Re: [atf-dev] NullPointerException when using ATF

Try working from the Java Perspective.
The Package explorer or the Navigator should allow you to view the existing
Web Project. In this release a project created with a previous version
of ATF doesn't have the full functionality of a project created with the
new version of ATF, but the basic ATF functionality like debugger and browser
tools should still work. The new functionally provided by JSDT would not
be available in a project created by a previous version of ATF. To get
the full functionality you need to create a new Ajax project and copy your
old files into the project. 

Can you give us more information about
the existing Web Project? Which version of ATF was used to create the previous
Web Project? 

   Thanks
     Bob

Marcus-- There have been many changes to ATF in
this release that may cause issues with projects created before the new
release is installed. A workaround on your end is to copy the files out
of your project into a temp directory at the OS level, delete the original
project and create a new one. Then re-import the files into the new project.


Javier-- 

I'm not sure precisely what is causing Marcus' error. My guess is that
getToolkitFolders() is causing the NPE or else its not returning any folders
(causing an NPE further down). Has the way ATF keeps track of runtime folders
changed? The (quick) fix below should work for now.


(org.eclipse.atf.compatibility.jsdt.ATFClasspathContainer.getClasspathEntries():140)
:

============================================
public IClasspathEntry[] getClasspathEntries()
{
IFolder[] toolkitFolders = getToolkitFolders();

....

=============================================
goes to :
=============================================
public IClasspathEntry[] getClasspathEntries()
{
IFolder[] toolkitFolders;

try {
toolkitFolders = getToolkitFolders();
} catch
(Exception ex) {
toolkitFolders = new
IFolder[0];
}


...
==============================================

Subject	[atf-dev] NullPointerException when using ATF

With ATF 0.2.3M3 I get an error pop-up saying a NullPointerException 
occurred when initializing the _javascript_ tooling. This happens when I
open the Web Development perspective, and also when I try to open an 
existing web project. (As a result, the Project Explorer doesn't show 
the files in my web project - I cannot expand the project directory 
although it isn't empty.)

The log is attached.

Regards,

Marcus
