Is this a typo? If not, it is probably your problem.
>> <html:select property="customer" size="1">
>> <html:options property="customers"/ labelName="value"
>> labelProperty="key">
>> </html:select>
Should be:
<html:select property="customer" size="1">
<html:options property="customers" labelName="value" labelProperty="key"/>
</html:select>
Backslash denoting end of element in wrong place.
Besides that, I use the 'collections' attribute of html:options, and don't
use labelName. Example:
<html:select property="typeId">
<html:options collection="typecollection" property="id"
labelProperty="name"/>
</html:select>
In this case, 'typecollection' is a Collection of objects that have getId()
and getName() methods. The return of these methods will be used to populate
the drop-down list. The 'property' attribute of the html:select element
denotes which option to select by default (that is, to add the 'selected'
attribute to). This is determined by calling the method of the form bean
denoted by the 'property' attribute. In other words, when the return of
[form_bean].getTypeId() matches [typecollection].getId(), the option would
be 'selected'.
Use case: in the case that three objects in 'typecollection' had ids of
1,2,3 and names of name1,name2,name3, and the [form_bean].getTypeId()
returns 2, this would be the output:
<select name="typeId"><option value="1">name1</option>
<option value="2" selected>name2</option>
<option value="3">name3</option></select>
Hope this helps,
