Breadcrumb links [message #3056]

Not sure if I have discovered a bug, or am just mis-using the framework:

I have a list2 screen which then allows navigation to a further list2 screen (so grandparent, parent, child) but don't really want to use a list3 pattern.

However, when I click on the breadcrumb to go back to the parent list2 screen, the grandparent list3 screen is diplayed with an error that nothing has been selected.

Is it necessary to use a list3 pattern?

Edit: This can be demonstrated in the DICT subsystem when going from tables to columns. If you then click on the tables breadcrumb you are returned to the database list with the error message 'Please select an item first'.

This is actually a bug Embarassed

The fix is as follows - in file 'include.session.inc' is a function called 'scriptNext()', and at line 2153 (or thereabouts) you shoud see the following code:

Code: [Select all] [Show/ hide]

if (!empty($current_task)) {
   $script_vars['current_task'] = $current_task;
} // if

Change this to the following:

Code: [Select all] [Show/ hide]

$script_vars['current_task'] = $GLOBALS['task_id'];

Try this and check that it works OK.
