yes this could be, ivy.html works only with an ivy context and when a http-request is available. But without a stacktrace/error message is hard to guess...

Can it be that the issue is because my process is executed asynchronously ?

Please send us the full error message with stacktrace, you find it in the log (<server install="" root="">/logs/...).

What is PMV ?

The interesting part is that using ivy.html.startref("Start Processes/DashboardPages/DefaultApplicationHomePage.ivp") in HTML Dialog it is working correctly, if I use it server side, both in Java and Ivy Script - it is trowing an error.

the version of the server is 6.2 and the version of the deployed application is 6.1.

I guess that the deployed projects / PMVs are not equal. Maybe the engine application does not contain all projects from the design time? Can you attach the concrete exception that is thrown?

Answers to: ivy.html.startref throws exception on server
