Delete File Error

[fracat71]

Hi all,
I'm using

- ALFRESCO: Community Current version 3.2.0 (r2 2440) schema 3300
- OS: Windows xp 32 bit , RAM 2,5G , Intel Core Duo 2,1 GHz
- AS: Tomcat 6.0.18
- JAVA: Jdk 6.0_11. Heap 986,125MB
- DB :Mysql 5.1.35 Communit


When i try to delete a file from list it is ok.
When i try to delete a file from "view details" i have this error:

javax.faces.FacesException: java.lang.NullPointerException
caused by:
org.apache.jasper.JasperException: java.lang.NullPointerException
caused by:
java.lang.NullPointerException

Probably it is a wrong return page.
What i have to change?

Regards

[savic_prvoslav]

well the problem is  null pointer hire:

return this.browseBean.getDocument();

because eather browseBean is null or documetn is null ( 100$% is brose bean)
document is current file.

if this is a bug you can fix it easy with  next code and overrriding DocumentDetailsDialog .

/**
    * Returns the Node this bean is currently representing
    *
    * @return The Node
    */
   public Node getNode()
   {

if(browseBean==null)
{
browseBean =(BrowseBean) FacesHelper.getManagedBean(FacesContext.getCurrentInstance(), "BrowseBean");
} 
      return this.browseBean.getDocument();
   }‍‍‍‍‍‍‍‍‍‍‍‍‍‍

also check the faces-config-beans.xml for BaseDetailsBean and see if browse bean has been defined.

Hi,
i cannot attach my faces-config-beans.xml (too longer),
i dont' change it (it is the Alfresco 3.2r2 default) but i don't have the definition of BaseDetailsBean.

Regards.

hallo savic….
sorry… i little bit confuse… what file i should override?
i don't find any file with name DocumentDetailsDialog…

[savic_prvoslav]

You need some java coding , you do not override file -you overreide java class .

I think that browseBean is null or documetn is null because Alfresco redirects on a deleted object: is it possible?
The same delete on a folder works fine.

Hi savic,

I've override DocumentDetailsDialog as suggested but the same error still happen, I also check the file faces-config-beans.xml in DocumentDetailsDialog already define BrowseBean.

Are there any other suggestions to fix this problem?

Thank you.



DocumentDetailsDialog.java

   public Node getNode()
   {
      if(browseBean==null)
      {
         browseBean =(BrowseBean) FacesHelper.getManagedBean(FacesContext.getCurrentInstance(), "BrowseBean");
      }       
      return this.browseBean.getDocument();
