list1 is my combobox

@bwsounds I don't think the expansionCallback is triggered when you set the currentExpansion to "". You should test it to see if that is the case.

@d-healey
humm, still having the same issue.

d.healey

@bwsounds Need to see some code to know what you're doing. Does the expansion callback trigger?

I removed the "currentExpansion to" but The factory samplemaps still wont populate in the combobox after previously selecting an expansion.

// // // E X P A N S I O N // // //
const var expHandler = Engine.createExpansionHandler();
const var expansions = expHandler.getExpansionList();

expHandler.setAllowedExpansionTypes([expHandler.FileBased, 
                                    expHandler.Intermediate, 
                                    expHandler.Encrypted]);
const var expansionNames = [];
expansionNames.push("FACTORY");

for(e in expHandler.getExpansionList())
   expansionNames.push(e.getProperties().Name);



const   Sampler1 = Synth.getSampler("Sampler1");

const list1 = Content.getComponent("list1");
list1.setControlCallback(onlist1Control);


const var namesExp = [];


var sampleMaps   = Sampler.getSampleMapList();
var sampleMapsed = Sampler.getSampleMapList();

inline function newcombobox(newExpansion)
{

      if(isDefined(newExpansion))

   {
       local cx = expHandler.getCurrentExpansion();
       sampleMaps = cx.getSampleMapList();
       sampleMapsed = cx.getSampleMapList();
       local expansionProps = cx.getProperties();
       local expName = expansionProps.Name;


       list1.set("items", "");
       list1.set("items", sampleMapsed.join("\n"));
     
   }
   else
   {
   
      sampleMaps = Sampler.getSampleMapList();
      list1.set("items", "");

   }
}

expHandler.setExpansionCallback(newcombobox);

newcombobox(undefined);






inline function onlist1Control(component, value)
{
	if (value > 0)
	{
		local sampleMap = component.getItemText();

		if (sampleMap != "")
		Sampler1.loadSampleMap(sampleMap);		
			
	}		
}


list1.set("items", sampleMaps.join("\n"));
list2.set("items", sampleMaps.join("\n"));

Does the expansion callback trigger when you deselect the expansion and return to the "factory" setup?

DanH

@bwsounds You're selecting expansions / factory etc through the preset browser, right?

d.healey

@danh He has a combobox

yep

originally yes, but i switched to a combobox as I thought it would help me with this issue.

d.healey

@bwsounds In your expansion callback you are checking if newExpansion is defined, when you revert to the factory setup newExpansion will be "" which is also defined, so you won't hit the else clause.

BWSounds

@d-healey
ahh makes since.

BWSounds

@d-healey @DanH
ok thank you guys for your help, last question.

Does if make a difference whether I use a expansion install script to install the expansions or just add a button to the interface that opens up a browser window to the expansion folder and let the user drop the expansion in there?
