[BUG] 1.3.0 branch The task running order in the process instance does not follow the topological order in the process definition

[hlzhu1983]

1. process definition
   
2. task instance order in database
   
3. task instance order in web ui
   
   4.task instance order in process instance
   

The task running order in the process instance does not follow the topological order in the process definition, Why?

[xingchun-chen]

Please check the preTasks field value of the database table t_ds_process_definition.process_definition_json，If the preTasks are empty, it should be caused by not clearing the cache when creating the workflow definition. You can clear the browser cache and re-edit the workflow definition

[hlzhu1983]

that's right!
thanks!

Regarding the front-end cache, the front-end currently adds a version number when compiling, and it is still being tested. This problem will not occur in versions after 1.3.0.
