document.properties = null

[pigtaro]

Hi All,

This is my first post. I am trying to add category to a new document. From the web, i got the following code:

var catNodeRef = search.luceneSearch("…");
var cats = document.properties["cm:classifiable"];
cats.push(catNodeRef);
‍‍‍‍‍

I keep getting null error. After turning on the Alfresco Javascript debugger, i discovered that document.properties is null. Been searching for the web ever since, but unable to get answer. How do i instantiate the properties attributes in the document?

regards,
Steven

I think you have to post the code that creates 'document', because with the code you've posted there's no way to know the type of that variable.

Apologise… still newbie is alfresco…

I want to execute my script in the rule, so that i can tag any incoming documents with a category.

My script is actually this: 

document.addAspect("cm:versionable");
document.addAspect("cm:generalclassifiable");

for each (cl in classification.getAllCategoryNodes("cm:generalclassifiable")){
  if(cl.name == "Test Plan"){
     document.properties["cm:categories"].push(cl);
  }
}
‍‍‍‍‍‍‍‍‍‍

document should point to the incoming file because the addAspect works. However, the document.properties is null, so the following line give a null error.

document.properties["cm:categories"].push(cl);
‍‍‍

Hope my explanation of my problem is clear.

After experimenting, i found that it is not document.properties = null.

This is what i derive, so please correct me if i am wrong. When i add aspects to a document, document.properties has added properties based on the contentModel.xml. So when i add versionable, cm:versionLabel, cm:initialVersion, cm:autoVersion is added into the docment.properties.

However, when i addAspects("cm:generalclassifiable"), no new properties are added into the document.properties. The contentModel for the generalclassifiable is as follows, i did not make any changes to it, so it is what was downloaded in the alfresco package.

      <aspect name="cm:generalclassifiable">
         <title>General Classifiable</title>
         <parent>cm:classifiable</parent>
         <properties>
            <property name="cm:categories">
               <title>Categories</title>
               <type>d:category</type>
               <mandatory>false</mandatory>
               <multiple>true</multiple>
               <index enabled="true">
                  <atomic>true</atomic>
                  <stored>true</stored>
                  <tokenised>true</tokenised>
               </index>
            </property>         
         </properties>
      </aspect>

So the solution would be to, if your attribute cm:categories doesn't yet exist, to create an array and initialize your attribute with it.

Ha… got it working after creating an empty array and initialize the "cm:categories" to the document.properties. Thanks rogier.oudshoorn.
