Pardon me for jumping into this thread... Once you use bean:define, is it possible to change the value? I wanted to use bean:define like this:
<bean:define id="resultsEmpty" value="true"/> <logic:iterate id="code" name="myForm" property="codeList" type="Foo"> <bean:define id="resultsEmpty" value="false"/> <bean:write name="code" property="desc"/> </logic:iterate> <logic:equal property="resultsEmpty" value="true"> No records found. </logic:equal> This didn't work. It barfed on the second bean:define, but I have a feeling the logic:equal won't work either.

Since your tag is just writing out the value, you need to capture that value first, by defining a bean for it. Since the value of your output will never be null, you cannot use <logic:present> to check it; you need to use <logic:empty> instead. -- Martin Cooper > -----Original Message----- > From: Tejas Bavishi [mailto:[EMAIL PROTECTED]] > Sent: Friday, September 20, 2002 8:55 AM > To: '[EMAIL PROTECTED]' > Subject: Logic tag > > > Hi, > > I have a question on using logic tags. > > In the following example, mytaglib is the tag library > developed by me.
