problematic tag?
I have a html:options collection where the beans have a deep
hierarchy. I'd like to set the labelproperty of my html:options
to one of the bean's property like
mybean.getCustomer().getParent().getName();
how can I do this with html:options. Does it suport
expression language?
The EL
This:
html:option value=${emailGroup.emailGroupID}
produces this:
option value=${emailGroup.emailGroupID}
instead of this:
option value=17
Are you sure the html prefix references the EL version of the taglib?
