including self-developed portlet with <portal:runtime>

[Stefan Finke, módosítva 8 év-val korábban]

Hello,
I'm trying to include a (simple) portlet into another by <portal:runtime>.
Including built-in protlets e.g. Language Portlet succeeds. But including my own self-developed portlet results in rendering error with following stack trace:

Can you try checking these two things?:

• Remove <ajaxable> from liferay-portlet.xml for both portlets
• Try with 6.2 CE GA5

If that doesn't work, please attach here that sample portlet..

Thanks!

Hello Juan. Thank you for your quick reply.

I removed <ajaxable> tag and installed Liferay 6.2 CE ga5.
I also removed some needless (primefaces) dependencies from my project.
Tried again. No effect.

So I attached my sample project's archive...

Hi Stephan,

thanks for the sample portlet. Vacation days in Spain until Wednesday. Will check this then.

Hi Stefan,

thanks again! I could reproduce the issue and created a new ticket: https://issues.liferay.com/browse/FACES-2527.

Meanwhile, as a workaround, can you separate both include and "parent" portlets as different portlet projects? This way works fine. BTW, when naming a project don't include "portlet" in it's name, as that is used by Liferay to differentiate plugin types. All text after "-portlet" will be ignored.

Thanks!
