How to define custom DITAMapTreeDropHandler as a wrapper to default one ?

[Vince]

Hello,
I want to define a custom DITAMapTreeDropHandler to perform some URL operations before call the default one.
Is it available ? how to do this ?

To be more precise, my need is to benefit from AuthorNode schema aware selection of default map tree handler.

Thanks a lot

Hi Vince,

So you already used our API "WSDITAMapEditorPage.addDropHandler(DITAMapTreeDropHandler)" to register your own tree drop handler, right?
And on the "consumeDropURLs" callback you can either decide to handle this event yourself or to return "false" and let Oxygen handle it.
I'm afraid you do not have the means to directly call the code Oxygen would perform if you return "false".
You have access to the "WSDITAMapEditorPage.getDocumentController()" to insert your own topic refs.
