ListClear action in Service Studio?

ListClear action in Service Studio?

  
Dear All,

It's very easy to fill an array (Record List variable type) in Outsystems.

I'm currently trying to clear an array in a generic way.
I.e. by calling a (currently non-existing) ListClear action.

Offcourse It's possible to create another variable with the same but empty structure,
but it would be very nice to have this in a function.

Regards,

Eric 


Hi Eric,

You can use the attached extension to do what you want. You have to call the method in Service Studio passing the RecordList variable enclosed in a ToObject() call.

Hi André,

Thanks for your quick response.
I'm getting compile error:

NET Compilation.
 
GetFrameworkPaths:

Install the .NET Framework SDK.  2.) Manually set the above registry key to the correct location.

Hi Eric,

Forgot to include a dll in the extension.

See if this one's ok.

Hi André,

After I've changed the IPP on the XIF. (http://www.outsystems.com/ipp/)
I was able to publish the extension.

This works like a charm; thanks and thumbs up!

Any chance of a JAVA version being created for this or an adoption in the platform under Built-in Actions as ListClear ? :)

Hi Eric,

Glad I could help.

Attached is full version both for .NET and Java.

Thanks André!
Hi Guy's,

Is there any chance that the ListClear() function is adopted as part of the Built-in functions?

A ListInvert() and ListSort() would be nice too by the way. ;)
Hi Eric,

Well, I'm taking a chance here and say that there is indeed a good chance that the ListClear action will be part of Service Studio's built-in functions in the future.

I won't say the same for the ListInvert and ListSort, though, but you can always propose that in our Wisdom of the Crowds ;)

Thanks!

I will post the idea there!
Check also the ListUtils component.

Thanks Gustavo, that indeed provides a part of what I need.
