I have an expression tag, and would like to make changes on a description during the Message method.
I catch the MSG_DESCRIPTION_CHECKUPDATE message. So far, so good...

Here's my question:

How do I get the BaseContainer of my description in this method? Reading to a couple of posts I found that it could have to do with DescriptionCheckUpdate->decsID, but the documentation misses a lot of background how this is suppose to work.

Any help would be appreciated.

Thanks!

Ok, resolved...

  
Bool MyPlugin::Message(GeListNode *node, LONG type, void *data)   
{   
     switch (type)   
    {   
        case MSG_DESCRIPTION_CHECKUPDATE:   
        {   
               BaseContainer *bc = ((BaseList2D* )node)->GetDataInstance();   
               if (bc) {   
  
                    ...do whatever you have to do...   
  
               }                  
          }   
     }   
     return SUPER::Message(node, type, data);   
}
