I would link to create a link to a frontend page inside a backend module. Using:
<f:link.page pageUid="40" >Link</f:link.page>
Doesn't work. It generates a link to the current backend module.
Any solution ?
This is a very long story but the gist is: it is not possible to create FE links in BE/CLI context without a lot of workarounds and dummy objects/values.
If possible you should use solutions like pagepath which generate URLs for an eID script which performs the actual URL generation on demand.
