Multi-Select Checkbox Property

howejr77 — Thu, 10 Jul 2008 17:22:06 GMT

Hello,I'm trying to create a custom aspect containing a property which I will tie to a multi-select set of checkboxes. I'm looking for a dynamic way to generate the contents for the checkboxes. In my searches so far, the most concrete way I've seen to do something like this appears to be to define a

Well, I have successfully retrieved the contents of the constraint list by creating a custom constraint that extends ListOfValuesConstraint. Now when I visit the properties page of a piece of content with that aspect attached to it, I successfully get a component displayed on the page that has my list of values from a database table.

I'm now having an issue where I'm trying to access the getSelectItemList() method on my custom constraint from a custom JSP page in a custom wizard but I don't appear to have a reference to the instance that is being created during the Alfresco startup. Could someone give me some advice on how to access it? I've seen the posts on making a class ApplicationContextAware but when I implement those examples, my setApplicationContext method never seems to be called as I get a null pointer when I try to access the ApplicationContext. Is there some configuration I need to do with a class that I make applicationContextAware?

Is there a way to reference my custom constraint class via the FacesContext?

Please help! I keep trying to post to these forums but it seems like no one ever replies…

Thank You
Ryan

OK, solved my problem with the nullPointer in getting access to the ApplicationContext.

Could anyone give me any clue on the name of the bean I want to retreive?

Assuming this is my custom model constraint definition:

    <constraints>
        <constraint name="pfxfxPossibleRoles" type="com.sample.constraint.AllowedRoleConstraint" />
   </constraints>

Could someone please help or at least give me a clue that I'm going down the correct path?

I've create my "Add Content" dialog and am trying to display a Select Many Checkbox using the getSelectItems from my custom constraint. I've gone through all the activity of above and have access to ApplicationContext now but really don't see how to access the instance of my custom constraint that was created at Alfresco startup.

I see the DictionaryBootStrap bean for my custom model but don't see anyway to get my constraint…

Please help… Someone…

I've posted several different posts through this forum and only one thread received any responses….

Hi
I have the same problem you are talking about.
Can you provide some example file for model.xml and web-client.xml ?
Thanks in advance.

Hi,

I struggled through this a little while ago so all the various problems I hit, are a little fuzzy to me right now. Definitely want to help though as I know I had to just search and search for the most part. I'm assuming you are trying to access the values in a ListOfValuesConstraint which you created? That is what I'll try to describe here. If I'm not covering what you need, let me know what you are after…

The main thing you need is a reference to the DictionaryService object. In my tasks, I was creating dialogues/wizards that ulimately extended BaseDialogBean which has a reference for you.

Once I had DictionaryService, from searching all over I ended up writing these two methods:


        private PropertyDefinition getProperyDefinition(String aspectLocalName, String propertyLocalName) {

      AspectDefinition pbContentPropsAspect = ds.getAspect(QName.createQName(CustomModelHelper.PB_NAMESPACE_URI, aspectLocalName));
      Iterator<PropertyDefinition> propDefIter = pbContentPropsAspect.getProperties().values().iterator();
      while (propDefIter.hasNext()) {
         PropertyDefinition propDef = propDefIter.next();
         if (propDef.getName().getLocalName().equalsIgnoreCase(propertyLocalName)) {
            return propDef;
         }
      }
      
      return null;       
        }
  
   public PBListOfValuesConstraint getPBValueConstraint(String aspectLocalName, String propertyLocalName) {

      PBListOfValuesConstraint pbLOVConstraint = null;
      
      PropertyDefinition pbRoleAccessPropertyDef = getProperyDefinition(aspectLocalName, propertyLocalName);
      ListIterator<ConstraintDefinition> constraintDefIter = pbRoleAccessPropertyDef.getConstraints().listIterator();
      while (constraintDefIter.hasNext()) {
         Constraint constraint = ((ConstraintDefinition)constraintDefIter.next()).getConstraint();
         if (constraint instanceof PBListOfValuesConstraint) {
            pbLOVConstraint = (PBListOfValuesConstraint) constraint;
         }
      }
      
      return pbLOVConstraint;
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I believe I found the logic of these two methods in the forums somewhere but just restructured them a bit. Let me know if this helps you or you need more information (or if you were asking for something other than finding your constraint via the DictionaryService). With Labor Day weekend, I may not be able to respond before next week..
