How to Execute a Modifier plugin in Expression priority

[chuanzhen]

Hi,
I have created a object modifier plugin and I want it to work once in priority Expression 10, and then again in Generator 1. How can I make it work as expected?
In the code, AddToExecution() and Execute() do not seem to work (the documentation states that switching priorities requires calling these two functions).

import c4d
from c4d import plugins, bitmaps


PLUGIN_ID = 1000001

class S_Temp(plugins.ObjectData):


    def Execute(self, op, doc, bt, priority, flags) -> int:
        print("Execute")
        return c4d.EXECUTIONRESULT_OK

    def AddToExecution(self, op, list) -> bool:
        print("AddToExecution")
        return True


    def Init(self, node, isCloneInit: bool) -> bool:
        self.InitAttr(node, c4d.BaseList2D, c4d.S_TEMP_POSEDTARGETS)
        self.InitAttr(node, c4d.BaseList2D, c4d.S_TEMP_POSEDSOURCEADD)
        self.InitAttr(node, c4d.PriorityData, c4d.S_TEMP_PRIORITY)

        if not isCloneInit:
            pridata = c4d.PriorityData()
            pridata.SetPriorityValue(c4d.PRIORITYVALUE_MODE, c4d.CYCLE_EXPRESSION)
            pridata.SetPriorityValue(c4d.PRIORITYVALUE_PRIORITY, 10)
            node[c4d.S_TEMP_PRIORITY] = pridata
        return True

    def ModifyObject(self, mod, doc, op, op_mg, mod_mg, lod, flags, thread):
        allp = [pos + c4d.Vector(0,100,0) for pos in op.GetAllPoints()]
        op.SetAllPoints(allp)
        op.Message(c4d.MSG_UPDATE)

        return True


if __name__ == '__main__':
    plugins.RegisterObjectPlugin(id=PLUGIN_ID, str="S_Temp", g=S_Temp, description="stemp", info=c4d.OBJECT_MODIFIER,
                                 icon=None)

Here is the file of this plugin --> s_Temp.zip

Thanks for any help!
