Alfresco Share and onCreate policy (customized behaviour)

itrub — Thu, 23 Jun 2011 14:43:16 GMT

Dear colleaguesI have a question about very interesting problem, that, seems, was not discussed before. So, I try to explain it as clear as possible. I wrote the new behaviour class, that realizes policy "onCreate" relationaly to documents of type SomeType. It works successfully, when I create Some

Easy fix, change Share so that you can set the type on upload.

Good afternoon, Loftux and all Alfresco developers
I have tried decision, proposed by Loftux. Yes, now I can choose the type of document during uploading file. But behaviour "onCreate" does not fire all the same! It fires well, when I create document in Explorer. What is the reason? Did anybody check custom behaviour "onCreate" under Share interface at all? It seems to me, behaviour-feature is available only under Alfresco Explorer interface. Do you agree with me?

I Agree, and withdraw my statement. This was not an easy fix :roll:

If you look at the rest api used in the upload
http://localhost:8080/alfresco/wcs/script/org/alfresco/repository/upload/upload.post
you see that

/**
          * Create a new file.
          */
         var newFile = destNode.createFile(filename);
         if (contentType !== null)
         {
            newFile.specializeType(contentType);
         }‍‍‍‍‍‍‍‍

it is first created, then specalized to the type. So your policy will not fire.
I looked for an alternative policy that could be useful in this case http://dev.alfresco.com/resource/docs/java/repository/org/alfresco/repo/policy/Policy.html like onSpecializeType, but there don't seem to be one. I think it would be useful if you file an enhancement request for this.

What you can do is change the upload script to set the type on create. You can do var newFile = destNode.createNode(filename, contentType)
and with some testing of course that the contentType is not null. http://wiki.alfresco.com/wiki/3.4_JavaScript_API#Modifying_and_Creating_API
Not sure if there is any other difference that you have to account for using the 2 different ways of creating new nodes.

Hello, Loftux and other colleagues
Many thanks, Loftux' decision is completely workable, policy has become to fire now from Share. The only detail remains unclear. Loftux, on your blog you write:
"You also need to extend the file flash-upload.get.properties, in this case also html-upload.get.properties.
Add the value for “value” in the javascript for each of you custom types.
1 my_customtype=My Custom Type "

I have followed your instruction, but typenames in "select"-element appear under their system names, records similar "My Custom Type" are ignored. May be, it is necessary to extend some other files? But this is not important detail. I think, problem may be marked as solvable.

Create a file named itrub-context.xml (name it as you like, as long as it ends in -extension.xml) in folder web-extension

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
   
   <bean id="itrubResourceBundle" class="org.springframework.extensions.surf.util.ResourceBundleBootstrapComponent">
      <property name="resourceBundles">
         <list>
            <value>alfresco.messages.itrub</value>
         </list>
      </property>
   </bean>
   
</beans>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

In shared/classes/alfresco/messages, create a file itrub.properties for english message bundle, itrub_it.properties for italian and so on.
The <value> tag as you can tell specifies the classpath, and finally the expected file name (without properties ending in the value tag)

My blog post was written prior to med finding out where to add you custom message bundles, this is a better way to do it
