I wanted to use the style "cctlbreadcrumb01" from the CC default style.
I set cctlbreadcrumb01 in the stylevariant attribute, but the tabbedlinecontainer didn't take the style. I also noticed that the style was not available in the choice list for stylevariants (Style & macro).
Now I have seen in the default style.xml (version 4_0_20130507) that cctlbreadcrumb01 tags have names tabbedline and tabbedlinetab, but cctl01 til cctl04 have names tabbedlinecontainer and tabbedline. Then I have renamed both cctlbreadcrumb01 tags following the cctl0(i) pattern. Now it works.
Is this the right solution? Should you correct the style.xml in the CaptainCasa installation?
The only missing 1% is: please leave cc*-names to CaptainCasa. Otherwise we might come up with the same style variant but some difference in future time. So please rename it to "xpertbredcumb" or whatever...
And: I am sure you did not directly rename, but you copy pasted and then renamed.
We did not take over the breadcrumb variant for tabbedlinecontainer, because it usually is not used within a context of a container below... (The other cctl* ones are available.)
