Q&A and tried to apply a similar receipt to update Subclipse to get the 1.8 client.

Unfortunately, the Update function does not found anything.

If I install http://subclipse.tigris.org/update_1.10.x and select both Subclipse (Required) and Subversion Client Adapter (Required), the install succeeds.

But when I select Subversion JavaHL Native Library Adapter, the install fails with the following message:

An error occurred while collecting items to be installed
session context was:(profile=DefaultProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

I tried to install from the URL and from a local ZIP (http://subclipse.tigris.org/files/documents/906/49431/site-1.10.9.zip), but it always fails with the same error.

Could you please provide a way to update the Subversion client in Ivy Designer 1.5.7 in order to leverage the 1.8 client feature (and working copy format)? Thanks.

I would like to modify a log level in production without having to restart the server

A1234 — Fri, 28 Nov 2014 16:49:39 -0500

Sometimes we want to change the level of logging of a server in production.

I am not sure this is possible without restarting the server, which is often difficult to manage depending of the customer.

I know that log4j supports a way to dynamically reload the configuration when a file change has been detected. See configureAndWatch.

Is it supported in Ivy 4.x/5.x? Is there something we can do to enable this feature?

Debugging a RD process running on a remote server

A1234 — Fri, 14 Nov 2014 09:58:28 -0500

Hello,

I followed the directives to debug a remote server, as described in How can I debug my Java class in the Designer?.

That works well, I can set breakpoints on Java class statements, and debug the code.

I would like to know if it possible to also debug a RD process by setting breakpoints on process elements?

I don't see how to have my breakpoints stop when they are executed. I started the engine, but that does not work.

Is Java 8 client-side supported with Ivy 5.0 and 5.1 RIA applications?

A1234 — Tue, 11 Nov 2014 14:03:43 -0500

Several customer ask to remove Java 7 and install Java 8 on their desktops.

Is it officially supported with Ivy 5.0/5.1 applications ? Do issues have already been identified?

How to get web resouces images defined in a CSS file?

A1234 — Mon, 18 Nov 2013 17:18:36 -0500

Hello,

In an HTML dialog, if I use either of the following instructions for importing a style:

<h:outputStylesheet name="portlet/css/presential.css"/>

<link rel="stylesheet" href="#{resource['portlet/css/presential.css']}" type="text/css"/>

the CSS file is loaded (see line #1 below) with the request attribute "?ln=xpertivy-14-WebContent".

Unfortunately, it cannot find the images defined in the CSS (see 2 last lines). Notice that the request attribute above is not appended to the image request.

This could be important because if I manually request the following URL: http://localhost:8082/ivy/faces/javax.faces.resource/portlet/images/clock24.png?ln=xpertivy-14-webContent

I can successfully get the clock24.png image.

Is it actually a bug, or is there a particular way to do it?

Thanks.

How to set icons in PrimeFaces tree nodes

A1234 — Fri, 15 Nov 2013 12:05:59 -0500

Hello,

I would like to set icons in PrimeFaces tree nodes. My icons are configured in the project CMS.

Unfortunately, the Resource Demo doesn't help me.

<p:tree id="treeSingle" value="#{treeBean.root}" var="node" selectionMode="single"
        selection="#{treeBean.selectedNode}">
  <p:treeNode icon="">
    <h:outputText value="#{node.name}" />
  </p:treeNode>
</p:tree>

In <p:treenode> I need to set the icon attribute with a syntax that will retrieve icons from the CMS.
