Description jwswart 2010-09-13 07:12:58 UTC 
Product Version = NetBeans IDE 6.9.1 (Build 201007282301)
Operating System = Linux version 2.6.32-24-generic running on i386
Java; VM; Vendor = 1.6.0_17
Runtime = Java HotSpot(TM) Client VM 14.3-b01

This is the problem I have:

1) Modify file
2) Save file
3) Alt-tab to another application (ie. Netbeans loses focus)
4) Switch back to Netbeans
5) CTRL+Z and CTRL+Y no longer work.

Initially I thought this was because of the reasons described in this forum post:

http://forums.netbeans.org/post-84316.html

But that does not seem to be the case.  My NTP is set to synchronize with the server that I am saving my project on.

I use Netbeans 6.9.1 for PHP and I save my files to a SAMBA share on another Linux server on our LAN.

I should point out that sync'ing NTP did solve the initial problem of constantly being told my file has been modified externally.  But it does not solve the CTRL+Z undo problem.

Note: it seems to be specifically when Netbeans loses focus.  I am able to save the file and undo my changes as long as I remain in the IDE.

Any help would be greatly appreciated.

Works for me NB 7.0 M2, Ubuntu 10.04  x64, JDK 6u22

I'm using still 6.9.1 because of python plug-in and having the same problem. It did not work from the beginning.

My System:

Ubuntu 11.04 (32bit)
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) Client VM (build 20.1-b02, mixed mode, sharing)

Hi, since reporting this bug, I managed to get it working by changing from a samba mount to SSHFS.

The mount that I have in fstab that resolves the undo problem looks like this:

sshfs#username@hostname: /mnt/mountpoint fuse defaults,uid=<uid>,gid=<gid>,umask=0,allow_other,workaround=rename 0 0

uid and guid are those that appear in /etc/passwd for your username and without <> of course.

In this instance I have set up a public key/private key relationship with the server so I do not have my credentials in the fstab setting, but adding them should be fine.

Basically the problem is resolved by using sshfs rather than samba, and specifically using the 'workaround=rename' flag that sorts out netbeans saying that files already exist or have changed, etc.

It looks like it has something to do with lockability tests in platform/text thus reassigning.

Hello, I don't think we want to fix this. Although I admit that it might be a problem for some users, a workaround for IDE users is rather simple: don't use remote mounts for working with the IDE. Closing as wontfix.
