It will be cool, if I can create meter chart with chartCreator.

Thanks for your source code.

Is there any demo war file?

[cagatay_civici]

There is no example war file.

The component joined jsf-comp project in sourceforge, now both the source and the component itself is available in sourceforge. I will no longer distribute it from my blog, The adress is;

http://sourceforge.net/projects/jsf-comp/

Hi Cagatay,

I already noticed this and put a new announcement at the top of the forum:

Thanks for all your work on this!

I followed your documentation on sourceforge and am having problems with version conflicts when trying to import a new uri to my project. RAD is telling me that the tld is version 1.2 and the project is version 1.1 and it stops me there. Anyone have ideas what the problem could be?

[cagatay_civici]

Never been told about an error like that, this is the first time. Maybe more info should help, what is the server environment you are using and what do you mean by project's version is 1.1? eclipse's .project file or what?

Strangely enough, the component's tld is version 1.0 actually, if you look at the tld you can see that. This may be a general problem with your configuration.

Regards,

Cagatay,

Hi all!

I am trying to use chartcreator - I did all the steps on the jsf-comp page - and all the classes are found, the method public DefaultPieDataset getPieDataSet() gets called but, when Chartless.java processes it I get the stack trace:

Code: Select all

ERROR: Servlet.service() for servlet Chartlet threw exception (2006-03-23 19:15:47,562 http-8080-Processor21_org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/sakai-sitestats-tool].[Chartlet])

Hi, I'll be releasing the version 1.2.0 RC1 this week, I could add this optional feature in the new version but first we've to find a way to make these boxes and links invisible. I've found a method to make the links invisible but no luck with the labels themselves. Any ideas?

Does this release candidate have the fix for using a variable in chart type?
If so, I'll take it the minute I can get my hands on it... We're releasing our software to beta in days and I could just squeeze this in to fix the problem.

[cagatay_civici]

Yes, the 1.2.0RC1 fixes this bug and a lot more. Also some new features are added. It'll be released tonight.

[jakorsme]

I sent you an email to your address. The RC is seriously broke. Endless redraw loop.
