Hi folks,
I have a simple tag with a dynamic combobox which gets filled in GetDdescription. Like this:

  
Bool ModelMetaDataTag::GetDDescription(GeListNode* node, Description* description, DESCFLAGS_DESC& flags)   
{   
     if (!description->LoadDescription(node->GetType())) return FALSE;   
  
     std::vector<String> items;   
  
     BaseContainer *descbase = description->GetParameterI(DescLevel(1001),NULL);   
     if (descbase) {   
          BaseContainer *listBc = descbase->GetContainerInstance(DESC_CYCLE);   
          if (listBc)   
          {   
               listBc->FlushAll(); // clear combobox   
               for (size_t i = 0; i < items.size(); ++i) {   
                    listBc->SetString((LONG)i, items[i]);   
               }   
          }   
     }   
  
     flags |= DESCFLAGS_DESC_LOADED;   
     return SUPER::GetDDescription(node, description, flags);   
}

When I have this tag selected and then perform a clone of the document and insert it then the combobox of the tag will be empty and I need to rebuild it by deselecting and activating it again.
For the mentioned procedure I use these python commands:

  
docClone = doc.GetClone(c4d.COPYFLAGS_DOCUMENT)   
c4d.documents.InsertBaseDocument(docClone)

Now the question how can I restore the content of the combobox immediately when the cloned document gets inserted?
Best regards,
Satara

Have you tried setting the DIRTYFLAGS_DESCRIPTION on the tag?

Thanks, totally forgot about that flag. It seems to work, but it does appear empty for a short time. Is it possible to fill the container outside of this function? Shouldn't it be filled already, when the document is just cloned?

Hi Satara,

can you put a debug print in GetDDescription() and check if it is called once before the correct items are
filled in the description?

Thanks,

Yes it gets called. I have to change the way the list of items gets generated. Thanks for your help.
