[JBoss jBPM] - Re: [jBPM][3.1.1] Get a timer instance with API
by ephemeris-lappis
Ok for the fix you did on the JIRA...
Now, more details about my needs...
After a task terminates, the process decides to follow a transition to a new task. This last one must start initializing a timer that must fire after a given timeout. This timeout must be calculated according to business informations that are provided by the finishing step.
Ideally, a script expression directly given in the timer definition in the XML file could be perfect i the value formula is not too complicated. But i suppose that such a solution doesn't exist...
The alternative i had tried, was to intercept the task creation event, and change the timer delay. But if i understand what you say, it seems it's not a possible solution...
So what should i do ?...
Thanks anyway for your help, and any new idea is welcome...

We actually discussed this idea for managing the layout of pages. You should see something of this nature in 2.6, when we introduce the ability for users to customize pages. Ideally, the same functionality can be introduced to the admin side.
Google, actually had something like this (drag-n-drop wysiwyg layout builder) in their first versions of their portal. For some reason, I can't find it anymore, but it was a killer feature.

A good idea, but it gets tricky. Layouts (# and names of columns) are currently defined in jsps, so this would have to change in to making layouts dynamic.

True. The only workaround for now, is to have X# layouts deployed, allowing for the user/admin to pick whichever he wants.

Right. Thats the way it used to be. I'll see if I can get that behaviour back for 2.6, or even 2.4.

All items noted. The Admin Portlet will literally be gutted and completely redone for 2.6. Usability of that portlet is our main concern with it. If there is time, we also plan to introduce wizards.

[JBoss Seam] - Re: ConcurrentModificationException
by bfo81
You cannot change the length of a Collection (by adding or removing items) while iterating through it.
You can
- make a copy of the account collections, delete accounts from that copy during iteration, clear the account collection and insert all elements of the copy into the account collection *uff*
- insert all accounts to delete into a toDelete collection during iteration, and then iterate over the toDelete collection and delete items from the account collection.
Confused? Here's an example for the second way:
public void filter(...) {
| Collection<Accounts> toDelete = new ArrayList<Accounts>();
| for (Account a: accounts)
| if(accounts.notAccessibleBy(user)
| toDelete.add(a);
| else if (accounts.accessibleBy(user)
| continue;
| else
| toDelete.add(a);
|
| for (Account a: toDelete)
| accounts.remove(a);
| }
btw: The checks you make (notAccessiblyBy, accessibleBy) seem to be a bit weird ;). It looks like you want to keep ALL accounts in the collection or delete ALL of them. Wouldn't it work like this?
public void filter(...) {
| if (accounts.notAccessibleBy(user))
| accounts.clear();
| }
