Description
Dear Javier,
this was our first issue regarding the initial loading of CEP.
We have tried the last image of CEP on a new instance with Docker with all
possible browsers.
The UI Administration although is still slow, we have overcome it by having
a continuous open session on a VPS so regarding the question you could close
it as ticket as it escalated.
We had,and still have, a number of other issues since that, and we sent
another email from 24th of September on which we still have no answer
and all the problems that come with that in our development.
Below is the email from 24th of September, to let you aware of.
Regards,
Marios Protogiros

Activity
We tested the CEP on Chrome under Windows.
When I tried to recreate the bug on your CEP instance I used Chrome on Mac.
The IP or time should have no influence.
I will open a bug in our internal CLM that indicates your problem. Maybe the developers could recreate it.
Thanks,
Tali
Hello,
The below image is a screenshot of the CEP instance whose url is the one
you said the delete operation worked.
As I have tested myself again, the delete is not working.
Could you tell me on what browser,OS you made your testings?
We have tried numerous times on various browsers(IE,Firefox,Chrome)
,various operating systems(W2012 Server,W8.1,W7),and from various
locations(Greece,UK,Netherlands) and the delete is not working, among the
other issues I mentioned on my previous emails.
Is the CEP enabler Web UI dependent of the IP you are logging in or time of
action?

Marios Protogiros

The process of reporting a bug is to open a ticket as you did, preferably with a description of one bug only, and with a scenario that will allow us to reproduce the bug.
I just played with the CEP instance you sent, added two events and two consumers, saved the project, opened another project, got back to the initial one, deleted the first event and the first consumer, saved the project, opened another project, opened again the initial project and verified that the two deleted definition are indeed deleted.
So I couldn't reproduce the bug.
Best regards,
Tali Yatzkar Haham
I reopen this ticket since it holds activity.
I reassign it to Tali since questions are related to CEP.
Please Tali, remember follow the instructions at http://backlog.fiware.org/guide/tracker.html#email-issue to answer in a way Marios receive the input by email. Thanks.
Hi,
I hadn't received the JIRA ticket you mentioned, so thank you for
forwarding it.
Regarding your answers,
a)could you describe me the process of what I have to do to open a bug for
deleting a definition?
The scenario is,
create new project => create new event => right click the new event =>
select delete=> delete does not do anything.
You are most welcomed to test it on this instance,
http://185.23.171.81:8080/AuthoringTool/Main.html.
Please try to create a new project, and define some events, consumers ,
etc. and try to delete some of them, then save the definition
select another project and then reload it.
The only way of working with CEP , is through the REST Administration API,
where we post an updated definition.
Thank you
Marios Protogiros

Dear Marios,
I answer this questions, but you may didn't get it, so I'm trying again.
I already answered those issues in another ticket -
https://jira.fiware.org/browse/HELP-4894?filter=11607
FIWARE.Request.Lab.Data.CEP.BeeZon Issues using FIWARE-LAB and GE enablers
I guess you didn't received it. Below please find my answers:
Thank you for using the CEP GE, sorry you had your instance deleted.
As for your issues:
a) The delete definition option should work. In order to open a bug on it, please describe a scenario in which it doesn't
b) Again, I'm not aware of this issue. If you want us to open a bug for it, please send us the project definition and on which CEP instance you run it on (if it is based on an image, please send us the image name).
c) The save button updates the definition in the UI repository. It doesn't export it to the engine, and the engine is not aware on this update. You need to export it, and stop & start the engine to have it run with an updated definition,
d) We plan to add a more advanced sample.
e) The import should work. Beside that your steps are the right steps. You should export to a file for a back up, you should export the definition to the engine repository, you should update the engine to work with the saved definition (if you changed the definition name from the previous run), you should stop & start the engine to have it run with the new definition.

Hi,
we havent't any update from you regarding CEP.
Could you let us know if you are looking at the issues mentioned?

Hello,
Regarding CEP, these are the issues we are having with the CEP Web
Administration Tool.
a) The delete context menu does not work. E.g. deleting an event, or
consumer.
b) Importing a project from a previous saved definition does not render to
the UI. It remains empty ignoring the imported definiiong.
c) The save button also does not update the definition. If we select
another project and then reload the changes have not been saved.
d) There is not a complete tutorial of using the WebUI in a new CEP. There
are some video tutorials, showing glimpses of defining an event, EPA, etc,
but not an end to end scenario, and how to update the server of using the
new definition.
e)The only way, it was finally possible to use a new project was the
following;
1)create a new project, add the events, consumers,context, EPAs,
trying not to make any mistakes requiring to delete something.
2)export definition to a file for back up and then export
definition to server.
3)The only way we can change a definition is by the REST
Administration Api.e..g To alter the Url of a consumer, we have to use the
REST Administration API while it would be much easier to use the UI Tool.
We are using a CEP image from Fiware Cloud, but we have also build a
docker image with the latest version getting the same results as well.
Let us know if you want any more information.
Kind Regards

Dear Marios, Dear Javier,
Let me emphasize it's not clear to the GE Owner how to help.
Given we don't receive any input for several days, we're closing this ticket understanding you already overcome the difficulty.
Kind regards,
Manuel
Dear Marios,
Would you please summarize the issue for the GE Owner to understand how to try helping?
You can do it by replying to this email simply!
Thanks in advance!
Manuel
Hi Manuel,
honestly I'm not able to summarize this request.
I had only changed component from fiware-lab-help to fiware-tech-help (and I didn't assign the ticket) because it was a technical request addressed to Javier Romero (javier.romero@atos.net), but I didn't find this contact between Jira users.
I see that you assigned this ticket to the responsible of CEP component (I probably would have done the same ...)
Please, let me know what I have to do.
BR
Marco
Marco, will you please summarize what is the concrete request for the GE Owner? Thanks.
There is a lot of discussions in this ticket - I don't understand what I should refer to.
