diagramTypeProvider must not be null

[Former Member]

Hi,

When following the openSAP "Introduction to SAP Hana Cloud Platform", Week 2, Unit 1, working on Eclipse on my machine (Windows), I am stuck at the step "open diagram" in the JPA Content (in the Project Explorer Menu) :

the error diagramTypeProvider must not be null shows up.

I have already checked that the JPA diagram editor is well installed.

-> Do you have any advice  to solve this issue ?

Thanks in advance,

Maxime

Diego Gabriel is correct.

Go to Help > Install New Software and enter http://download.eclipse.org/graphiti/updates/0.11.4 as the site. Install Graphite, reboot eclipse and try to open the diagram once again.

Hello Maxime,

Are you using Eclipse Mars?

If yes, there is a bug with this version. Take a look

here

and here

https://bugs.eclipse.org/bugs/show_bug.cgi?id=472835

Please try to use Eclipse Luna or the workaround indicated in the link. It should work properly.

Please let me know the results and reward if the answer was helpful.

Regards,

Diego Gabriel
