To get notified about the reason why a GameplayAbility failed to activate, it is possible to assign a function to the delegate UAbilitySystemComponent::AbilityFailedCallbacks(). It contains a tag parameter. This parameter can be used to determine the reason why UAbilitySystemComponent::TryActivateAbility() failed, be it either:
the ability is on cooldown
the cost couldn’t be afforded
blocked by other abilities
the AbilitySystemComponent is missing required GameplayTags
However, when testing, the tag in the delegate is empty (or the delegate isn't even fired).
Where does this tag come from?
How to set that tag?
(1) Those tags are part of UAbilitySystemGlobals. It has tags for:
actor is being dead ActivateFailIsDeadTag
on cooldown ActivateFailCooldownTag
insufficient costs ActivateFailCostTag
blocked by other abilities ActivateFailTagsBlockedTag
missing required tags ActivateFailTagsMissingTag
invalid networking settings ActivateFailNetworkingTag
(2) They can be set by (example for cost)
Set the tags in DefaultGame.ini, using the corresponding FName (example for costs):
[/Script/GameplayAbilities.AbilitySystemGlobals]
ActivateFailCostName=My.Test.Tag
Make sure, the GameplayTag exists, e.g. in DefaultGameplayTags.ini
+GameplayTagList=(Tag="My.Test.Tag",DevComment="")
Initialize those tags by calling UAbilitySystemGlobals::Get().InitGlobalData(), e.g. in the constructor of your UGameInstance subclass.
How does that work
Example for costs:
in UGameplayAbility::CanActivateAbility() -> UGameplayAbility::CheckCost():
UAbilitySystemGlobals::ActivateFailCostTag is applied to optional out param OptionalRelevantTags if costs can’t be afforded
this tag is used in UAbilitySystemComponent::NotifyAbilityFailed() which
fires the delegate UAbilitySystemComponent::AbilityFailedCallbacks
This is similar for the other cases mentioned above (cooldown, block, …).

If I am looking at an issue in the Coverity user interface, how do I get the event tag or tags? I need to know a tag in order to suppress the finding using code annotations, as described in the question "How can I disable coverity checking using code annotation?" but I'm not seeing it or maybe don't know where to look.
The event tag is the first identifier-like word in each line of commentary that makes up the issue report.
For example, on Github, RcppCore/Rcpp issue 760 contains a screenshot that I have reproduced at half-size resolution with some annotations:
Zooming in on the code panel:
There are three events here:
alloc_fn: Storage is returned from allocation function operator new.
noescape: Resource new Rcpp::Rostream<true>::Buffer is not freed or pointed-to in basic_ostream. ...
leaked_storage: Failing to save or free storage allocated by new Rcpp::Rostream<true>::Buffer leaks it.
The event tags are "alloc_fn", "noescape", and "leaked_storage".
In this instance, all of them are associated with the same line of code (line 49), but in general they may appear on different lines and spread across multiple files.
To navigate to all of the events, use the Occurrences panel:
The Occurrences panel shows all of the events, organized into a tree, where child nodes are events in callee functions. The entire list is generally ordered in program execution order, although some events may be chronologically disconnected, for example if the finding involves multiple execution paths.
Each entry in the Occurrences panel has an event number (again, nominally chronological), the event tag, and the file name and line number. Clicking on an entry navigates to that event in the code panel.
Here are a couple related Synopsys support articles:
how to add code annotation? I do not know which name should exist with //coverity[]
Is there a document that lists all defect 'events' with their name and descriptions?
So I want to Trigger my Tags when the user accept cookies, obviously.
I tried different approaches, JSVariable, Custom JS, First party cookie and datalayer variable.
Now I have them all set in Triggers, for example if the JSVariable is true or if the first party cookie contains the cookie value I set, or the datalayer variable contains filled.
Now in Debug mode these Triggers actually seem to work. They all get Ticks under firing triggers, but the Tags don't seem to Trigger because I get another Trigger for some reason which states
gtm.load equals [variableName] (for example: gtm.load equals myJSVariable) and it always has this red X.
I just don't seem to find an answer to this problem.
Thank you all very much
So if anyone experienceses something similar (in case I am not the only dummy):
When you type in the eventname, it is about WHEN to look for your variable basically.
So for example you would enter gtm.load, when the site has been completely loaded. Then GTM would look for your CustomVariable
If I try to log benchmark->elapsed_time() in post_system hook, it just logs {elapsed_time} as if I called it from a controller.
CodeIgniter documentation says:
"post_system Called after the final rendered page is sent to the browser, at the end of system execution after the finalized data is sent to the browser."
It also says you are supposed to echo the elapsed_time() in a view to show it to the user, but... how is it possible that elapsed_time() is still being calculated after sending the finalized data to the browser?
I feel being lied to.
People keep saying I should use my own marks and get the difference, but that's not the same as using this...
Turns out the documentation also says:
"If the first parameter is empty this function instead returns the {elapsed_time} pseudo-variable. This permits the full system execution time to be shown in a template. The output class will swap the real value for this variable."
I went to the Output class and found the 2 marks it is using: total_execution_time_start and total_execution_time_end and I can use those in the post_system hook.
I have mount Page in this form (with one predefined parameter):
mountPage("/lista/${variant}", StronaEntityV2.class);
when parameter "variant" is given all is OK. But when parameter is absent (is OK too from application point of view) URL is build in form
wicket/bookmarkable/all....package...StronaEntityV2?8
It is ok too, but I will know that situation. In simple situation (with one predefined parameter) checking parameter is good, but in more complicated isn't so simple (and must maintain code in distinct places).
My ideal imaged solution is event
page.OnPageIsMountedOn(URL to_me)
I will accept wide range of solutions.
FORMAL: please integrate synonyms on tags wicket-1.6 & wicket-6, and create new wicket-7
Your page is configured to listen to /lista/${variant}.
When you do: setResponsePage(StronaEntityV2.class, paramsWithVariant) then Wicket will use the mount point and produce: /lista/variantValue.
But if you do: setResponsePage(StronaEntityV2.class), i.e. no PageParameters provided, then Wicket will ignore /lista/${variant} (because it doesn't match) and will produce a "default" page url, i.e. /wicket/bookmarkable/com.example.StronaEntityV2.
So the application controls which url should be used.
You can use optional parameter placeholder: /lista/#{variant}. Note that I use # instead of $ now. This way Wicket will produce /lista/ when there is no variant parameter provided. In the page constructor you will know that the url is always "/lista" but the parameter may be null, so better use: pageParameters.get("variant").toXyz(defaultValue) or .toOptionalXyz().
I've created a custom workflow in Plone, using Products.DCWorkflow. I've set the transition descriptions to a more verbose description of what just occurred and am trying to display them in a status message. I thought I would be able to do this using workflow variables, but I'm hitting what appears to be a permissions issue and don't understand why.
I've based my workflow on simple_publication_workflow, which provides a set of variables. I tried copying the approach used for the action variable, which has a default expression of transition/getId|nothing. I created an action_description variable, and added transition/description|nothing. With this, I get a None value returned. Without the |nothing option, the page redirects to https, indicating the user doesn't have the permissions required for a current action.
I've put a breakpoint into createExprContext in Products/DCWorkflow/Expression.py, and as the same user I can see the information I want in sci.transition.description. So I tried replacing the previous default expression with python:transition.description, but I get the same apparent permission problem.
I'm wondering why this is happening? Why is transition/getId a valid expression for a workflow variable, while transition/description is not?
