Edit: The reason seems to be a external_link_interception javascipt somewhere deep in SBM which occurs when clicking external links......

function(e) {
  e.preventDefault();
  e.stopPropagation();
  openExternalLinkInNewTab(element.href);
  return false;
}

How can i deactivate it in this case?

Check out this topic. It is most likely the current configuration of the HTML Sanitizer affecting your goal. docs.microfocus.com/.../ttwa_system_settings

I think the issue may be that the HTMLJS widget becomes an embedded iframe.  Try one of the following options:

1. Add a URL control to your form.
2. Add a text field with a prefix and suffix to create the link.  Default the field to be your link text and use target="_top".  Like this.

Hi David, thanks for your reply.

I tried to create a text field like this:

Unfortunately my field appears after deploying like this:

So, it doesn't work.....Are there any other solutions? What do you mean by "Add a URL-Control to your form? I only see in composer these options:

Tried hyperlink, but there is only the option, to open in a new window....

Are there any other ideas instead of changing HTML Sanitizer-options in workcenter settings for all apps?

Thanks for any help.

For the first option of prefix / suffix, you will want that field to be fixed length instead of richtext memo.

And by URL control, I should have said hyperlink control.
