Flex adding subelements as properties to a custom component

Posted Wed, 2010-04-21 09:39 by rbezemer

I was trying to extend a TextArea control, and all was working well untill I tried to use my class like the following:

  1.  <widget:myhtmltextarea> <mx:htmltext> <!--[CDATA[
  2.             <DIV STYLE="text-align:LEFT;"><SPAN STYLE="color:#7DB73F;font-size:20px;font-family:'Times New Roman';">Title Text</SPAN></DIV>
  3.         ]]--></mx:htmltext> </widget:myhtmltextarea>

 

which of course resulted in the nice cryptic error message :

 Could not resolve <mx:htmltext> to a component implementation.

 

after searching I found this post which explained it all.

 

turns out you must declare the property as part of the same namespace so the correct syntax would have been :

  1.  <widget:myhtmltextarea> <widget:htmltext> <!--[CDATA[
  2.               <DIV STYLE="text-align:LEFT;"><SPAN STYLE="color:#7DB73F;font-size:20px;font-family:'Times New Roman';">Title Text</SPAN></DIV>
  3.               ]]--></widget:htmltext> </widget:myhtmltextarea>
