Ok. Next random question from me! Is there a way to turn OFF the evaluation of strings as expressions in flogo-web (Ie a trigger field). OR is there an easy way to add scope to the parser in the web editor?

tibmatt

@tibmatt

More detail. It’s a custom trigger that has a custom expression language in the settings. But flogo-web is trying to evaluate it as an expression and when it sees errors won’t let it save

@mellistibco

Hmm good question. I don’t think there is an easy way disable validation. Other than of course just changing the code hehe. @fcastill

I suppose if it were just a string and you escaped any special chars it would work but that’s pretty ugly

Fabián Castillo

@fcastill

No, there’s no way to disable the parsing currently. I don’t think escaping the characters would do the trick either.

Right now the UI tries to infer when you’re defining a number vs string vs an expression (which is also a string but that it should be parsed) . I think we need some way to allow to define a string explicitly 🤔

tibmatt

@tibmatt

maybe in the descriptor add something like “parse”:true|false. If its not present it should be true

Hi team, does the Flogo engine have hooks for OpenTracing?

Alexandre Vazquez

@alexandrev

There is a listener from square-it

Leon Stigter

@retgits

so the engine itself doesn’t emit metrics? :cry:

Alexandre Vazquez

@alexandrev

Metrics? Yep.. you have a metrics API...

Leon Stigter

@retgits

oh nice! are there any docs or examples for it?

I didn’t seem to be able to find them on the docs site :(

Alexandre Vazquez

@alexandrev

Mmmm mmmm

Now thinking if this is only for Enteprise mmmm

Let me check :)

Leon Stigter

@retgits

Here I am all excited about using this and now you tell me this?! :joy:

Vijay Nalawade

@vijaynalawade

@retgits You can build your own metrics collector :-)

@retgits

Okay!! Totally need to check that out

Thanks for pointing me to that page @vijaynalawade

Inside a subflow, can you get a property in the parent flow's scope? In my activity, I use myValue, ok := ctx.ActivityHost().Scope().GetValue(myPropName) to get the value of a flow property (which is not explicitly mapped in the UI). It worked fine in the main flow, but it does not work in subflow because myProp is not in the subflow's scope.

@retgits

Hi friends :) is the new activity model completely final, and if so where can I find a good example? I really want to move my Flogo contributions to support the new activity model (and build a few new ones :wink: )

Matt Ellis

@mellistibco

👋 it is. Check out all the activities in GitHub.com/project-flogo

Leon Stigter

@retgits

any particular ones you think are exceptionally well? ;-)

Matt Ellis

@mellistibco

Aren’t they are all well written 😂 check out the rest activity

Leon Stigter

@retgits

I totally assumed you would say yours are really well :smirk:

Matt Ellis

@mellistibco

@ayh20

@retgits I updated some of mine to 0.9 ... for example.... Activity: https://github.com/ayh20/flogo-components/tree/master/activity/mqtt .... Trigger: https://github.com/ayh20/flogo-components/tree/master/trigger/udp

No guareentee that they are done well !

@yxuco

I am looking for an API to get the scope data of the parent flow inside a subflow activity, and found that it would work if the host in the project-flogo/flow/instance is exposed, e.g.,

func (ti *TaskInst) Host() *TaskInst {
    h := ti.flowInst.host
    ti.logger.Infof("got host: %+v", h)
    if inst, ok := h.(*TaskInst); ok {
        return inst
    }
    return nil
}

then, I would be able to access the scope of the parent flow by ti.Host().ActivityHost().Scope(). Does this make sense? Is there an API that can achieve this already?

Samip Kothari

@skothari-tibco

I don’t think if there’s an API to do that.

when using flogo create, what is the correct syntax to force it to use flogo core/flow 0.9.2? my models are broken when flogo core/flow 0.9.3 is used.

Matt Ellis

@mellistibco

What’s broken in 0.9.3?

-cv is the switch

https://tibcosoftware.github.io/flogo/flogo-cli/flogo-cli/#create

Yueming Xu

@yxuco

tried the following, and failed, guess it does not work with github tag version.

flogo create --cv 0.9.2 -f audit.json audit_cc
Creating Flogo App: audit_cc
Installing: github.com/project-flogo/core@0.9.2

@v0.9.2

Yueming Xu

Matt Ellis

@mellistibco

two @ :)

Yueming Xu

@yxuco

flogo --version
flogo cli version v0.9.0

maybe cli version?

Matt Ellis

@mellistibco

flogo create --cv v0.9.2 -f audit.json audit_cc

Yueming Xu

@yxuco

Thanks. that works, although it changes only core@v0.9.2, flogo/flow is still using v0.9.3. by the way, the problem was that the model uses $.value to map array items, which does not work with v0.9.3. hope that the version of flogo/flow does not matter.

Matt Ellis

@mellistibco

you can add the import into flogo.json: imports[ "github.com/project-flogo/flow@v0.9.1”]

and then flogo imports sync (i think its sync)

Yueming Xu

@yxuco

will try that if it is an issue. thanks.

Just working from the project-flogo getting started page:
wcn00@gandalf:~/go/src/github.com/wcn00$ go get -u github.com/project-flogo/...^C
wcn00@gandalf:~/go/src/github.com/wcn00$ flogo create -f flogo.json
Creating Flogo App: SampleApp
Installing: github.com/project-flogo/core@latest
Error creating project: open pkg/mod/github.com/project-flogo/core@v0.9.3/examples/engine/main.go: no such file or directory

Should I be using project-flogo or TIBCOSoftware/flogo?
