Hi !
I reiterate because in fact the problem is not completely resolved.
```
from maya import cmds, OpenMaya, utils
def qd_handle_attr_cb(mp):
print mp.adString()
def qd_dirty_plug_cb(mo, mp, *args, **kwargs):
if OpenMaya.MFnAttribute(mp.attribute()).name() != 'fileName':
return
print mp.adString()
utils.executeDeferred(qd_handle_attr_cb, OpenMaya.MPlug(mp.node(),
mp.attribute()))
cmds.addExtension(nodeType='transform', longName='fileName',
dataType='string')
s_node_1 = cmds.createNode('transform')
s_node_2 = cmds.createNode('transform')
cmds.connectAttr('{0}.fileName'.format(s_node_1),
'{0}.fileName'.format(s_node_2))
msl = OpenMaya.MSelectionList()
msl.add(s_node_2)
mo = OpenMaya.MObject()
msl.getDependNode(0, mo)
i_call_back = OpenMaya.MNodeMessage.addNodeDirtyPlugCallback(mo,
qd_dirty_plug_cb)
# OpenMaya.MNodeMessage.removeCallback(i_call_back)
```
If I set* s_node_1.fileName* my callback is append but the value setted on
*s_node_2.fileName* is not valid. The attribute *s_node_2.fileName* has a
delay value.
You have solution for this case ?
