Issue upgrading from 5.17 to 5.19.0.2

Hi,

I am trying to upgrade from 5.17.0 to 5.19.0.2. After updating the version in our POM for "activiti-webapp-explorer2", "activiti-engine", "activiti-explorer" & "activiti-ldap", I deployed the application in my local STS Pivotal TC. Here are the issues I am facing:

1. Activiti Modeler isn't working correctly. A blank page shows when I attempt to create or edit a model. Using Chrome version 45.
2. Under Processes –> Deployed Process Definitions, I am unable to view the Process Diagram. It shows blank.

I have checked the tomcat logs but didnt find any thing that could give a clue. Schema version in ACT_GE_PROPERTY shows as "5.20.0.1". Not sure why it isnt showing 5.19.0.2.

Appreciate any pointers on how to go about checking for clues.

Thanks,
Srini

Update:

1. I dropped the Activiti Schema
2. Started Activiti-Explorer 5.19.0.2. It created all the schema objects by running activiti.oracle.create.engine.sql, activiti.oracle.create.history.sql & activiti.oracle.create.identity.sql.
3. Version in act_ge_property table is 5.20.0.1
4. Same issue with Activiti Modeler (blank editor)

Update 2:

1. Rolled back to 5.17.0 (5.19.0.2 –> 5.19.0 –> 5.18.0 –> 5.17.0) by doing a fresh install everytime!!
2. 5.17.0, things start to work again
3. Upon going back to any version above 5.17.0, Chrome Debug Tool reveals the following:
"GET http://localhost:8080/activiti-explorer/service/model/1/json 403 (Forbidden)"
4. In 5.17.0, i don't see any such issue and the json is accessible.

Will continue to dig into it. Anyone else running version > 5.17.0?

Update 3:

1. The model is present in the DB. Not sure why access to it is forbidden.
2. Issue present in Chrome 45 & FireFox 38 (a similar issue is called out in the release notes quoted below)
3. Access Log from localhost tomcat ("GET /activiti-explorer/service/model/1/json HTTP/1.1" 403 1054)

From Release Notes:
Known issues

There's a known issue with Chrome and the Activiti Explorer / Vaadin 6. You can get a blank screen in the details part of the Explorer. This is a known issue for Vaadin 6 and Chrome 43 and 44. There are bug fixes under way with Chrome 45, so that might fix it. Other browsers like Firefox work fine.

I've tried running the 5.19.0.2 here … but here it just works (Mac, Chrom v 48).

Thanks for confirming. Not sure what is going on here at my end with access and 404 issues. Here is the log after upgrading to Chrome 48.

wow that's very odd … the blank page was a known … but the 403 is new … and I don't see how that could be releated to the server.

I see you're running Pivotal… does the same happen with a vanilla Tomcat?

Update: Issue Resolved

We had implemented a custom LoginHandler which was not setting the AUTHENTICATED_USER_ID (_currentUser) on the Session. Due to this, ExplorerFilter was unable to authenticate incoming requests directed to "/service" and was returning a 403.

This check in ExplorerFilter was introduced in 5.18 and not before.
