Exceptions adding custom aspect

rmangi — Wed, 28 Dec 2005 17:09:17 GMT

Hello all. I'm trying to create a custom aspect and apply it to content and I'm getting exceptions. It's a very simple aspect, just really trying to create a stub so I can play. Following are the steps I've taken: XML for the aspect: repository/config/alfresco/extension/projectModel.xml<?xml vers

Hi,

Apologies for missing your previous post.

The problem is that you are referencing the model name and not the aspect name. In your model you have the following snippet:

<aspect name="gto:project">
   <title>GTO Project Specification</title>‍‍

The aspect name is gtoroject so in the web client config files you should be using this and not "gtorojectModel".

So for example in web-client-config.xml and web-client-config-edit-properties.xml you should use the following evaluator expression:

<config evaluator="aspect-name" condition="gto:project">‍

The same also goes for the reference in the Action Wizards section.

Hope that helps.

I did what you wrote, but after try to apply an aspect in a rule, when it will show the aspect list available, in fact show the errors in UI:
javax.faces.FacesException: Error calling action method of component with id new-rule-condition:set-add-button

caused by:
javax.faces.el.EvaluationException: Exception while invoking expression #{NewRuleWizard.promptForConditionValues}

Hi Gavin,

That worked! Thanks. Ok, but now I have another question on this same topic. So I added the aspect to a space using a rule based on the name "Project*". I created a new space and it adds the aspect. When I go to edit the properties of this space it shows the fields I've added, but they are greyed out and I can't change them, just blank values. How do I edit these values?

What I'm trying to do is to add some custom properties to certain spaces which represent Projects in our firm. This data should be attached to the Project (space) not to the documents in the space, things such as client name, project code, create date, that sort of meta data.

Thanks,

Rick

Besides this case above, I have a doubt eigther. After create the aspect, I changed the name of a propertie,
It was "nomeCLiente"
I changed to "nomeCliente".
But Before I change it, I'd already assigned the aspect to one document, and after I change it (redeployed it). So, the propertie "nomeCliente" doesn't appears now. How could it be, neigther that already assigned ("nomeCLiente")?
(I wait by the answer of rmangi question too)
Tks

I presume you are talking about the 'View Details' page for the space where the the properties are shown but grayed out.

The list of properties that appear here are driven from the configuration file (web-client-config.xml). The list is built from all the property-sheet config found for each applicable type and/or aspect. rmangi has an example of this at the beginning of this topic. hsp, have you updated your config to show "nomeCliente" instead of "nomeCLiente"?

To edit the properties you can click on the small icon in the title bar of the Properties panel (on the right hand side). This should take you to the edit properties page for the space. If you don't see this icon it means you do not have the permissions to edit.

However, unfortunately, the edit space details page is not dynamic at the moment (unlike the edit content properties page) meaning that despite what you have configured in web-client-config-edit-properties.xml none of the properties will show up.

We will be fixing this in the release after 1.2, so in the meantime you will have to create your own details page. You could use the same technique the forums use to dispatch to your own page instead of the standard one. To do this you would need the following config:

<config evaluator="aspect-name" condition="gto:project">
   <property-sheet>
      <show-property name="gto:projectName"/>
      <show-property name="gto:clientName"/>
      <show-property name="gto:entryDate"/>
   </property-sheet>

   <navigation>
      <override from-outcome="showSpaceDetails" to-view-id="/jsp/your/aspect-details-page.jsp" />
   </navigation>
</config> ‍‍‍‍‍‍‍‍‍‍‍

You will then also need to create a backing bean for your new page to take the properties entered by the user and update the node in the repository.

If you want to use this approach you will need to get the latest source from SVN or the nightly build.

Hope this helps.

hsp, have you updated your config to show "nomeCliente" instead of "nomeCLiente"?

I have not been placed in the file customModel.xml. Ok Thanks.

Gavin,

That's exactly what I needed to know. Thank you.
