Environment (JDeveloper 11.1.2.0.0, ADF Faces)
In the last post, I have explained how to show af:message programatically. In some cases the user may need to show a multi-lines message, in this post I will explain how to do this.
af:message allows us to include a formatted text in the message, this can be done by surrounding the message text with <html> tags. So to show a multi-lines message, we can use <p> tag in our message text. The method below displays three lines message.
public String shwoMultiLinesMessage() {
StringBuilder builder = new StringBuilder(“<html> <body>”);
builder.append(“<p>First Line</p>”);
builder.append(“<p>Second Line</p>”);
builder.append(“<p>Third Line</p> “);
builder.append(“</body> </html>”);
FacesMessage fm = new FacesMessage(builder.toString());
fm.setSeverity(FacesMessage.SEVERITY_INFO);
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, fm);
return null;
}
The result is af:message with three lines as shown in the image below:
multi-lines message
How to set height and width of af:messages window?
It do not auto re-size unlike dialog box?
Unfortunately I have no idea about that.
This question has been discussed in OTN by Chris Muir who is an Oracle ADF Product Manager.

but it seems there is no answer until now.
It is better to re ask the question in Jdeveloper and ADF forum
