Blank Modeler Editor Screen

I've deployed the 5.11 WAR files to Tomcat and can use most of Activiti Explorer without any issues. The one thing I can't seem to get working is the ability to edit a model using Activity Explorer. If I create a new model, or try and edit the demo model, all I see is a blank screen when I click o

Hi Bill,

A couple of questions to get more info:

- Do you get Javascript errors?
- Do you see an error in the Tomcat log?
- Are you using the in-memory H2 database?

Best regards,

After deploying the applications to a different Tomcat server, the editor is now working.

Thanks for the pointer. I'll look through the Tomcat log on the other server to see what's missing.

Hello,

if you are you using Tomcat 5 I know the issue.
I had this problem on Tomcat 5 and not on Tomcat 7, so I guessed it was a tomcat context issue.
In fact, after some struggles, I found out a solution modifying the server.xml of Tomcat5 creating 4 context, one for each folder that is served as static content.

Copy the following text inside the host element of your server.xml (normally you use the localhost) and replace <deploydir> and <workdir> with your dirs:


 <Context docBase="<deploydir>\activiti-explorer\libs" path="/activiti-explorer/libs" reloadable="false" workDir="<workdir>\activiti-explorer" crossContext="false">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" />
 </Context>
 <Context docBase="<deploydir>\activiti-explorer\api" path="/activiti-explorer/api" reloadable="false" workDir="<workdir>\activiti-explorer" crossContext="false">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" /> 
 </Context>   
 <Context docBase="<deploydir>\activiti-explorer\editor" path="/activiti-explorer/editor" reloadable="false" workDir="<workdir>\activiti-explorer" crossContext="false">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" />
 </Context>
 <Context docBase="<deploydir>\activiti-explorer\explorer" path="/activiti-explorer/explorer" reloadable="false" workDir="<workdir>\activiti-explorer" crossContext="false">
  <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1" />
 </Context>

Restart Tomcat

Hope this helps!
Bye

There is indeed an issue with glassfish with the 5.11 release, which was fixed on master right after the release.
The answer should be somewhere on the forum though.
