Udo Schnurpfeil commented on TOBAGO-410:
----------------------------------------
in the Java Code you can use:
StyleClasses classes = StyleClasses.ensureStyleClasses(component);
classes.add???Class(...);
to modify the Style Classes. Here is also the possibility to use markups with
"addMarkupClass"
> attribute-tag causes ClassCastException

> Key: TOBAGO-410
> URL: https://issues.apache.org/jira/browse/TOBAGO-410
> Project: MyFaces Tobago
> Issue Type: Bug
> Components: Core
> Reporter: Matthias Wronka
> Fix For: 1.0.11, 1.0.12
>
>
> 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");
> In the current snapshots this causes a ClassCastException:
> java.lang.ClassCastException

> 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.
