URGENT HELP !!! showing the association as a hyperlink

hey123 — Mon, 11 Dec 2006 14:21:01 GMT

Hello,I am defining a new content type with a child content association. But, when I want to view the properties of an object of this content type, child associations are shown like below:Incoming Documents: /company_home/README.txt /company_home/11111111RE

Hi,

I've been also trying to link documents but couldn't find out how to view them as links instead of xpath. I don't know if this could be done only by configuring xml files, maybe that would suppose modifying interface.
I'll be watching this topic.

Basically the generic child association editor is being used. This can be overridden by using the component-generator attribute in the config file, however, you need to create a custom component generator.

Have a look at the following wiki pages as a start:

http://wiki.alfresco.com/wiki/Displaying_Custom_Metadata
http://wiki.alfresco.com/wiki/Component_Generator_Framework

Once you have an idea of how to go about it, you'll need to create a component that shows whatever is at the end of the child association i.e. an image when the component is in read-only mode.

Hi Gavinc,
I looked at the wiki pages.
At the end, I decided to use NodePath component of alfresco and I created a generator for it. Steps that I took were:

1-I created a jar file including the following source code

package org.alfresco.web.bean.generator;

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;

import org.alfresco.web.app.servlet.FacesHelper;
import org.alfresco.web.ui.repo.RepoConstants;
import org.alfresco.web.ui.repo.component.property.PropertySheetItem;
import org.alfresco.web.ui.repo.component.property.UIPropertySheet;

/**
* Generates a component to manage child associations.
*
* @author gavinc
*/
public class CustomNodePathGenerator extends BaseComponentGenerator
{
   private String disabled;

   public UIComponent generate(FacesContext context, String id)
   {
      UIComponent component = context.getApplication().
            createComponent("org.alfresco.faces.NodePath");
      FacesHelper.setupComponentId(context, component, id);
      component.getAttributes().put("disabled", this.disabled);
      return component;
   }

   @Override
   protected void setupMandatoryValidation(FacesContext context, UIPropertySheet propertySheet,
         PropertySheetItem item, UIComponent component, boolean realTimeChecking, String idSuffix)
   {
      // Override the setup of the mandatory validation
      // so we can send the _current_value id suffix.
      // We also enable real time so the page load
      // check disables the ok button if necessary, as the user
      // adds or removes items from the multi value list the
      // page will be refreshed and therefore re-check the status.

      super.setupMandatoryValidation(context, propertySheet, item,
            component, true, "_current_value");
   }

public String getDisabled() {
   return disabled;
}

public void setDisabled(String disabled) {
   this.disabled = disabled;
}
}

2-Then I add the following lines to faces-config-custom.xml

<managed-bean>
   <managed-bean-name>CustomNodePathGenerator </managed-bean-name>
   <managed-bean-class>org.alfresco.web.bean.generator.CustomNodePathGenerator</managed-bean-class>
   <managed-bean-scope>request</managed-bean-scope>
   <managed-property>
      <property-name>disabled </property-name>
      <value>true</value>
   </managed-property>
</managed-bean>

3-Then I add the following lines to web-client-config-custom.xml
<show-child-association name="my:incomingDocuments" component-generator="CustomNodePathGenerator" display-label="Incoming Documents"/>

But nothing happened.

Even I tried each of the followings:

<show-child-association name="my:incomingDocuments" converter="org.alfresco.faces.DisplayPathConverter" component-generator="CustomNodePathGenerator" display-label="Incoming Documents"/>

<show-child-association name="my:incomingDocuments" converter="org.alfresco.faces.DisplayPathConverter" display-label="Incoming Documents"/>
And again I got nothing. Can you help me please.

Thank you in advance.

Re: URGENT HELP !!! showing the association as a hyperlink

gavinc — Wed, 13 Dec 2006 16:44:22 GMT

When you say nothing happens what do you mean?

Do you see the association at all i.e. the default component? Are there any errors reported? Remove the comment for the line "#log4j.logger.org.alfresco.web.ui.common.Utils=info" in log4j.properties and try displaying the property sheet again.

However, this component was not designed to work within the property sheet and has therefore not been tested in this configuration so I'm not sure whether it's going to work, it may well be relying on some context that is not available within the property sheet.

Re: URGENT HELP !!! showing the association as a hyperlink

hey123 — Wed, 13 Dec 2006 19:46:37 GMT

Nothing changed in the child association part,
while waiting for your answer, to understand whether there is a problem in showing this new generator in the property sheet, I tried using this generator for a text area field, and then the property sheet could not show it, so you are probably right that it is giving error messages in the background.

Sir,
as a result, just to show the text in hyperlinks do I have to write a new component ?

And if this is the only solution, can you advice me a preexisting component to just copy, paste and make as little as possible changes to reach the result.

Thank you very much for your previous quick response. I am trying to finish this for a very important demo to our clients.

Hopefully that client will want to pay for support 🙂

Urgent help from the core engineers via the forums is asking them to be very nice to you! They only get their salaries from the paid support that people take out.

Cheers

We were trying to sell(not actually sell you know getting support training etc.) alfresco to them ,
anyway I will say in the demo that, this is just a trial version and at the end they will be able to see the documents.

Thanks.

gavinc — Thu, 14 Dec 2006 19:19:41 GMT

Unfortunately, yes, it looks like you'd need to write a new component to achieve the result you need.

The component you tried to use probably has the code in it you'd need to generate the link. Just follow the pattern for any other self rendering component, for example, UINodeWorkflowInfo.

couldn't we use the actionLink defined here ?

http://wiki.alfresco.com/wiki/ActionLink

Hi,
in fact I don't know whether this works, I will look into action links.
I solved my problem not by writing a new component, but by changing the alfresco source code of related component, namely UIChildAssociationEditor. If you need it you can also change it, or if you want I may send it to you.

Have a nice day.

aznk — Thu, 21 Dec 2006 08:48:46 GMT

Hi,
Sounds weird that we have to all this fuss just to show the path as a link.
Yes it would be very nice if you could sent it to me, or tell me which files you changed/added.
Thanks a lot and have a nice day.

Hello,
this is the file that I changed,
but please note that since this was just a demo, I solved the problem in a quick and dirty way, i.e. by just adding the "http://...vs" line. (hardcoded)
So it needs more work.

Thanx for your code. Btw did you use SVN for developing ? Because I'm currently working with SDK, I wondered if it was possible to develop easily component generators, because deploying with SVN takes a lot of time…

Re: URGENT HELP !!! showing the association as a hyperlink

Can someone please tell me where I could find UIChildAssociationEditor.java so I can replace it with the one here on the forum. I did a search for it but couldn't find it. I use Alfresco 2.0 Enterprise Edition, if that is any help.

Hope you can help me out, thanks!!

Re: URGENT HELP !!! showing the association as a hyperlink

While trying to do the same thing (making child-associations clickable in the property sheet), I noticed that the UIChildAssociation class ignores overridden "component-generator" attributes (RepoConstants.GENERATOR_CHILD_ASSOCIATION is used instead).
The UIProperty class on the other hand does allow overriding of this attribute (this.getComponentGenerator()).

Is there any chance that the "component-generator" attribute will be overridable for show-association and show-child-association tags as well in a future release?

Since my project must be packaged as a module, I cannot alter the UIChildAssociationEditor class, nor can I override the managed bean ChildAssociationGenerator or the component org.alfresco.faces.ChildAssociationEditor.
