Subject RE: Multiple <logic:iterate> still unclear
Date Tue, 17 Sep 2002 12:40:49 GMT
It seems that it was a syntax error coupled with a lack of some struts
fundamentals that lead me down this road. I had the following:
	<logic:iterate id="aAuthor" name="aBook" property="authorIds"/>
		<bean:write name="aAuthor"/><br>
 	</logic:iterate>
Note the '/' on the logic:iterate tag. When this present only the last
element in my List would display. I knew it had to be something dumb.
Thanks all for your help on this.

I tried adding the length attribute:

<logic:iterate  id="aBook" name="allBooks">
     <bean:write name="aBook" property="id"/><br>
     <bean:write name="aBook" property="desc"/><br>
     <logic:iterate id="aAuthor" name="aBook" property="authorIds"
length="6">
        <bean:write name="aAuthor"/><br>
     </logic:iterate>
 </logic:iterate>

This displays the 6th element in the List. I have tried many variations
of this and yet still can not seem to iterate over and display the
contents of the List object. I have verified that the List is populated.
I know the answer is going to be so simple, I just can not see it right
now. Anyone know what the correct syntax should be?

Steve,

There is a "length" attribute on the logic:iterate tag. You can set it
as a hard value or, in the case of your bean containing a list, get the
size(), set a page scoped var and do portions of the iteration.
