Liferay 7 Repeatable Field in Structures not working

[7年前 に Siva Sai Krishna Paladugu によって更新されました。]

Hi,

I am trying to create new structure and template for Web Content. I am able to assign repeatable option to a field in the structure that I have created. But while trying to click "+" button for that field (i.e., trying to add another value for repeatable field) , I am getting error in console as follows:

Uncaught TypeError: Cannot read property 'getData' of null

Thanks for the quick reply.
Can you please help me in applying the patch?
It was mentioned in the thread that fix is provided in https://github.com/liferay/liferay-portal/commit/8d3f0b6daf85587ca457e13be6f81e163ed63676.
But I am not finding the way to apply this fix in my liferay server.

Thank you.
