Davide, I've just tried my Google Maps Widget Thingworx application from within my VM and it worked fine, but when accesing from outside, it keeps failing. There is where you need to get an API Key from Google in order to get to work fine, wich is pretty fast and simple.
Hope this could help.
I can, but with support.ptc.com (and not thingworx.ptc.com)
Alternatively, Go to your ThingWorx composer -> Help -> Documentation and search for Google Widgets.
My Google Map's problem is InvalidKeyMapError.
as suggested by some of you, i have inserted the key in the extension's metadata file.
I restarted tomcat and reistalled the extension several times but continues to say that the key is not valid.
Can anyone help me??
Thank's a lot!!
I have tried making changes in metadata.xml as per above mentioned instruction, then re-imported it but still facing problem.
Did some one got fix to this issue?
