Command: Link to KM folder - does it exsist/workaround

[Former Member]

Hi,

We have a KM folder where we store articles based on xml forms. One iView displays the last 3 articles from this folder.

Is there a command that can be used in the collection renderer for creating a link to this KM folder and display the content with a selected layout set? The goal is that the user should be able to view all the articles in the folder. Is there maybe another work around? Any pointers?

Best,

Bjorn

Hi,

This is possible by implementing a UICommand, which will again call a KM Navigation IView with a specific layoutset.

So the link should look like this:

"/irj/servlet/prt/portal/prtroot/com.sap.km.cm.navigation" + "pathToKMFolder" + "?rndLayoutSet=YourSpecial_LayoutSet"

This link should be called in your UICommand.

Thx,

I know the links to my KM folders, but how do I implement the UI Command? Witch Java Class and parameters to use?

Looking forward to implementing this

Hi Bjørn,

In order to get the knowledge on how to implement a UI Command you can check out following links:

https://media.sdn.sap.com/html/submitted_docs/nw_kmc/howto/km/flexui/Flexible%20UI%20Components.html...

and

https://media.sdn.sap.com/html/submitted_docs/nw_kmc/howto/km/flexui/Implementing%20Flexible%20UI%20...

Hope this helps,

Robert

OK, I see I have to start programming again.... /me fingers crossed

Hopefully I'll have this ready by the end of the week......

So there is no java class ready for this (as in the example you linked to)?

Hi Bjorn,

I had the same requirement and this is the code that i used...

I got this from SDN only from Thilo's How to Guide...

I tried to find that link...

Hi,

The code from BP, should work.

The implementation where you should set your layoutset is in getLinkAttributes() method.
