Re: [jbpm-dev] Fwd: Re: [jbpm-users] local history for the jbpm web editor

Hi Gabor, finally found some time to work on this. Should be done in the next day or so and will post a video here first for review and comments before making it public (committing). I'd like for you to send me some text about yourself that I can put on the blog when writing about this new feature - just anything you would want readers to know about you. If you could send me that this week I'd really appreciate it. Thanks. On 10/25/12 4:55 PM, Gábor Farkas wrote: Hi, So, I cleaned it up a bit and put some comments. I guess it's not nice to attach files on a public mailing list, so I uploaded a package here: https://docs.google.com/open?id=0B3W14YRqXKCZc0RVSjlPWklka2s If you unzip the folder somewhere, the editor.html can be loaded statically from the file. I have this folder so that I can test some changes faster, without actually starting the editor. To install it in the actual editor, you have to put the localhistory.js on the web root (next to editor.html), and add this fragment to the editor.html (right after div class='processdata' for example, in the body element) <div id='lsDiv' title='LocalHistory for teh LuLz' style='position:fixed;top:0px;left:0px;z-index:10000; width: 20px; height: 20px'> </div> <div id='lhContainerDiv' style='position:fixed;top:32px;left:0px;z-index:10000;width:800px;height:512px;overflow:auto;visibility:hidden'> <div id='gridDiv'/> <span id='lhClearButton'/> </div> <script src="/designer/localhistory.js" type="text/javascript"> </script> This will put that transparent white box on the top left corner of the editor frame. This 'solution' will be replaced by properly registering localhistory as a plugin of course :) There are some TODO-s and questions in the localhistory.js . Feedback is welcome :) I'll go on cleaning this up so that this can integrate nicely to the editor. cheers, Gabor On Thu, Oct 25, 2012 at 9:20 PM, Gábor Farkas <gabor.farkas(a)doctusoft.com&gt;wrote: > Hi, > Thanks for the ping, yes, I'd still like to contribute, it's just that > the company had some other priorities these weeks, but i'll find some time > to clean things up a bit. > There are some questions still: > > - *accessing*: I didn't yet scan the source to check how to put an > icon in the toolbar to display the local history panel.
