Stupid <br> question

[kirkor.grzegorz.bernas.com.pl]

Hi, sorry for stupid question but I can't find any information about:
I have <h:inputTextarea /> and I want to disable HTML tags but when I display content of this I want to convert new line characters to <br />

How to do it?

Hi

You could create a Facelets function or a Seam component to do this (since the enhanced EL allows for parameter passing).

@Name("myHelper")
@Scope(APPLICATION)
public class MyHelper ...{


  public String nlToBr(final String str){
     String retVal = null;
     retVal = //replacing the new lines
     return retVal;
  }
}

Then in the xhtml you can do this:

<h:outputText value="#{myHelper.nlToBr(myBacking.theText)}"/>

Or create a facelets function and have this:

<h:outputText value="#{foo:nlToBr(myBacking.theText)}"/>

If all you want to do is preserve line breaks when displaying user-entered text,
you could just set white-space: pre in CSS for your text areas. Like so:

<h:inputTextarea rows="3" cols="40" readonly="true" 
   value="#{mybean.remark}"  style="white-space: pre" />
