Dynamic description for the delete button/context menu [message #1237833] Thu, 30 January 2014 18:23 Go to next message

Hi all,

I wrote an XXXDeleteFeature and I would like to provide a dynamic description for the delete button / context menu option depending on the business object state of the selected picture element.

This way, I would have the possibility to give the user an explanation when deletion is not allowed (typically in case of a 'LOCK' state...).

I tried to dynamically process a description while executing #canDelete() so that #getDescription() would simply have to return it.

But, surprisingly, #getDescription() is executed before #canDelete().

Is this normal ? Any idea how I could achieve this dynamic display ?

Kind regards,

Laurent

Laurent,

yes, that's normal. The content menu entry is first added and then set to
enabled/disabled.

You could check the state already in getDescription and return and
appropriate text.

Hi Michael,

Thanks for the explanation about the internal cinematic.
And how can I get access to my business object (to check its state) in #getDesciption ?
This method doesn't have any IDeleteContext parameter like in #canDelete...

hm, right. That's a good point... :-(

Besides some dirty tricks, I only see the option for an enhancement of that
method. But I'm not sure if it is possible to provide the context
information in all cases, because the getDescription method is called from
various spots and at some the information on the context might not yet be
available.

Anyhow, would you file an enhancement request for that?

Thanks,
Michael
