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. I guess the best approach will be to make this localhistory thing a plugin, so I can start by taking the servicerepo plugin as an example. For the prototype, I modified the editor.html and added a transparent div, and the panel shows up by clicking on that.

• when to create an entry: currently I check the json source of the model every 10 seconds, and if it's changed, I create an entry. Maybe this should be extended by somehow grouping these entries. For example, if the user keeps editing actively for two minutes, I keep only one entry, updating that entry every 10 seconds. But if the editing period is longer than two minutes for example, I keep one entry for each two minutes block. If the user edits for 30 seconds, then waits two minutes, then edits again, two entries will be created again. Something like this might be useful to keep the history reasonably small, but still quite useful and real-time.

• when entries expire: entries don't yet expire, so the local storage can get full after some time. You can delete all entries at once. I think we should add the possibility to delete entries individually, and to configure that after a specific time, entries are autmatically deleted. Or maybe, for entries older than one hour, we keep entries only in 5 minutes granularity, after two hours, every 1 hours, and one entry for each day older than 24 hours. Or maybe this is unnecessary for our scope ...

What do you think the best way would be to share the prototype with you? Well, maybe just emailing the files will be enough for now.

I'll try to clean up the source tonight and send you an initial version, so that you can take a look and try.

Thanks

Gabor

Hi Gabor, are you still wanting to contribute your work? Just checking in case you are waiting on anything from me in order to start.

Thanks.

Hi Gabor - that looks impressive and useful for the community. I'd be happy to work with you to incorporate this functionality into the Designer codebase and promote you as community contributor for jBPM. Let's chat on IRC (#jbpm or #jbpmdev on irc.freenode.net).

Hello,

We've created a prototype for a local history functionality for the jbpm-designer, we needed it for multiple reasons. It stores data in the browser localStorage, so it also serves a bit like 'undo after save'. It checks the json representation of the process every minute and if it differs, it creates a new local history entry, including a thumbnailed screenshot. It's available after browser restart too, so if you accidentally close the browser, you can still restore your work.

Here's a small screenshot.

Needs quite much elaboration, but it's already functional and useful for our needs.

If you find it interesting, we'd be happy to share it with the community.

regards,

Gabor Farkas
