[RESOLVED] Adding unique tag after adding component

[Radjesh Klauke]

Ola,

I'm adding labels at runtime to my form with a tag.

Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1.

When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist.
So my "solution" isn't a very good one

Although tag "2" is free, I want to give it "4".

Any thoughts on how to code this properly?

Use a variable to store the next tag and method to get the next tag. The method will get the current value of the variable and increment it. So you're always guaranteed to get increasing values.
