Passing form property into custom tag

[Brian Bowman <br...@nordicwave.com>]

This has got to be very simple but I can't figure it out. All I want to do
is pass a form bean property as an attribute value to a custom tag. My
custom tag is called decode and it just converts a code(in this case
country) into a full name. The code comes from the form associated with this
page(in this case itemForm).

I have tried this:
<app:decode codeType="country" code="<bean:write name='itemForm'
property='countryCode'/>"/>

and this
<app:decode codeType="country" code='<bean:write name="itemForm"
property='"countryCode'">'/>

and they both give me the string <bean:write name="itemForm"
property='"countryCode'"> as the code attribute value in the custom tag.

I know "bean:write" probably isn't correct but I don't know what else to
try.

I have the tag defined as the following in my app.tld:

	<tag>
		<name>decode</name>
		<tagclass>com.nordicwave.resourcing.web.taglib.DecodeTag</tagclass>
		<bodycontent>empty</bodycontent>
		<info>

      Decode a code from the code table based on the

      parameters provided:

      codeType - type of code in the code table

      code - code from code table</info>
		<attribute>
			<name>codeType</name>
			<required>true</required>
			<rtexprvalue>false</rtexprvalue>
		</attribute>
		<attribute>
			<name>code</name>
			<required>true</required>
			<rtexprvalue>true</rtexprvalue>
		</attribute>
	</tag>


Any help would be greatly appreciated.

Thanks in advance,

You cannot nest taglibs within each other.  (A taglib cannot be an
attribute for another taglib).
However, you could retrieve the countrycode value as a script variable,
and then use that as the attribute of the <app:decode>  taglib.
The <rtexprvalue> value for the code attribute of decode must be TRUE
for this to work...

<% String countryCode = theValue;  %>
<app:decode codeType="country" code="<%=countryCode%>">
