Well... you DID say "If I just bind the text to a WOText area". Now
you show a WOString. WOText and WOString are very, very different.
Being precise in your questions will yield more exact answers more
quickly.
I seem to recall an example method.
inside my HTML
<webobject name = "NotesRowRepetition">
<tr align = "left">
<td><wo:WOString value = "$currentNote.noteText" /></td>
</tr>
</webobject>
and the WOD:
NotesRowRepetition: WORepetition {
list = notesDG.displayedObjects;
item = currentNote;
}
so that currentNote is from a 'to-many' relationship. I need to
escape the currentNote.noteText for \n
I just don't see how.
java.text.Format. Get familiar with it, it is a very useful tool. I
covered this in my Best Practices session at WOWODC 08.
Here is a simple example
/**
* Converts \n to <br/> on output
*/
public class HTMLLineBreakReformatter extends java.text.Format {
public StringBuffer format(Object object, StringBuffer buffer,
FieldPosition position) {
return buffer.append(((String)object).replaceAll("\n", <br/>));
}
}
Create an instance in your page and use the formatter binding of
WOString.

Hi!
That shouldn't be needed in text
areas... my guess is some kind of line feed representation
problem. Mac (classic), Windows and UNIX all use different
representations for line feeds. I don't recall what the
browser uses, but it's probably different than what you
have in the DB.

How about using
string.replace("\n", "<br/>")

I have text from my database that has returns (line
feeds). If I just bind the text to a WOText area, the CRs
and LFs are ignored.
Can someone point me in the right direction.
I need to convert the CR to <BR />...
