Juno by default doesn&#39;t present the MRU (Most Recently Used) tab behaviour that you see in Indigo (it never worked quite right) and instead uses the Editor document order.

I believe you can re-activate it be either switching to the Classic theme in `Preferences&gt;General&gt;Appearance` or by editing the CSS.  See http://wiki.eclipse.org/Eclipse4/CSS

    .MPartStack {
        swt-mru-visible: true;
    }

Don&#39;t forget to restart Eclipse to make it use the new parameters.

Apparently this option was added in Eclipse Mars 4.5:

Window -&gt; Preferences -&gt; General -&gt; Appearance -&gt;

&gt; Visible tabs on overflow:
&gt; 
&gt; [X] Show most recently used tabs

Using EF5 with a generic Repository Pattern and ninject for dependency injenction and running into an issue when trying to update an entity to the database utilizing stored procs with my edmx.  

my update in DbContextRepository.cs is:

    public override void Update(T entity)
    {
        if (entity == null)
            throw new ArgumentException(&quot;Cannot add a null entity.&quot;);

        var entry = _context.Entry&lt;T&gt;(entity);

        if (entry.State == EntityState.Detached)
        {
            _context.Set&lt;T&gt;().Attach(entity);
            entry.State = EntityState.Modified;
        }
    }


From my AddressService.cs which goes back to my repository I have:

     public int Save(vw_address address)
    {
        if (address.address_pk == 0)
        {
            _repo.Insert(address);
        }
        else
        {
            _repo.Update(address);
        }

        _repo.SaveChanges();

        return address.address_pk;
    }

When it hits the Attach and EntityState.Modified it pukes with the error:

**An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key.**

I have looked through many of the suggestions in stack and on the Internet and not coming up with anything that resolves it.  Any work arounds would be appreciated.

Thanks!

What shell is used in Jenkins when calling the `shell` command? I&#39;m running Jenkins on a Linux machine.

I have been using Indigo for a while, and now trying Juno  
There is a sligth bothering difference:

On Indigo When you had 10 tabs opened

   A | **B** | C | D | J | H | G ....(F | T | S)

and currently on B  
when you selected the file shown in tab T again, then this tab (on **Indigo** and that&#39;s the problem not on Juno) would be repositioned like that:


   A | B | **T** | C | D | J | H  ....( G | F | S)

This is useful since, if opening T after B, it means they should be grouped together

on Juno it does not reposition them, instead you will need to find most recent files far in the tab list

Q: how to set it back? I searched params with &#39;tabs&#39; in the options with no result

edit: still the same in new versions (Kepler)

edit: Thanks to Paul&#39; answer, a good solution is to search for .css files in eclipse folder, and set swt-mru-visible property to true in e4-default-win7.css for example

I need to write a project that&#39;s only compatible with Java 1.5. I have Java 1.6 installed. Is there some form of backwards compatibility to get Eclipse to compile with 1.5?

Do I have to install Java 1.5 to get it to show here? Or maybe there is another way?

I have a ViewPager, and I&#39;d like to get the current selected and visible view, not a position. 

1. `getChildAt(getCurrentItem)` returns wrong `View`
2. This works not all the time. Sometimes returns null, sometimes just returns wrong View.

        @Override
        public void setUserVisibleHint(boolean isVisibleToUser) {
            super.setUserVisibleHint(isVisibleToUser);
    
            if (isVisibleToUser == true) { 
                mFocusedListView = ListView; 
            }
        }

3. PageListener on `ViewPager` with `getChildAt()` also not working, not giving me the correct View every time. 


How can i get current visible View?

    View view = MyActivity.mViewPager.getChildAt(MyActivity.mViewPager.getCurrentItem()).getRootView();
    ListView listview = (ListView) view.findViewById(R.id.ListViewItems);

I&#39;m confused as to what smart tabs do in general preferences.

It says that:

&gt; Fine alignment to a necessary column is done only via spaces... If
&gt; this check box is not selected, then spaces are used for alignment if
&gt; necessary...

Doesn&#39;t that mean that spaces are used in alignment for both cases?  Does it mean that it always uses spaces in the latter and only sometimes in the former?  

Can someone illustrate with an example of the two cases?

I&#39;m using bootstrap tabs and it works perfectly.
I&#39;m trying to figure out if there is a way to use bootstrap to give a border to the contents of the tabs that is connected to the border of the pill so it will look like one box. 
I tried doing this with my own css, but there is a cap between the tab pill border and tab content border that is a margin the tab pill needs to have and can&#39;t be removed.
I want it to look like the below image.

EDIT: It turns out this really isn&#39;t specific to Eclipse Kepler. I had to use the same process for Eclipse Juno. The problem was that there seem to be missing steps in other posts answering this same question.

I&#39;m using Eclipse Kepler for C++ and I&#39;m trying to use C++11 and getting errors. When I compile I get the error

error: range-based-for loops are not allowed in C++98 mode

I&#39;ve followed the instructions from the post

https://stackoverflow.com/questions/9131763/eclipse-cdt-c11-c0x-support

and the solution given for Eclipse Juno isn&#39;t working. 

Different comments have suggested restarting eclipse and cleaning and rebuilding. That hasn&#39;t made a difference.

How to enable C++11 in Eclipse Juno/Kepler/Luna CDT?

Ubuntu is usually a cutting edge distro. But why does it stick to a 2011 version of Eclipse when we are 4 years into `4.x` development?

It&#39;s not even optional and cannot be installed from the repositories. And it&#39;s not &#39;easy&#39; from a download either. For some reason, the Java SE 7 reference implementation, OpenJDK, is not enough, and you need the Oracle version. Why? This isn&#39;t available from the repo&#39;s either, and you need some weird untrusted 3rd party repo for that or follow a whole chapter on [how to install it yourself](http://terminaltwister.com/installing-oracle-java-7-sdk-on-ubuntu-13-04/).

There were problems three years ago. When `Juno 4.2` came out, it had a lot of [performance issues](http://www.jroller.com/andyl/entry/something_is_really_broken_with). Eclipse Director Mike Milinkovich [explains](http://mmilinkov.wordpress.com/2012/09/10/juno-performance/) one of the reasons is lack of funding. For the first time in a major release:

&gt; _&quot;The performance test were turned off because the Eclipse platform team has a serious resource issue.&quot;_

For that reason, developers released [unnamed and unpromoted](http://en.wikipedia.org/wiki/Eclipse_ide#cite_note-15) version `3.8` simultaneously with `4.2` to bridge the gap for this (hopefully) temporary problem, and it&#39;s popularity caused a notable [trend downwards](http://ianskerrett.wordpress.com/2013/06/12/eclipse-community-survey-results-for-2013/) amongst developers. As one `Eclipse b3` developer [mentioned](http://www.infoq.com/news/2012/09/eclipse-juno-performance):

&gt; _&quot;I was stunned by the performance improvement after the switch. The 3.8 platform is much MUCH faster&quot;_

The `3.8` release is still a popular alternative to the `4.x` branch among developers (ask my colleagues or google), I think mainly because of (genuine) trust issues. But the bridge (read: support for `3.8`) has closed now that `4.3` is released. 

The core problems (funding and developers) have not been fixed though, as seen by Google&#39;s [gesture of donating money](http://www.zdnet.com/google-sets-perfect-example-with-20000-donation-to-eclipse-7000003968/) to the Eclipse Foundation in the hopes that other companies will follow suit. Does this mean that `4.3` is still not up to par with the `3.x` standards?

This is not a problem with a plugin or a feature for a specific language, this is a [problem](https://bugs.eclipse.org/bugs/show_bug.cgi?id=362718) within the core of the platform itself. (But I&#39;m using WST with Javascript and V8 plugins for PHP and Node development in particular.)

This is not a specific platform problem either. There are [similar complaints](https://bugs.eclipse.org/bugs/show_bug.cgi?id=385272) from Linux, Windows, and OSX users. (But I&#39;m using Linux (Mint 13).)

---
On the one hand you have people telling the EOL for `3.8` *&quot;proves&quot;* that `4.3` is fine now. On the other hand (see comments):
&gt; _&quot;I&#39;ve moved back to 3.8 due to constant crashes on ubuntu with 4.3&quot;_

`3.8` is far from problem-free and I wouldn&#39;t mind to get a smoother development experience. So I am wondering, why is Eclipse 4 *&#39;kept from us&#39;* by the people who decide what software versions are *&#39;good for us&#39;* (AKA what goes into the official repository)?



* lucid (10.04 LTS)
  * Eclipse 3.5.2-2
* precise (12.04 LTS)
  * Eclipse 3.7.2-1
* raring (13.04)
  * __Eclipse 3.8__.1-1
* saucy (13.10)
  * __Eclipse 3.8__.1-4
* trusty (14.04 LTS)
  * __Eclipse 3.8__.1-5.1
* utopic (14.10)
  * __Eclipse 3.8__.1-5.1

__Update 2014-05-30:__ I just tried Kepler (again) and it still suffers from UI glitches out of the box. E.g.:

![enter image description here][1]

And no, changing the inactive window toolbar background color in preferences does _not_ fix this. (Even if it would, this would be a silly default choice).

I would like to know, from someone who is not positively or negatively biased because of their own highly specialized and tweaked workflow - preferably from someone with experience in the Ubuntu package maintaining process for non-trivial packages - _why_ this decision is made by a team of professionals who know what they are doing for the most widely used Linux distribution out there?
