java.lang.Long, which does not inherit from java.lang.String?
Sorry guys,
In b3 this worked fine.
I know Long does not inherit from String but where does this come from?
The getField2bEdited() only retrieves the value (in this case a Long) and
sends it away (as usual).
Parameter value (0) is an instance of java.lang.Long, which does not
inherit from java.lang.String.
binding: ExpressionBinding[TreeTableTestFlexible field2bEdited]
location: classpath:/org/dcg/tests/treetable/TreeTableTestFlexible.page,
line 144
Stack Trace:
*
org.apache.tapestry.binding.AbstractBinding.getObject(AbstractBinding.java:270)
* org.apache.tapestry.form.TextField.readValue(TextField.java:77)
Debugger gives a Long with value 0. fieldName.toString() yields a String
with value 0.
Any suggestions?
TIA

Someone else had exactly the same problem yesterday. I am not sure how
this worked in b3 but per specification this is not supposed to work.
TextField can only be bound to String properties. Other types can only
be enforced with the ValidField and an appropriate validator AFAIK.
