Custom Rule Action does not deliver actionItems2 parameter in ExecuteAction2

0053X00000EBapeQAD · September 15, 2025, 2:08pm

According to the BatAction example we implemented a RuleAction.ActionManager which returns an ActionDefinition with two ActionElements, onbe of which is of Kind.Camera and a custom Kind. The custom kind we registered in the PluginDefitnition as a ItemNode of the same custom Kind which is used for the ActionElement.

This works as far as we can select the camera and the custom kind, which represents a time span in this case. The selections are persisted and the rule is executed according to the trigger definition.

But, when the actual call to RuleAction.ActionManager.ExecuteAction2 is made, the parameter for the second action item actionItems2 is empty.

In the log of the Event Server we see the following two entries which appear at the same time, rule is triggered:

2025-09-15 15:13:00.217+02:00 [ 184] ERROR - MipActionHandler Unknown event source. Source: a6eafb52-f591-451d-b02e-522d3f875811

2025-09-15 15:13:00.217+02:00 [ 184] ERROR - MipActionHandler Failed to lookup action target. Id = 3b4be07d-d538-4fec-b0ec-0d644cea6603

Maybe you can push us in the right direction here?

Thx

Daniel

First idea and question. Is the plugin loaded in both the Management Client and the Event Server?

0053X00000EBapeQAD · September 16, 2025, 12:13pm

Yes. I can see the Init() call in both logs, Event Server and Management Client. The Background Plugin is also loaded for the Event Server.

The Guid for the custom Kind is also the same for the ItemNodes and ActionDefinition.

The second Guid mentioned in the two log entries above (target.Id 3b4be07d-d538-4fec-b0ec-0d644cea6603), is one of our custom Kind “Time ranges”.

The first Guid called Event Source we can not find anywhere.

Could you please try run the BAT action sample and see if you see the same with that? From your description it seems like it is very much the same, but I just tried it and it seems to work fine.

Also, I tried to look up the a6eafb52-f591-451d-b02e-522d3f875811 and it seems to be related to rules that are triggered periodically/recurring. Does this match the rule you have? That said I tried to make one like that and still could not reproduce, so if you can provide details about the rule it would be greatly appreciated.

Hi Peter!

The BAT Action Example is running fine with an identical rule!

As you suggested, we defined a rule that is running periodically at a specific time once a day. So this explains the other Guid we see in the log.

Our plugin does not only have the Background Plugin running on the Event Server, but also creates ItemNodes that appear in the Management Client for configuration and in the Desk Client we have ViewItemPlugins and WorkspaceToolbarPlugins running.

I have the feeling we are missing something quite obvious, but can’t get my mind around it.

Why would the built-in event source be unknown to the Event Server?

Peter_Posselt_Vergmann · September 17, 2025, 10:29am

Since it is not happening for the BAT action sample I tend to think that the “Unknown event source” is a side effect of the other one, so let us focus on the other one for now.

The code reporting the “Failed to lookup action target” is trying to look up the FQID of the item you have selected, so my guess is that something is going wrong in the ItemManager delivered by your plug-in. Maybe you can put some logging in the GetItem methods and see whether they are called when the rule executes and if so whether they succeed in looking up the Item?

0053X00000EBapeQAD · September 17, 2025, 12:23pm

When the rule executes, the ItemManager’s GetItem methods are not called at all.

The GetItems() is called when configuring the rule. The GetItem(…) methods with parameters are never called.

Here is the GetItems() implementation:

public override List GetItems()

{

List items = new List();

EnvironmentManager.Instance.Log( false, “RadiometryGraphsExportItemManager::GetItems():”, $“” );

foreach( var intervalItem in _exportIntervals )

{

EnvironmentManager.Instance.Log( false, "RadiometryGraphsExportItemManager::GetItems", $"Item registered: Key:{intervalItem.Key} Value:{intervalItem.Value}" );

items.Add(

  new Item( new FQID( EnvironmentManager.Instance.MasterSite.ServerId,

  Guid.Empty,

  intervalItem.Key,

  [FolderType.No](https://FolderType.No),

  RadiometryGraphsDefinition.\_exportActionKind )

  { ObjectId = intervalItem.Key },

 intervalItem.Value ) );

}

return items;

}

_exportIntervals looks like this:

public static Dictionary<Guid, string> _exportIntervals = new Dictionary<Guid, string>() {

 { new Guid("9dcf878a-a2ae-4be7-86e5-c15a8015f4c0"), "24 h" },

 { new Guid("8174ab13-fca0-4481-9633-0b471c3d5fd6"), "12 h" },

 { new Guid("6688f6dd-1bc2-4edf-95a0-66dd9fc6b969"), "6 h" },

 { new Guid("3b4be07d-d538-4fec-b0ec-0d644cea6603"), "3 h" },

 { new Guid("a0e00f24-9cf6-4dd3-bf82-280f0604219b"), "1 h" },

 { new Guid("19fe530e-9a34-4222-b1c9-b03c5e8285cb"), "30 min" },

 { new Guid("4d53866d-8b94-4381-9f65-b574e7bd0795"), "10 min" },

 { new Guid("2f2a7500-49d5-4eca-a3f8-8b80e767113c"), "5 min" },

 { new Guid("c0c4f0db-b5d1-49ed-b686-33f3f99e024c"), "1 min" },

 };

and logged is this:
