Hi,
i have a real strange issue here and i have no clue what is causing it. i cannot convert my pluginobject into a polygon object . it remains the plugin object.

what could be responsible for this??

thanks,
ello

this happens when you return NULL.

hm, but i only return NULL if the plugin doesnt have the correct settings applied (for example if there is no child object)
the object returns something other than NULL, since otherwise i wouldnt see the result in the editor??

cheers,

No, this only tells you that you see it in the editor. This doesn´t have to necessarily mean it correctly returns something on conversion where the caches are probably recalculated to get a purely fresh representation of its state. Therefore it may be possible that something happens which makes your object retun NULL. I don´t see any other chance why you wouldn´t be able to convert your object otherwise. As soon as you return something it can be converted. That is my educated guess.

You can easily find out by starting a debug session to find out the real culprit though.

thank you.. it seems that it had something to do with the DependenceList.

it works now, and as a positiv sideeffect some other issues went away, too

hi again, i have a similar issue again. i cannot convert the plugin object if one of the linked objects is above the plugin object in the object-manager.. but i dont have an idea why this is so. anyone knows a solution?

a brutal method would be to move the linked object below the plugin object via script. but i think thats only the last way i'd go..

thanks for any input
cheers,

I assume you do something like this?

BaseObject *YourPlugin::GetVirtualObjects(PluginObject *op, HierarchyHelp *hh)   
{   
     BaseObject *ret = NULL; //This is where your objects go...   
        
     Bool dirty = op->CheckCache(hh) || op->IsDirty(DIRTY_DATA);   
     if (!dirty) return op->GetCache(hh);   
        
     BaseContainer *data = op->GetDataInstance();   
        
...

more or less, yes.. but somehow this is related. i tried out to place those lines at the beginning and at least the converting works. the dependenceList doesnt work anymore, but maybe i can solve this now.

thanks..
