Chart rendering failed... OnRender method. D2D error

[QuantKey_Bruce]

Has anyone had any update on this? It's actually causing charting to crash using only inbuilt indicators so I would think this would be a high priority to fix.

This isn't a bug in the Trendlines indicator - it's a bug that is exposed when there is more than one data series on a chart but some drawing objects are set to attach to all charts. When it does something like a duplicate chart, it tries to use the same name for the drawing tool when it adds it to both subgraphs, causing a crash that is not handled gracefully - the chart no longer scrolls or receives any new data after this. The issue reported above is related. They both are ways to expose the underlying bug, which is related to drawing objects on "all charts" when a chart has more than one subgraph of the same symbol as the drawing objects are attached to.

Hello Bruce,

This was reported to the correct channels but has not had an update from the development team.

I've pinged the team lead to see if I can get some action on this issue. Will keep you updated.

NinjaTrader_ChelseaB I'm also getting this and it halts the data ?
What is the ETA for a fix? (the error was reproted at 2007...).
How can I prevent this - any workaound?

I occasionally get this error when I open second workspace. Restarting NT always helps.

I suppose you can read this thread and draw your own conclusions about the situation. I was hopeful that after turning in a reproducible scenario, it would be fixed right away, but instead we now have what we now have.

Are we doomed ?
I would like to have global drawings and multiple chart and subgraph.. assuming that we will not get a fix soon, any guidelines or workarounds this issue?

[QuantKey_Bruce]

No, you're not doomed, but fixing bugs of this sort is clear not a priority, unfortunately, so you have to steer clear of the circumstances that cause the bug to be manifested until that changes.

Thanks, On my station the issue comes and goes, while on a friend station it is on daily basis.
what should he remove / change for avoiding this?
(I’ve read the thread and not 100% understand the root cause)

Hello Community,

So far the report has been assigned to a developer, but there has not been any update so far.

Internally this is being tracked with ID # NT-5772.

Unfortunately, we cannot provide an ETA with any bug report or feature request.

TheTradingMantis. Thanks for this information. I have wasted countless hours debugging my own code thinking that it was the source of the problem. Thank you for this.
Some comments in the post below indicate this bug was introduced in v26

https://forum.ninjatrader.com/forum/ninjatrader-8/platform-technical-support-aa/1202658-drawing-objects-freezing-my-chart

By incrementally installing different versions and utilizing the "Mantis ChartFreeze" indicator it can be positively verified this bug was introduced in v8.0.26.

Pls forward this to the dev as it may speed up the analysis work.

I have had to stop using global lines as well - a real pita.

NinjaTrader_ChelseaB NinjaTrader_ChelseaB I think i have undertood what the Dev are missing and I have a workaround you can use and help all.
ping me if you are intersted.

Hello eladlevi,

If you would like to provide your findings here, I will be happy to add this as a note to the report.

Hello eladlevi,

If you would like to provide your findings here, I will be happy to add this as a note to the report.

For some reason you allow multiple drawing with the same tag (you can see and even do it manually).
With this as given, the RemoveDrawObject(tag) gets a tag which is NOT unique and with the combination of other panel and global items there is an error.
To overcome this cases In all indicator that I use I've change the function to be as follows :
private void _RemoveDrawObject(string _tag)
{
if (DrawObjects[_tag] != null)
{
DrawObjects[_tag].IsVisible = false;
}
}

That solves the issue for now. But this is only workaround.
NT must solve the core issue.
