How to retain selected value in dropdown list...

[damonchong]

First and foremost, thanks for any assistance and advice!

I have created a drop down box as below:

<h:selectOneMenu id="orgTypeSelect" value="#{addStrainCtrl.organism}" required="true">
 <s:selectItems value="#{organismTypes.resultList}" var="organismType" label="#{organismType.description}" noSelectionLabel="Please Select..." />
 <s:convertEntity />
</h:selectOneMenu>

However, I realise if there is any errors during the processing of the submitted form and the user is re-directed to the same form for a chance to correct their "mistakes", the value they selected in the drop down box is reset to "Please Select...". This behaviour is not happening for input text box using the <h:inputText> tag though.

I cracked my brain for a few days now trying to figure out the missing ingredient...it shouldn't be something extremely difficult, i hope ;-)

Appreciate any help and thanks!

This should work (see the UI example for instance).

You're probably going to have to use your debugger here as I have no idea why this would happen.

Is the key id of your entity bean an object e.g. of type Long? If so, maybe it helps when you overwrite the equals and hashCode method in the entity class. This was the only thing that helped me (under 2.0.0.CR3) when I used s:convertEntity to assign the selected item to the object in the list.

Hehe, silly me.....sometimes it takes an assurance from the expert just to make one try harder. My mistake was to do a redirect (although back to the same page) upon error. Instead, i should just return a null and let seam takes care of restoring the values.

Thanks guys!
