I see that between the two tables you have various different versions of task_id, namely:
- task_id
- parent_task_id
- blocked_task_id
- waiting_task_id

How are you converting 'task_id' to any of the other values? When passing context between database objects there is no automatic conversion of column names, so you will have to do it manually.

If you look in the menu system at the relationships between the MNU_TASK and MNU_MENU tables you will see that the column name 'task_id' has to be translated to either 'menu_id' or 'task_id_jnr', and this is done by custom code as it cannot be done automatically by the framework.
