Style on Flash Builder 4

Question

Hi again
There is another problem
I want to set an style on a <s:span /> tag in <s:TextFlow /> in <s:RichText /> tag...
Style is something like this
     <fx:Style>
        @namespace s "library://ns.adobe.com/flex/spark";
        @namespace mx "library://ns.adobe.com/flex/halo";       
        .testStyle
            font-family:tahoma;
            font-size:80pt;
    </fx:Style>
If I set my style on my RichText with styleName attribute, it will be appear and all thing is right. But if I set it on span tag, with same att., it will not work!
code is like here:
     <s:RichText id="richtext1">
        <s:TextFlow>
            <s:div>
                <s:span styleName="testStyle">
                    Some Text...
                </s:span>
            </s:div>           
        </s:TextFlow>       
    </s:RichText>
what should I do?!

Answer 1

Anyone else have no idea?!
I think we can not do that, in this way.
After many web searches, I figured this out that we can use <s:format /> tag instead of styleName att. inside of <s:textFlow /> for samples like this.  I think Flex can't know entire tags such as <s:div /> or <s:span /> in <s:textFlow /> to set specific style that we defined in <fx:Style /> part with styleName...
Something like this, for the sample above:
     <s:RichText id="richtext1">
        <s:TextFlow>
            <format code="TStyle" fontfamily="tahoma" fontsize="80" />
            <s:div>
                <s:span format="TStyle">
                    Some Text...
                </s:span>
            </s:div>           
        </s:TextFlow>       
    </s:RichText>
Am I right?!
