[opencms-dev] Duplicate NavPos

[Mathias Lin | SYSVISION]

Hi Mario,

it might be that the issue occurs only with imported files. If I create a
new folder and create files step by step using the 'new' button in the
toolbar like you did, I've haven't experienced the problem as far as I
remember - but not sure.

In our case, we've imported a website that was on v6.2.3 into v7.5.1. This
website hasn't made use of the NavPos property before, therefore no files
ever had a NavPos value assigned.
During the relaunch phase, I then moved the files to another folder and
assigned the NavPos values.


Beside that - I also found another issue just now: 
I use the allInFolderNavPos content collector, and find the following issue:

When all files in a folder (targeted by the contentloader) have a NavPos
value assigned, the sorting order works fine.
But if there's just one single file of this specific type in the folder, the
sorting gets messed up: 
- all files are sorted absolutely randomly, even the files with a NavPos
value don't show in order anymore
- even files without a NavPos assigned get displayed

This problem also occurs on the site where I have above mentioned problem
with the NavPos.

Here's the code I use for retrieving the list of files; (for debugging
purposes I also display the NavPos value for each file):

  <cms:contentload collector="allInFolderNavPos"
param="${autoLink}${type}_%(number).html|${type}" editable="false" >
        <c:set var="filepath"><cms:contentshow element="%(opencms.filename)"
/></c:set>
        <li><cms:property name="NavText" file="${filepath}" />
        <br/>Fore debugging: <cms:property name="NavPos" file="${filepath}"
/>,${filepath}<br/>
        <cms:contentshow element="Description" />
  </cms:contentload>


BUT:
If all files have a NavPos property set and the file list display well, and
- just for testing purposes - I then remove the NavPos property from one
file in the folder, the problem does NOT occur as expected. It only seems to
be with a folder/files where no NavPos has ever been set before (or maybe
only files that have been imported to the system).

Still trying to reproduce and will let you know if I have more concrete
details. Will add it to Bugzilla then.

Regards,
Mathias
