Branch boxes

[Florentine van Bouwdijk]

Hi,

I want to branch boxes based on the attributes from the entities within the box. Is this possible? Because I couldn't find a way to do this, as the entity attributes are not showed in the output viewer of the box.

Thanks in advance!

Best regards,

Florentine

with the output viewer of the box I mean the container output

Florentine,

Use the 'EntityList' output for the EntityContainer to access the entities inside the container. For example, if the entities have an attribute 'attribA', then the following expression would return this attribute's value for the first entity in the EntityContainer:

'[EntityContainer1].EntityList(1).attribA'

You may need to ensure that the container has at least one entity. For example, the following expression returns -1 if the container is empty:

'list = [EntityContainer1].EntityList; size(list) == 0 ? -1 : list(1).attribA'

Note that a local variable 'list' is used to simplify the expression.

Hi Harry,

Thank you for your answer. But now I have the following input error: 

I gave every entity an attribute which is called "Country". What is the problem here?

Florentine,

[Worker].EntityList returns the list of entities in the container. The first entity in the container is [Worker].EntityList(1). Your expression should be:

'[Worker].EntityList(1).Country == "Italy"?1:2'
