android activity - Activities are always collapsed in rehosted designer -

-

i'm trying rehost designer, every time slap workflow designer:

_workflowdesigner = new workflowdesigner(); // added ui here properties.content = _workflowdesigner.propertyinspectorview; _workflowdesigner.load(myworkflowinstance);

where myworkflowinstance workflow defined in referenced assembly. have done magic register default activity metadata registered:

new designermetadata().register();

and i've registered custom nativeactivities:

public static void register(ienumerable<type> activitytypes) {                 // activitytypes custom nativeactivities     // , workflows (root of system.activities.activity)     var builder = new attributetablebuilder();     var attrgroups =         x in activitytypes         y in x.getcustomattributes(true).oftype<attribute>()         group y x g          select g;      foreach (var typegroup in attrgroups)         builder.addcustomattributes(typegroup.key, typegroup.toarray());     metadatastore.addattributetable(builder.createtable()); }

yet, when load activity in designer get:

why r u collapsed?

what missing here?

i'm thinking has fact these workflows compiled , exist within implementation property of activity...

is workflow instance wrapped in activitybuilder?

update: investigating little further here found 1 possible solution using workflowinspectionservices.

var activities = workflowinspectionservices.getactivities(new demoworkflow()); designer.load(activities.first());
