Sorry Matt,
I guessed i had done a copy-paste on that post. In the code i did used your
suggested code.
I have done some experiment on this..
My Model contains:
private Long hostelSessionId;
private String residenceNo;
// with setters & getters
By ommiting the form:option, the screen can be loaded and the dropdown able
to pre-select existing value behind the model.
<form:select path="hostelSessionId">
<form:options items="${sessionList}" itemValue="value" itemLabel="label"/>
</form:select>
Same result with form:select only
<form:select path="hostelSessionId" items="${sessionList}" itemValue="value"
itemLabel="label">
</form:select>
However, if i add form:option between the form:select. The screen is not
loaded at all, even though from the log, i can see that my backingObject
contains value for that particular attribute.
After that, i tried using attribute type String to hold the Long value
(after converting to string)
<form:select path="residenceNo">
<form:option value="-" label="--Please Select Session--"/>
<form:options items="${sessionList}" itemValue="value" itemLabel="label"/>
</form:select>
And it works like nothing went wrong :confused:.
Until i realized that my form:option default value is "-" which i think the
initBinder will not be able to recognize or to parse this, since my
hostelSessionId is Long type. Thus, by replacing it with empty or "0".. my
original form:select is working fine finally.. =^D
<form:select path="hostelSessionId">
<form:option value="0" label="--Please Select Session--"/>
<form:options items="${sessionList}" itemValue="value" itemLabel="label"/>
</form:select>
So, does my theory on this is correct? Any good advice?
Thanks
