It happens not only with a connector, but every custom style. The error happens on save. I see the error already in OOo3.2.1., the version OOo2.4.3 had been OK.

I expect that the style:name attribute is changed or that at least the style:display-name attribute is changed.

I don't understad what do you exactly mean :) What are we going to do now ?

I detected the similar bug in Impress. :(((

Using the _toolbar button_ 'New Style' from the sidebar works as expected: the 'create style' dialog is shown and allows to enter the name, which is used and shown correctly afterwards.

Using 'New...' from the _context menu_ shows the full graphics styles dialog. Changes to the name field seems to have no effect. But actually it is saved, somehow, as you can see it in the list of existing styles in the 'create style' dialog.

It's not surprising that Impress is also affected since both share the same code base.

Thank you for your answer ! But, i said in the beginning that i can save the style ! 

"I can save a file and many properties of style such as color, font, arrow styles, transparency and so on".

Well, i have to say some words about my user experience relating to the support. I created more then 4 topics and bug reports on these sites: ask.libreoffice.org , forum.openoffice.org, bugs.documentfoundation.org. I am very appreciate for your answers, but it's a hard way to improve the product for ordinary end-users. We need a clear answer and plan to action with deadlines. This is a very important part of quality product.

Neither LibreOffice nor The Document Foundation provide _support_ as known from commercial products. We develop an open source product, which means everybody can and should contribute. Keep in mind that most of the people are volunteers, much of the code has a history dating back to star office, and many of the new features are implemented by students that may not continue their participation in the project.

This bug tracker organizes the work but is far away from being a work instruction. Your ticket _may_ be realized if someone cares about the feature. Unclear summary and lengthy reports are counterproductive. I tried to repeat your findings in comment 4. This ticket is a clear bug and has to get fixed. The other one in bug 101326 is not so obvious.
