No, explorer does not use REST at all, it leverages the VAADIN comunication to call the Java-API directly on the server. DO you see any stack traces when you search for users, in the tomcat log?

You must type the first 2 letters of users' surname. Below is the code of org.activiti.explorer.ui.custom.SelectUsersPopupWindow

protected void searchPeople(String searchText) {
………..
      List<User> results = ProcessEngines.getDefaultProcessEngine()
              .getIdentityService()
              .createUserQuery()
              .userFullNameLike("%" + searchText + "%")
              .list();
…….}

I cant choose fozzie or gronzie even in new process start-up for the Sample Approval Process.
I am posting this messenger here because I dont see any where here how to post new thread.
Please let me know answer to both.
I renamed the rtf as .txt I could not upload anything other than .txt. See if you can rename it to .rtf and see my screen shot.
Otherwise email me and we can do screen share session and I can show the issue.
Thanks

Re: can't select user in reassign window

pbhat — Fri, 01 Nov 2013 20:12:30 GMT

Cant assign or reassign for any process in 5.14. Is something seriously broken as assigning tasks to other users is core functionality of BPM. I am trying to do a prototype to use Activiti in production; but if such as major functionality is broken it is hard to convince stake holders. Please suggest work around or provide fix soon. Others are reporting similar issue. Should we try a previous version? If so which one?
Thanks,
Prakash

Re: can't select user in reassign window

pbhat — Tue, 05 Nov 2013 16:50:08 GMT

As mentioned by others
You must type the first 2 letters of users' surname or last name. Or typing %% gets every one. Case sensitive.
my Issue resolved.
Thanks

Re: can't select user in reassign window

faisalgeek — Thu, 26 Dec 2013 06:42:41 GMT

Username search is case sensitive, so type Fo Or Go will show the respective user OR typing %% will show all users. I was having same problem before.
