I have recently downloaded and installed TeeChart 2013.08.130521. I am on Delphi XE3 Ultimate and now get an error stating

Error reading Chart.DefaultCanvas: Property DefaultCanvas does not exist

This occurs in any existing application using TeeChart components when I attempt a recompile.

Please can you assist.

Many thanks

Rob

Please note that Embarcaderos own documentation for XE3 only mention DefaultCanvas in relation to the FireMonkey canvas manager; NONE OF MY APPLICATIONS USE FIREMONKEY OR ARE DEPLOYED ANYWHERE OTHER THAN WINDOWS PCS

Hi,

DefaultCanvas is a new property in TeeChart v2013.08. The component adds this property to the dfm at design time. But your IDE is probably finding an old version of the package before the new one when compiling the application, a version that doesn't have this property defined.
Please, check the paths:
- Check the paths in your IDE, with no projects loaded. Remove any reference to old TeeChart installations.
- Create a new simple project with just a chart on the form. Does it work fine?
(No) - Check the paths again. Check also the packages list. Uninstall TeeChart and reinstall it if necessary.
(Yes) - Open and build your old application. If it doesn't work fine, close it. Open the project files with notepad or similar, and correct any reference to an old TeeChart installation you may find hardcoded.

Thanks once again.

Naively I assumed that the Steema Install program would remove the old references to Teechart, and replace with the new; when it just adds the new onto the end of the list. Something I shall look out for a the next upgrade.

Thanks once again.
