Tag already in use

[djkiwi]

Hi guys. I have an odd message appearing and would appreciate some help. When I put a line on my chart and put a tag in the data field it is ok for awhile.

The problem is if I delete the line and then try and add another line with the same tag name it comes up with the message (please see attached).

I notice it may occur when I use the attach to "All charts" but not sure. I am referencing this in a program as follows:

if ( draw.Tag.ToUpper().CompareTo("T1")== 0 ) {
targetone = (IHorizontalLine) draw;

The issue is the T1 tag cannot be reused. Any ideas on this one?

ps. I noticed if I opened a new chart and loaded the indicators on again the tags were ok, so for some reason the tags hang around on the old chart even though the indicators/lines are removed and then added in again.

Thanks
DJ

djwiki,

I am happy to assist you.

How are you removing this draw object? Could you possible post more of your code?

I look forward to helping you resolve your issue.

DJ,

Nice project you're working on here - I was able to reproduce, however only when I set the line as a global drawing object. Please note that there is no support for Global draw objects through NinjaScript at this time. You should not run into this when using a local drawing object on a single chart.
