Hi
I created a compound widget and want to define a default “margin” of it.
Everytime I add my CW on a content it’s margin is set to “0px” by default but I would like to have a margin of “0px 2px”.
The width and height can be adjustet in the CW but if I try to add the property “margin” in the first line of the CW I always get an error “…margin attribute is not declared..”
Is it possible to define the default margin of a CW?
Hi Stefan,
I assume you’re using mappView 6.
In mappView 5.24, the property isn’t available, and I get this compiler error:
10 Error 03.02.2026 09:00:25,4889 The ‘margin’ attribute is not declared., XML syntax error. The object cannot be loaded. Ln:2, Col:60
Perhaps the margin value is overridden in the content. Can you open the content in a text editor and check this? But I think the margin property would then be highlighted in bold.
You’ve probably already tried a rebuild.
Maybe someone else has another idea 
Hi @Stefan_Ruttimann , what is the final answer on your question, have you investigated it?
I have no solution yet for this issue…
Looks like that this question you have to ask using local B&R support channel.
