OOTB portlets instanceable

[12年前 に Priyanka Dhingra によって更新されました。]

Hi,

I know the we can make out out of the box portlets instanceable by manually editing ROOT/WEB-INF/liferay-portlet.xml
but my problem is that when we'll upgrade to some other version it would be a problem and since there are licensed version of liferay also we cannot modify the aforesaid xml file just like that.

So, is there any other way I can make any OOTB portlet instanceable or non-instanceable.(like hooks or something else)

Any help would really be apprecaited.

Thanks in advance
Priyanka

Hi Priyanka Dhingra,

For this you have to override liferay-portlet.xml to liferay-portlet-ext.xml by using ext, and change portlet <instanceable> tag.

The real question is why would you want to do this?

Instantiable controls whether you can have only one instance of a portlet on a given page or whether multiple instances per page are allowed.

For example, web content can be on a page multiple times, and that makes sense. Each one can contain different content, so they are each separate instances.

Mail on the other hand only makes sense to have a single instance on a page (yes, users can have multiple mail accounts, but all of the accounts listed in separate mail portlets on a single page would be pretty confusing).

For all of the Liferay portlets, I think they've done a pretty good job determining which ones can be multiples and which ones should allow only a single instance.

So it gets back to the question, why would you want to do this?

Hi David,
This was a question asked to me. I knew the method i mentioned in post but was trying to see if any better alternative available.. I am a Liferay beginner so there is a possibility that the solution I am trying may not be always efficient.

Thanks

Hi,
I think that the "instaceable" behavior of a portlet is tightly coupled with its business logic. Are you sure you want to change this setting? Are you referring "instanceable" as the ability to add a portlet instance to a portal page?

You're talking about modifying just the settings and not the source code.
