New WorkSpaceTool tool does not see the operator from addon

Archive Python API

I have made simple scale active object addon, that supposed to use new WorkSpaceTool tool system. Problem is the new tool, does not see the test_scale operator from:

bl_keymap = (
        ("mesh.test_scale", {"type": 'LEFTMOUSE', "value": 'PRESS'} ),
    )

Only after reloading addons with F8 (bpy.ops.script.reload()) it starts to work (when new tool is selected, LMB click scales the active object).
Any ideas why MyTool won’t load the “mesh.test_scale” correctly when blender is started? Here is the python addon file

Is the tool not there in the toolbar, or is just the tool shortcut not working?

Tool is registered ok. If is use existing (build in) operator in bl_keymap - for the tool, it also works ok.
It is just if bl_keymap uses operator defined in the addon itself, then tool icon won’t work (icon is there, but does nothing, unless I reload all addons). It may be blender bug I think.

Can confirm the same is happening to me. Should be a bug then, would be great if you can report it via the Help -> Report a Bug menu in Blender.

Last post is from 12 days ago. Has this issue been looked into?
Are scripted operators still not supported with WorkSpaceTool?

I reported bug :
https://developer.blender.org/T63221
which was marked as duplicate of:
https://developer.blender.org/T60766

So it seems there is problem with proper regiestering of ‘modal keymaps’ (not sure what that is).

@JoseConseco thank you, I’ll subscribe to that.

This bug does not appear to be fixed in the 2.8 release candidate.
Am I expected to be fixed by release?
If so, what should we do?

I know the reply is a bit late. I got it working with this code registering empty keymap to defautl setting and then adding value to it:

kmToolQuickSlice = "3D View Tool: Edit Mesh, Slice"


keymapSnap = (kmToolQuickSlice,
        {"space_type": 'VIEW_3D', "region_type": 'WINDOW'},
        {"items": [
            ("wm.modal_quick_slice", {"type": 'LEFTMOUSE', "value": 'PRESS'},
             {"properties": []}),
        ]},)


emptykeymapSnap= (kmToolQuickSlice,
        {"space_type": 'VIEW_3D', "region_type": 'WINDOW'},
        {"items": []},)


        
def registerKeymaps():
    keyconfigs = bpy.context.window_manager.keyconfigs
    kc_defaultconf = keyconfigs.default
    kc_addonconf = keyconfigs.addon
    from bl_keymap_utils.io import keyconfig_init_from_data
    keyconfig_init_from_data(kc_defaultconf, [emptykeymapSnap])
    keyconfig_init_from_data(kc_addonconf, [keymapSnap])

def unregisterKeymaps():
    keyconfigs = bpy.context.window_manager.keyconfigs
    defaultmap = keyconfigs.get("blender").keymaps
    addonmap   = keyconfigs.get("blender addon").keymaps

    for km_name, km_args, km_content in [keymapSnap]:
        keymap = addonmap.find(km_name, **km_args)
        keymap_items = keymap.keymap_items
        for item in km_content['items']:
            item_id = keymap_items.find(item[0])
            if item_id != -1:
                keymap_items.remove(keymap_items[item_id])
        addonmap.remove(keymap)
        defaultmap.remove(defaultmap.find(km_name, **km_args))
