Dear All:
I haven't received feedback for this, I apologize for sending it again
but hopefully someone can give me
an advice. Thanks so much!
I'm using Struts 1.3.5 in my content management web application. I have
a form with a dynamic
list. To validate it, I used the following in my validator.xml to loop
over all elements of the
list "childrenForm" of my main form:
<field property="name" depends="required,minlength,maxlength"
indexedListProperty="childrenForms">
<msg name="required" key="error.catalog.collection.null"/>
<msg name="minlength"
key="error.catalog.collection.minlength"/>
<msg name="maxlength"
key="error.catalog.collection.maxlength"/>
<arg position="0" name="required"
key="catalog.editItemForm.itemForm.name.label"/>
<arg position="1" name="required"
key="catalog.editItemForm.childrenForms.label"/>
<arg position="0" name="minlength"
key="catalog.editItemForm.itemForm.name.label"/>
<arg position="1" name="minlength"
key="catalog.editItemForm.childrenForms.label"/>
<arg position="2" name="minlength" key="${var:minlength}"
resource="false"/>
<arg position="0" name="maxlength"
key="catalog.editItemForm.itemForm.name.label"/>
<arg position="1" name="maxlength"
key="catalog.editItemForm.childrenForms.label"/>
<arg position="2" name="maxlength" key="${var:maxlength}"
resource="false"/>
<var>
<var-name>minlength</var-name>
<var-value>3</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>20</var-value>
</var>
</field>
Right now, this will show the same error message for all elements, if
their name is not in the submitted
form. Furthermore, the same message may be shown multiple times with
<html:errors/>, if multiple names
are not filled out by the user). However, I would like to customize the
error message per element of the list,
and say something like
Your field 'Name' for Category #2 ('Mathematics') is required. Please
enter a Name.
Here 'Mathematics' is the actual field's name property and index is the
index of it in the list (or
the index plus 1, say).
- Is there a way to use something like 'childrenForm[].name' as the
value of <arg position="2">,
instead of using a key? I know it's possible to reference '[]' in the
variable 'test', but not in any other variable.
- Is there a way to reference the index of the element in the list in an
error message?
- Is there a way to reference an expression that depends on the index,
like an EL expression (e.g. "${index+1}")?
Thanks so much in advance,
Oren
