0gnl-2.7.1-SNAPSHOT bug... please help
Folks,
My java code is fine... this template keeps failing. It seems OGNL cannot
negotiate/articulate propertyDescriptor for my contrib:table column.
<span jwcid="$content$">
<table jwcid="table">
<div jwcid="linkColumnValue@Block">
<a jwcid="editLink@EditLink" model="ognl:object" href="#">
<span jwcid="linkInsert@Insert"
value="ognl:object[#this.linkProperty]"/></a>
</div>
<div jwcid="blobColumnValue@Block">
<span jwcid="@TrailsDownload"
propertyDescriptor="ognl:column.propertyDescriptor"
model="ognl:object"
bytes="ognl:object[#this.column.propertyDescriptor.name]"
/>
</div>
</table>
</span>
This is the problem component... blobColumnValue@Block
This is the problem line propertyDescriptor="ognl:column.propertyDescriptor"
Any attempts to reference PropertyDescriptor produce bindingexception.
Stack trace below...
Does anyone know of an OGNL workaround? OGNL seems to work ok if I omit the
second block. It does not seem to be able to operate across blocks.
Thanks for your attention. Just really stuck.
Best regards
Ken in nashua
