Hi,
from years i use dollar index indicator w/o any problems until now.
After last platform update to version 2.45.45 and API ver. 2.12.39. If i try to add DXY indicator on active chart - i receive an exception "Listener for in-progress candle is null"!
After this exception the chart stop feed prices. No problem with Quotes on left side in platform. i.e. in market depth table, in instruments table, in order entry pane - the quotes is moving.

Here is a java console output:

2016-05-17 15:18:07.022 INFO b - Checking cache change...

I have also another indicator which is derived from DXYindicator , they also give same exception.
I did the same test on another machine. The result was the same.

I encounter the same "Failed to add indicator to data manager..." problem while using a customized indicator.
@support: did you change anything in the custom indicator calls?

It still works well in older JForex versions, such as on Live, which is 2.45.41 currently.

My urgent call again (for almost 3 years now) to Dukascopy
1) Please keep Live and Demo the same version
2) Deploy beta versions to beta testers first before you roll out new releases.
You always change the demo version and use your customers as beta testers. This is not a good plan.....

Here is a simple example of this error

I took the CustomCandleIndicator.java file from the current JForex-API-2.12.33-sources.jar package, renamed the class and the indicator name only. Then I simply compiled it in JForex.
If I run it on JForex demo current v.2.45.45 ---> no indicator gets painted, but error "12:03:57 Listener for in-progress candle is null" appears.
If I run it on JForex live current v.2.45.41 ----> the indicator gets painted, but the chart and all prices freeze.

But if I run it on JForex demo on an old running version 2.45.43 (I did not update this version for some time) ---> the indicator gets painted, no freeze at all.

Please help!
How can I reload version 2.45.43 from your server? 2.45.41 and 2.45.45 seems not working!

We were unable to reproduce this with current JClient version.
