Update tag value

[Markus Rohner]

I want to update an existing tag value (eventDefinition) of an BPMN2.0::StartEvent.
First I tried it with adding an new tagged value to the event.
But I noticed, that the event already got that tag (eventDefinition = None) and I got two tagged values with the same name.
So I wrote code to loop through the tagged value and to set the desired value using SetAttribute (according to Enterprise Architect Object Model).

// Create a new element in the package
EA.Element scheduleEvent = collabModelElements.AddNew(JobStartEventName, "BPMN2.0::StartEvent");
scheduleEvent.Stereotype = "StartEvent";
                       
// Set Timer as TaggedValue
EA.Collection scheduleTags = scheduleEvent.TaggedValues;

// Search the tag collection
for (short i = 0; i < scheduleTags.Count; i++)
{
    EA.TaggedValue currentTag = scheduleTags.GetAt(i);

    // Update the tag
    if (currentTag.Name == "eventDefinition")
    {
        Console.WriteLine("&&&& FOUND Event Tag: " + currentTag.Name);
        currentTag.SetAttribute("eventDefinition", "Timer");
        currentTag.Update();
    }
}
scheduleTags.Refresh();

scheduleEvent.Update();
collabModel.Elements.Refresh();

The tagged value is found (I get that Console output), but the tagged value is still "None".
What am I doind wrong?`
Thanks.

Try enabling 'Show Duplicate Tags' in Tagged Values window to make sure there isn't a hidden tag that you are writing too.

'Show Duplicate Tags' is enabled. But there (Properties > Tags) are no tags visible.
I can see them all in the Element Browser.
And there I could see two tags with the same name, when I added the tag. One tag was still 'None' and the other had the value 'Timer'.

When I update the Event in EA (Properties > BPMN2.0 > Type --> Timer) the tagged value gets changed and the icon gets updated (circle with a clock).

I have used the below syntax for some of tag updates never had any issue

if tag.Name = "eventDefinition" then
tag.Value = "Link"
tag.Update
eaElem.TaggedValues.Refresh
End If

The problem is here:

Code: [Select]

currentTag.SetAttribute("eventDefinition", "Timer");
I'm not sure what the SetAttribute is used for structured tagged values (I've never used that). But I'm pretty sure you should just set the currentTag.Value, so

Code: [Select]

currentTag.Value = "Timer");
Also you don't need all those Refresh() calls. Why does everyone keep including those. You only need those if you add or remove an element from a collection. Refresh() will then make sure it contains the correct number of objects. I almost never use that.

Code: [Select]

currentTag.Value = "Timer");did the job.

Thank you Nabil and Geert

I'm using all these Refresh() because I'm quiet new to EA API progamming and learned from example code. Obviously I didn't know what this Refresh() is doing.
Thanks for this hint too.
