Dynamic value in a Tag

[Marco Miedl <ma...@miedlnet.de>]

Hi,

I want to initialize the fields of a Struts Form with the <html:text>-Tag.
In my request there is a bean with the getter and setter I need.
Now I tried this:

<html:text value="<bean:write name="myLink" property="URL"/>" property="URL" size="25" maxlength="256"></html:text>

and I got the following Error:

org.apache.jasper.JasperException: /linkothek/LinkChange.jsp(36,58) equal symbol expected
 at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:94)
 at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:428)
      ..........

When I try to use the Tag: <bean:write name="myLink" property="URL"/>  alone (not in another Tag) then I got value I should get. So I see that the bean is in my Request. But why doen't it work when I put the <bean:write> Tag into the <html:text> tag?
I think this is a problem a lot of others also have, because you often need to initalize the values of Form Elements with dynamic content.

Can somebody help me?

Greetings and THANX in advance
    Marco

Why don't you initialize your fields inside your action or inside the
reset method of your form?

Try something like:

<bean:define id="value" type="String" name="myLink" property="URL"/>

<html:text property="URL" value="<%= value %>" ... />
