license_release doesn't always release the print composer license

[RickSchoen]

In our Arbortext installation, we have a customized print command that preprocesses our XML files before generating a PDF. Once the PDF has been generated, the customized command issues the license_release( "PrintPublishing" ) command before it finishes.

Most of the time this works just fine, but occassionally (a few times each month), the print composer license will not be released. Since we only have one license, I will usually hear from our users that they haven't been able to get a license for and hour or two. When I check the license server log, I can see which user last checked out the license. If I ask them the manually release the license (I wrote a menu item just for this), the license is released when they do so.

Is there anything more I can do to ensure that the license is released when the release_license command is issued?

Thanks,

Rick

Hi RickSchoen,

Would you be able to share the script portion where you can release the license after publish. I am stuck now on being able to bring up the publish box.

This is the function I wrote to release the print composer license:

function ucp_release_print_composer_license() {

if ( license_release( "All" ) != 1 ) {

response( "Arbortext Editor did not release the Print License!\n\nPlease select 'UCP > Release Print License' again!\n\n", "OK!" )\

}
else {

response( "Arbortext Editor successfully released the Print License.\n\n", "OK!" )

}

}

It may be a race condition, where the composer engine isn't done with the license when the request to release it happens. You could try putting it into a timer callback that keeps trying until it's successful, something like this:

function release_license_callback(data) {
  # the callback wants data param, but we don't need it so ignore it
  if (license_release("All") != 1) {
    # didn't work, keep trying
    return 1;
  }
  else {
    # success, cancel the timer
    window_set(current_window(), message, "Print license released");
    return 0;
  }
}

function ucp_release_print_composer_license() {
  # try every 5 sec until we succeed
  timer_add_callback(500, "release_license_callback");
}
