[jira] Commented: (TOBAGO-410) attribute-tag causes ClassCastException

Arvid Hülsebus commented on TOBAGO-410:
---------------------------------------

Style classes are now handled by specific objects not plain strings anymore. In the Java code snippet this could be easily changed. 

But changing the style this way was not really intended anyway. With 1.0.11 we introduced the ability to provide markup for tc:panel and you can define the available markup values directly in the tobago-config.xml without the need to write a complete theme. See the address book demo for an example where we defined 3 different levels for a progress bar.

Can you switch to markup for your application?

> We use the tc:attribute-Tag to assign styles to components such as
> <tc:panel>
> 	<tc:attribute name="styleClass" value="tobago-panel-default my-style" />
> ...
> or using Java Code:
>        ivPanel = (UIPanel) ComponentUtil.createComponent(facesContext, UIPanel.COMPONENT_TYPE, "Panel");
>        Map lvAttr = ivPanel.getAttributes();
>        lvAttr.put("styleClass", "tobago-panel-default my-style");

> As this feature worked fine with version 1.0.10 we would appreciate a transition period, in which the styles are still assigned but a warning is logged. Currently our applications cannot use these snapshots.
