I need to get this work — how can I code this to get the parse-order I need?
{exp:channel:entries channel='{exp:plugin entry_id="{segment_3}"}' …
As you can see in the code above: I read out the 3rd segment of the url, paste it in a attr of a plugin and use its output as a value of the channel-attr of exp:channel:entries.
Right now it does not work, the plugin with the segment-readout does work outside of the exp:channel:entries-Tag, therefore I think it is a parse order issue.
