Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
We know that for a primary particle, it will produce one or more tracks. One is the primary track with a track ID, and other secondaries have their own tracks with track IDs, and we can also obtain their parent IDs.
Now, if I want to know the original primary track ID for a specified track, what should I do to obtain it?
In the example RE01, there is a method by invoking the userTrackInformation to get the primary track ID for each track. But I cannot make sense the statements there.
Does anyone have a easy way to obtain the primary track ID for a track?
Thanks a lot.
