Expression and .tld file

Question

Hello everyone,
i created custom component and i am using it in my application, where in main.jsp i have :
<taglib1:RasterTag value="#{row.RasterB}"/>
taglib1 is a .tld file, where i have tag RasterTag with attribute value. In main.jsp i set value ="#{row.Raster}". row.Raster refer to a row from column Raster in database.
in .tld file i have:
<tag>
<description></description>
<display-name>RasterTag</display-name>
<name>RasterTag</name>
<tag-class>component.RasterTag1;/tag-class>
<body-content>empty</body-content>
<attribute>
<name>value</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
<deferred-value>
<type>java.lang.String;/type>
</deferred-value>
</attribute>
when i set value = "somestring" everything works ok, but when i specified expression value ="#{row.Raster}" nothing is returned because my component didnt get value of expression.
does anyone know, how should i specified value in .tld file, to accept and get strings from expression?
Thank you
Katka

Answer 1

should be using the format "prefix : function name". Notice the use of the colon instead of the period.
