ConcurrentModificationException when use async

an_nguyen — Fri, 18 Jan 2019 03:23:02 -0500

Dear all, Our team is facing a very strange issue like this: We defined html dialog with 3 p:remotecommands with async flag is set to true. And occationally we got the ConcurrentModificationException when access to that page. Till now, we didn't find any effective way to reproduce it. It happens on Ivy Engine version 7.1

May you have a look and support us if you find out something from it. Thank you so much.

Here is the log. The function loadOpenAmountChart is one of 3 listeners of the remoteCommands

How to define 'from' inIvy.Mail with spaces and special characters?

an_nguyen — Tue, 25 Sep 2018 22:50:31 -0400

Dear all, Sorry for creating a new topic. My original question was this one https://answers.axonivy.com/questions/3431/how-to-define-sender-name-in-axon-ivy-mail

I wanted to define a sender name in Ivy.Mail. And Thank @Reto Weiss, your instruction helped. But the problem is that I can't send an email defined 'from' with spaces and special character. The text I tried was 'Sony AG, john.smith@sony.ch'. Many thanks,

How to define sender name in Axon.Ivy Mail?

an_nguyen — Thu, 20 Sep 2018 05:02:50 -0400

Dear all,

We are using Ivy.Mail to send emails and now we need to define sender name for those emails. Here is what I expect:

In the picture we have "Sony AG, ..." as a sender name beside "noreply@klara.ch".

But seems that Ivy7 doesn't support us to do it.

Actually, we can solve it by using Java Mail (we need to get email configuration from system properties). But it is not a official way and it is not very nice to get the email password from system properties.

Do you have any ideas regarding this situation? Many thanks
