---------------------------------------
Hi Rainer,
I think this introduced a bug.
- I have a page with a d:record
- this record is a record of table A
- I use a few d:controls in that record tag
- I have a data table with data from table B
- I use a few d:value tags with column="db.B.COL" value="#{item.col}"
- After that I have a few e:value tags - again for table A, eg e:value
column="#{db.A.FOO}" (no record=)
Until now that worked - the record was obtained from the record tag. Now I got
the error:
{code:java}
java.lang.NoSuchMethodException: Unknown property 'foo' on class 'class
ch....TableBListEntry'

It looks like it wants to use the value from the datatable, not from the record
A workaround is to use record="" in my value. But I don't think it should be
like this?
Can you take a look at that?
