Rhino, DynamicScope and Handlebars

[Maurizio Cucchiara]

Hi guys,

I'm trying to use DS and Handlebars together, but I didn't find yet a way to make it work.

I wrote down an example based on DynamicScopes.java which basically use Handlebars to compile a template (instead of a simple script).

This is the output I get from running the main class (which makes me think that there are some concurrency issues)

Running the script in a single thread

Hi Maurizio,

Did you manage to fix this? I'm running into a similar issue, and using my Google-fu, this is the only post I could find that seems to relate well enough to our error. Let me know!

Thanks,
