[TYPO3] Keeping classes in htmlArea RTE

[Rodrigo Cea]

Hello,

While upgrading from 3.7 to 4.0.2, my RTE has started giving me problems.
Situation: I have a series of CSS classes defined in the RTE parapgraph 
settings. They show up in the selector, and I can apply and preview them 
in the backend. However, when I save them, the RTE cleans them out, 
replacing, for example: "<div class=titulo>" with "<p>".
Here's my page TSConfig:

# General configuration of the available classes:
RTE.default.disabled = 0
RTE.default.showButtons = 
cut,copy,paste,formatblock,bold,italic,underline,left,center,right,orderedlist,unorderedlist,outdent, 
indent,link,table,image,line,chMode

RTE.classes {
   titulo {
    name = Título
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:36px
   }
     subtitulo {
    name = Subtítulo
    value = font:bold; color:#666; font-family:"Century Gothic"; 
font-size:16px;
   }
   t2 {
    name = Título 2
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:32px
   }
   t3 {
    name = Título 3
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:28px
   }
   t4 {
    name = Título 4
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:24px
   }
   t5 {
    name = Título 5
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:20px
   }
   t6 {
    name = Título 6
    value = font:bold; color:#f90; font-family:"Century Gothic"; 
font-size:18px
   }

     firma {
    name = Firma
    value = align: right; font:bold; padding: 0px 0px 0px 24px;
      }
     cita {
    name = Cita
    value = padding: 0px 24px;
   }
}
RTE.default.classesParagraph = P, titulo, subtitulo,  t3,  t5, firma, cita
RTE.default.hidePStyleItems = H1,H2,H3,H4,H5,H6,pre
RTE.default.proc.allowTags = titulo, subtitulo, firma, cita
RTE.default.proc.HTMLparser_rte.tags.titulo.protect = 1
RTE.default.proc.allowTags = div
RTE.default {
	proc 	{
		dontConvBRtoParagraph = 1
		}	
	}
