Constraint on custom xbl component

I have a custom control to which I want to add a required constraint. Custom control has two elements; a div and a button control. When button is clicked I create a span with some value and add it to the div. End result will look like a table with multiple rows. Field(list) which is bound to this component is a required field is required and I need to display the red required icon and when user adds at least one item I need to display the green check mark.

Approach that I took is, when button is clicked I trigger an event and add values to the list in the modal. Custom component has a repeat which displays the values from modal.

I can't seem to make the required icon to show up. I would appreciate if you can point me to an example or documentation.

Thanks

Binesh,

Since you need to have both a required icon and a green check mark
icon, I think I would just display then with two <xforms:group
ref=".[condition]">icon</xforms:group>, where condition is that the
number of fields is 0 for required icon, and that there is 1 or more
fields for the green checkmark icon. Does this make sense?

                </xbl:template>
        </xbl:binding>

This is working for me. I understand that I can use two groups with condition too but this might be a better way of doing it. what do you think?

Thank you
Binesh

MY BAD. I reported wrong solution. This is what worked for me.
