SDK AE arbitrary params data flow

[ThomasT]

Hi, 
I have an arbitrary parameter where the user can draw two polygonal curves. 
So far it works a little. But I have trouble to get the arbH data correctly. 

It is created - ok. I get in in ClickEvent, the user clicks, a new point is addet (background: 1)
Parameter is PF_CHECKIN_PARAM. 
But then its disposed and copied again. 

ArbitraryCopyFunc SRC background: 0 foreground: 0  - OK, empty polygons 

ArbitraryCopyFunc DST after background: 0 foreground: 0    - OK 
LoadArbData background: 0 foreground: 0  - OK
SaveArbData background: 1 foreground: 0  <-- here the point was set
DisposeArbData background: 1 foreground: 0 <- it was saved, dispose get the changed one, but why dispose? 
ArbitraryCopyFunc SRC background: 0 foreground: 0 <-- but the next copy came and get the default one

And there are a lot of ArbitraryCopy events! Is this normal or a symptom of the problem. 

There is no error or exception. 

I need some explanations. 
If you need more Info I can give them. I am using smart render approache if that does matter. 

Thank you
Thomas

Hi Thomas,

Thanks for the post. I'm glad your marked it appropriately as SDK. That means that the proper product team member or Adobe Expert will come along and assist you as soon as possible. Sorry that I have to ask for your patience on this. I hope we can help you shortly.

Thanks,
Kevin

Hello?!? 
Please help. I am stuck. 

[ThomasT]

The problem is that AE does not recognize the changes I made. So the next copy is from the default. And my handle is disposed.

Because noone wanted to help me I post my solution for others. 
To get AE to accept the changed data I create a new handle and copy the data. 
Then it works and AE accepts the changed data.

PF_Err TTAEPluginParamStruct::EventClick(PF_InData * const in_data, PF_OutData * const out_data, PF_ParamDef *params[], PF_EventExtra	* const event_extra) {
  PF_Err err = PF_Err_NONE;
  //select the param to be drawn
  TTAEPluginParamDiagram* const diagram = GetArbitraryParam();
  if (diagram) {
    //get data first and set into param 
    AEFX_SuiteScoper<PF_HandleSuite1> handleSuite(in_data, kPFHandleSuite, kPFHandleSuiteVersion1); 
    
    PF_ParamDef	aeParamDef;
    ERR(PF_CHECKOUT_PARAM(in_data, diagram->Numberation - 1, in_data->current_time, in_data->time_step, in_data->time_scale, &aeParamDef));
   // PF_Handle	arbH = aeParamDef.u.arb_d.value;
    PF_Handle arbH = params[diagram->Numberation - 1]->u.arb_d.value;
    
    if (arbH) {
      ArbData* const data = reinterpret_cast<ArbData*>(handleSuite->host_lock_handle(arbH));
      if (data) {
        diagram->LoadArbData(data);
        diagram->Click(in_data, out_data, event_extra);
        diagram->SaveArbData(data);

        const size_t size = handleSuite->host_get_handle_size(arbH);

        PF_Handle newH = handleSuite->host_new_handle(size);
        void* newData = handleSuite->host_lock_handle(newH);
        std::memcpy(newData, data, size);

        handleSuite->host_unlock_handle(newH);
        handleSuite->host_unlock_handle(arbH);

        LogHexDump("TTAEPluginParamStruct::EventClick", data, 20);

        params[diagram->Numberation - 1]->u.arb_d.value = newH; 
        params[diagram->Numberation - 1]->uu.change_flags |= PF_ChangeFlag_CHANGED_VALUE;

        event_extra->evt_out_flags |= PF_EO_HANDLED_EVENT | PF_EO_UPDATE_NOW;
        out_data->out_flags |= PF_OutFlag_FORCE_RERENDER; 
        aeParamDef.uu.change_flags |= PF_ChangeFlag_CHANGED_VALUE;
      }
    }
    event_extra->evt_out_flags |= PF_EO_HANDLED_EVENT | PF_EO_UPDATE_NOW;
    Logger::getInstance().println( "CHECKIN_PARAM arb handle = " +std::to_string(reinterpret_cast<uintptr_t>(aeParamDef.u.arb_d.value)));
    ERR(PF_CHECKIN_PARAM(in_data, &aeParamDef));
  }
  return err;
}
