Problem solved by moving the code block inside of a function called in the method that loops through the collection. 

By the way, if there is a list of data type matches for decimal values (as I understood, float does not match all of them), I would really appreciate a link.

Кстати, если существует список соответствий типов данных для дробных значений (как я понял, float подходит не для всех), я был бы очень благодарен за ссылку.

Я нашёл необходимый тип данных, им оказался decimal. Вопрос можно закрыть

Вот ссылка на перечнь соответствующих типов:

Элемент процесса [Задание-сценарий] | Creatio Academy (terrasoft.ru)

I've found the necessary data type, it turned out to be decimal.

Above there is a link to a list of data type matches

Hi Anupama, 





 

One of the ways to create a loop in your process to work with the collection of records is  to create a sub-process and pass the collection into the subprocess. 

You can refer to the example below and create the process you need: 

Signal "Contact Added" element: 

Read Data "Read Contact" element:

For the sub-process, you would need to specify the [Parameters] of it:

And make a filter of the element within the sub-process based on the ID:

And finally, you would need to specify this parameter in the parent Business Process:

Hope this helps!

Thank you!

Thanks Yurii Sokil for the detailed instruction and the sequential  Execution Mode is something I haven't tried it before. Would definitely try that.

In between I tried another approach where-in at the entry point where the Signal action is placed, I unchecked the option of "Run following elements in the background". With this, until the process is completed, I was able to read the required values and add/edit/delete multiple records.

Hi Raz, 

In fact, an array will work almost the same as a collection, so it doesn't make any sense to pass array into collection, but in this case you need to read this json data and then pass it through the collection for your further actions.

Please check out some practical examples of how to read and update data in script task:

Kirill Krylov CPA,

Hi Kirill,

I don't understand you code.

So if shouldn't use this code in production.

what should I do?

I don't manage to get the values from ResultEntry.

Thanks,

Raz

Kirill Krylov CPA,

Your code is exactly what I need if I don't want to use "get a set of records" and if I don't what to use the "Formula" process element.

Why not to use it in production?

Hi!

Just add on saving event in your lookup entity, and add a script

Entity.SetColumnValue("Name", string.Format("[{0}][{1}]", Entity.GetTypedColumnValue<string>("Code"), Entity.GetTypedColumnValue<string>("Descritpion"));

Dmytro Oliinyk,

Thank you but that didn't seem to work for me, this was the solution for me:

var name = Entity.GetColumnValue("Name");
var description = Entity.GetColumnValue("Description");
 
var esq = new EntitySchemaQuery(Entity.Schema);
esq.AddColumn("Code.Name");
 
var CodeEntity= esq. GetEntity(UserConnection, Entity.PrimaryColumnValue);
if (CodeEntity != null) {
 
	var columnUsrCodeName = CodeEntity .GetTypedColumnValue<string>("Code_Name");
 
	string fullName= $"{name}: {columnUsrCodeName } - {description}";
	Entity.SetColumnValue("Name", fullName);
}
return true;

Let me know if there's an easier way to do this.

Kind regards,

Yosef

Hi Raz, 

Could you please provide a full script-task code you use so we will be able to test it at our end?

Anastasiia

The issue is that the process will execute asynchronously. The only way to get the value back from the process is, instead of using it as an output param, to send it as a message using a script task in the process that you will retrieve with client-side code on the page. 

You can see an article outlining how to do this here: https://customerfx.com/article/sending-a-message-from-server-side-c-to-…

Basically, at the end of your process, you'll add a script task. In that script task you'll get the param value, then send it as a message (as outlined in the article). Then, in your page code, you'll listen for that message, check to make sure it's the message sent from your process, and then read the value and do whatever is needed with it.

Ryan

You would use:

var myDate = Get<DateTime>("MyDateParam");

A date only param is still just a .NET DateTime struct just like a Date and Time value in Creatio -  A date only will just have a zero time value (so the value would be something like "Oct 29, 2020 00:00:00")

Ryan

Hi Ricardo,

Indeed, you can use the solution suggested above. However, please note that you'll get the date in a server timezone.

var myDate = Get<DateTime>("MyDateParam");

There is an option to pass a string as usual and parse it then. Also, you can pass ticks and use the result. For example: 

long ticks = Get<long>("MyDateParameterInTicks");

new DateTime(ticks, DateTimeKind.Utc).ToLocalTime();

Please read more about ticks property by the link below:

https://docs.microsoft.com/en-us/dotnet/api/system.datetime.ticks?view=…

Anastasiia Markina,

That is good to know, thanks Anastasiia.

IIRC the DataValueType param expected here isn't an enum. Try changing the code to add this:

var dataValueTypeManager = (DataValueTypeManager)userConnection.AppManagerProvider.GetManager("DataValueTypeManager");
var textDataValueType = (TextDataValueType)dataValueTypeManager.GetInstanceByName("Text");

Then use:

storedProcedure.WithOutputParameter("res_msg", textDataValueType);

Ryan

Ryan Farley,

Thanks. Now it runs.

But sorry, I still need some help on recovering the output prm from the stored procedure. It always returns "Core.DB.QueryParameter", instead of the string returned by the SP.

Ricardo Bigio,

You can capture that using this:

var resultParameter = (string)storedProcedure.Parameters.FindByName("res_msg").Value;

Ryan

Perfect. Thanks
