Re: [Dev] [IOT]Concerns regarding saving the image and binary files in the File System

[Chathura Ekanayake]

As Charitha and Waruna mentioned, we will have to implement the storage
method as an extension, where it is possible to switch among local file
system (with rsync), FTP, S3, etc based on deployment requirements.

@ChathuraD: We will not be exposing the actual storage to outside and all
accesses will be through IoT server APIs. In that case, do we need to
enforce security by having random file names in the storage? Regarding
possible optimization in image access, we can have
1) caching for frequently accessed images (which is independent of the
underlying storage)
2) separate fast access storage for images
Only if the latter is practical in real expected deployments, I think
option 2 mentioned by Megala is useful. Otherwise I prefer option 1.

Chathura

[Dev] Editing scopes in API manager

[Chathura Ekanayake]

Is there a way to edit existing scope details? I think it is useful to add
or remove authorized roles in a scope. One problem in editing scope details
is that it could make currently issued tokens inconsistent with the
authorization policy. I think we can handle that by invalidating all issued
token upon a scope change.

Re: [Dev] [Gsoc2016] [PC] Web (Javascript / D3) based BPMN editor to support a subset of commonly used BPMN constructs

Hi Heshan,

It looks good so far.. However, there are few fixes to be done.

- Properties box cannot be closed.
- Circles in bending positions of edges have to be shown only when mouse

- Gateways should allow multiple connection points (at least 4)

Re: [Dev] Shipping a pre-populated db with samples in Process Center.

[Chathura Ekanayake]

Yes, it is helpful to have a collection of samples for PC. PC has an
import/export feature where processes and related artifacts can be exported
into an archive and imported later. One option is to use this feature to
ship a set of samples. Some other process repositories are also using
similar methods to ship samples.

 Hi all,

 I am working on developing BPMN explorer ui using Unified UI Framework.

 The existing BPMN explorer ui is for BPS which has built on C4 and it
 is used Jaggery. So, I am working on BPMN explorer ui for BPS which is to
 be released on C5.

 We need to implement business logics in backend. For example, I need to
 send request to backend from browser, and from backend to BPS. Is there
 functionality to achieve it in UUF?

 Any idea on this is appreciated.

Re: [Dev] [ES][PC] Prevent automatic redirection in form submission in Process Center

[Chathura Ekanayake]

Hi Sameera,

Some fields supported by this search feature are not included in RXT. For
example, a process can have associated PDF files and the input provided for
the "Document content" field should match content of such PDF files (using
a Lucene based search). Therefore, I think the default advanced search
feature provided by ES cannot be used here.

Hi Dilini,

How are you fetching information about tasks in the current implementation?
Activiti REST API provides support for fetching task related information.
If we don't have it currently in our new REST API, we can add similar
methods to it.

Re: [Dev] [BPS][DAS] Sorting feature and range faceting for the aggregated records

[Chathura Ekanayake]

Hi Gimantha,

Instead of getting record counts, is there a way to get aggregates of some
numerical field with range faceting?

Also, it would be useful to specify ranges as start value, end value and
gap, in addition to the method mentioned in the sample.

Regards,
Chathura

Re: [Dev] Displaying claimable user tasks in BPMN explorer

[Chathura Ekanayake]

Hi Amal/Shiva,

Yes, let's create a "Claimable tasks" tab.

I already created a jira to report this on last Friday:
https://wso2.org/jira/browse/BPS-656
So we can refer to this from the new jira (or keep only one).

Regards,
Chathura

Currently the BPMN explorer displays only the tasks "assigned" to the
logged in user. But it does not display tasks if the current user is a
candidate user or in a candidate group. Did we plan to implement this in
the explorer?

I think we should have a separate tab for claimable tasks, which shows
tasks assigned to both candidate user and candidate group. WDYT?

Hi Amal,

2nd graph shows the total number of active, suspended, etc task instances.
Should we show these details per task?

Re: [Dev] BPMN UI Stats page

[Chathura Ekanayake]

Hi Amal,

Can we have a list for human task vs task instance state (i.e. Task name |
# active | # completed | # failed | # suspended ).

Also, once we click on a task, we can list instance details of that task
(e.g. created on, current assignee, etc.)

Regards,
Chathura

Re: [Dev] Jaggery Human Task UI for BPMN

[Chathura Ekanayake]

Hi Amal,

I had a chat with Cyril at WSO2Con and he is willing to give feedback on
our operational BPMN UI. Below are some initial comments from Cyril, which
were given in a previous email:

- only people that can launch (have the right Role) processes can see the
starting UI or even the complete definition
- plain Actors can only see their tasks (You can also have the tasks of "my
group" or "all-tasks" if allowed)
   in BPM, work lists like that are usually to be linked with organization
based rules (who can do what, who is to be assigned, etc).
   some customers even want users not to choose any task but to deal with
the "next" one (chosen by the BPM rules)
   some customers will want to allow the "assign to someone-else-in-group"
or not, etc.
   Usually, Work-Lists that are contained in plain administration console
cannot answer this real operational  need --> hence the creation of
operational consoles
- one could only need to see a read-only version of the process/task.

We may have to allow administrators to customize the operational UI to
facilitate some of the above requirements (e.g. display only the next task
vs. display all available tasks). Let's develop the first version to
support all functions provided by Activiti user tasks. Then we can add
features to configure/block certain functions for specific deployments.

We can have a call with Cyril once we get an initial version of the UI.

Regards,
Chathura

Re: [Dev] Activiti Clustering

[Chathura Ekanayake]

Hi Amal,

BPMN deployer in BPS maintains information about tenants' deployments in
memory. Therefore, we have to extend the BPMN deployer to replicate this
information among all members of a cluster.

There are TODOs in the code to indicate the places where such replications
have to be done. I think we can use two approaches for this:

(1) Replicate information using messages
(2) Use distributed hashmaps to store tenant information

Azeez/Sameera: Can you recommend which method should we use?

Chathura

[Dev] Extension for BPMN deployment archives

[Chathura Ekanayake]

Hi All,

Activiti uses archive files with .bar extension to package BPMN deployment
artifacts. These are just zip archives renamed to .bar extension.
Should we use the same extension in BPS, or should we go with .zip
extension?

We can change the extension to .zip (if required) in the BPS runtime (i.e.
.zip files containing bpmn files can be deployed in BPS). But Activiti's
Eclipse based BPMN designer produces .bar files, which cannot be deployed
as it is in BPS if we only support .zip files.

Thoughts...

[Dev] BPMN support - current state and next steps

[Chathura Ekanayake]

Hi All,

Myself and Amal have been working on implementing BPMN support in BPS based
on Activiti. Below is the status of this work, and immediate next steps:

Activiti engine and REST API integration - Done
BPMN deployer - Done
Admin services for BPMN features - Done
Admin UI - Done
Muti-tenancy support - In progress

BPMN editor - Planning to allow users to download the Eclipse-based
Actitivi editor, until we come up with a long-term solution
Clustering support - TODO
Jaggery based UI for end-user related functions - TODO
Async service invocation support - TODO

We are planning to do a M1 release of this by the end of this month with
the currently completed features (i.e. without multi-tenancy, clustering
and jaggery based UI).

Note: As the M1 release will not have a Jaggery based UI and we have
decided not to implement end-user related functions in the Admin UI, there
will not be UI support for some functions in M1 (e.g. browsing, claiming,
completing user tasks). Therefore, such functions have to be done using the
REST API.

Re: [Dev] Exposing the Activiti REST API

Hi Sagara,

If we deploy it as a web application, is there a way to access OSGi

As we don't package it as a bundle, a BundleContext object is not available

there a way to deploy a webapp as a bundle?

[Dev] Exposing the Activiti REST API

[Chathura Ekanayake]

Hi All,

Activiti has a Restlet based comprehensive REST API to expose all BPMN
related functions. As we are planning to have a REST API for BPMN, we can
integrate this Activiti REST module in Carbon. Could I get feedback on the
following items regarding this integration:

Restlet vs JAX-RS:
Should we integrate the Restlet based Activiti API or should we write a new
JAX-RS based REST module? I think it is better to use the Activiti REST
module as it allows us to migrate easily with new Activiti versions.

Integrating the Activiti Restlet based API:
If we decide to integrate the Activiti REST module, we have to expose the
Restlet servlet to handle REST requests. One option is to register this
servlet in repository/conf/tomcat/web.xml, which exposes this on the same
port as admin services. However, we have to keep these servlet registration
entries in the web.xml, even though the BPMN component is not deployed.
Another option is to start a separate server (if this is possible in
Carbon) for Activiti REST and register the Restlet servlet in that server.

Thoughts...

Chathura

Re: [Dev] Implementing BPMN support in BPS : Instances lost after server restart

[Chathura Ekanayake]

Hi Amal,

The default configuration in Activiti uses an in-memory H2 database. Data
can be made persistent (across server restarts) by changing this to a
disk-based DB. Change the database config in activiti.cfg.xml file to do
this. Currently BPS also uses the same XML (until we change it to use
bpmn.xml).

REST API as the remote interface for BPS BPMN. However, we have to filter
this REST API to make it tenant-aware.

- BPMN editor:
Both editors provided by Activiti are GPL licensed. So we have explore
other options such as the jBPM eclipse plugin.

[Dev] Adding new classes to the classpath of a bundle at runtime

[Chathura Ekanayake]

Hi All,

BPMN supports Java service tasks, which can execute Java classes within a
workflow. However, Java classes referred in these BPMN tasks has to be in
the classpath of Activiti.

Therefore, when a BPMN archive containing Java service tasks is deployed in
BPS, we have to put its Java classes into the classpath of the Activiti
bundle. Is there a way to do this? Is there a code that has already
implemented a similar scenario?

Thanks,
Chathura

Re: [Dev] UI support for BPMN

[Chathura Ekanayake]

Hi Amal,

We should also have a UI for listing deployments, which is the unit of
deployment in Activiti. A deployment can contain multiple process models
and other artifacts. In the deployments UI, we can add buttons to undeploy
deployments, which in turn undeploys all associated process models.

In the User Tasks UI, we can have buttons to claim, complete, comment,
delegate, etc. individual tasks. I think is better to have a separate UI
for individual tasks, which contains these operations.

Regards,
Chathura
