v2012.05.120327.32Bit.VCL - Problem TChartSubTool/TSubCharts

[JwSwing]

Hello,
i have a problem in last release of TChart. I'm using Delphi XE2, but i have also the problem in Delphi 2010. If i define two sub-charts in one chart with help of TChartSubTool, always the ide forget the settings of name-properties of TSubcharts.
This cause a exception, if i not rename the names after each restart of delphi xe IDE.

In Object-Inspector the "Name" of Subcharts are not set. In TeeEditor it seems to generate default names. This generation doesn't work in Delphi-System-Classes (try to use _1, _2 names) correctly.

Have anyone an idea or bugfix?

Hi,

I'm not able to reproduce it with Rad 2010 and TeeChart v2012.05.
Find attached the project I'm using. It only has a chart with a subcharttool and two subcharts, and I can load the project without any error in RAD 2010 here.

Hi Willi,

I can open and run the project I attached both with D2010 and RadXE2 and TeeChart Pro v2012.05. Does it reproduce the problem for you, or you are following different steps for it?

Hello Yeray,
your sample reproduces the error. Both Names of the TSubCharts are empty but i can compile and run your demo without futher error. That is very strange to me. My project has two empy TSubChart names and there is a EComponentError if I start my program with the error “A component named _1 already exists.”

I have attaches a picture to show you the empty name in your demo.

Your sincerely

Hi,

I have attaches a picture to show you the empty name in your demo.

Right. We can reproduce this here.

But that's strange. We've tried to open, build and run the project I attached some posts above in two different machines, Win7 32bit and Win7 64bit, and we found no error on loading, building nor running the application.
Both machines running XE2 with Update 4 and TeeChart v2012.05.

Hello Yeray,
on thing i have to mention: I can allays set the names of the TSubCharts manually, then the program does work. But the names are not saved in the dfm. I have so set allays the names if i load the unit.

Your sincerely

Hi Willi,

Ok, I'm happy to hear you found a way to make it work. But I'm still puzzled why the same project with empty names loads without errors in some machines and not in others.

Hello Yeray
have you any new info about this error? The workaround tends to be very annoying.

Your sincerely

Hello Willi,

I can't still reproduce any error here. Now I've tried it with v2012.06 and RAD 2010 and also with RAD XE2.

However, as said before, I've observed how any name you set to the Charts in a TSubChartTool's is lost when you Save&Load the project. But I'm afraid there's no progress yet on the ticket (TV52016287).
