Hi All

I want to check that a rich text is not blank, I added a ValidateExpression for a rich text to check its content but it doesn't work. How can I validate it?

Thanks in advance

<xp:inputRichText
               value="#{document1.Attachments}" id="attachments1"   style="width:99.0%">

                     <xp:this.validators>
                      <xp:validateExpression
                                  message="Attachment is missing">
                       <xp:this.expression><![CDATA[#{javascript: if (getComponent("attachments1").getSubmittedValue()!== ''){
 
                                     return true
                                      }}]]></xp:this.expression>
 </xp:validateExpression>
 </xp:this.validators></xp:inputRichText>
