Subject RE: PLEASE HELP: How would I use the iterate tag here? Where are you Craig McClanahan?
Date Thu, 01 Mar 2001 00:14:47 GMT
I have tried both of the ways below without any luck:
--------------------------------------------
<logic:iterate id="supplier" name="user" property="suppliers" >
<TR>
<TD><FONT face = "Arial"><bean:write name="supplier" property="value.code"/></FONT></TD>
<TD><FONT face = "Arial"><bean:write name="supplier" property="value.name"/></FONT></TD>
<TD><FONT face = "Arial"><bean:write name="supplier" property="countryName"/></FONT></TD>
</TR>

</logic:iterate>
--------------------------------------------
and I have tried this:
--------------------------------------------
<logic:iterate id="supplierMapEntry" name="user" property="suppliers" >
<bean:define id="supplier" name="supplierMapEntry" property="value" type="com.motorola.mms.msqc.beans.SupplierBean"/>

<TR>
<TD><FONT face = "Arial"><bean:write name="supplier" property="code"/></FONT></TD>
<TD><FONT face = "Arial"><bean:write name="supplier" property="name"/></FONT></TD>
<TD><FONT face = "Arial"><bean:write name="supplier" property="countryName"/></FONT></TD>
</TR>

</logic:iterate>

You should be able to use nested properties:

<bean:write name="item" property="value.code"/>
<bean:write name="item" property="value.country"/>
<bean:write name="item" property="value.countryName"/>
