Auto-Submit On Change in DropDown List not working properly!

Question

Hi all,
I�ve got a problem with a drop down list an a table with some rows on my page. The property "Auto-Submit on Change" is set for the drop down because the valueChange-method has to do some work when the user selects another value from the drop down.
The problem is that after selecting another item from the drop down, the table fields don�t keep their values, which I had entered before I selected another item in the drop down. But: When I select an item again, suddenly exactly these values are set.
Here my code:
<?xml version="1.0" encoding="UTF-8"?>

</ui:tableColumn>
<ui:tableColumn binding="#{Page1.tableColumn3}" headerText="field3" id="tableColumn3" sort="field3">

</ui:tableColumn>
<ui:tableColumn binding="#{Page1.tableColumn4}" headerText="field4" id="tableColumn4" sort="field4">

<ui:textField binding="#{Page1.textField5}" id="textField5" text="#{currentRow.value['field5']}"/>
</ui:tableColumn>
<ui:tableColumn binding="#{Page1.tableColumn6}" headerText="field6" id="tableColumn6" sort="field6">
<ui:textField binding="#{Page1.textField6}" id="textField6" text="#{currentRow.value['field6']}"/>
</ui:tableColumn>
</ui:tableRowGroup>
</ui:table>
<ui:dropDown binding="#{Page1.dropDown1}" id="dropDown1" items="#{Page1.dropDown1DefaultOptions.options}"
onChange="common_timeoutSubmitForm(this.form, 'dropDown1');"
style="position: absolute; left: 48px; top: 24px; width: 240px; height: 24px" valueChangeListener="#{Page1.dropDown1_processValueChange}"/>
</ui:form>
</ui:body>
</ui:html>
</ui:page>
</f:view>
</jsp:root>
and the code of the valueChange-Method:
public void dropDown1_processValueChange(ValueChangeEvent event) {
getSessionBean1().getColumnProvider().commitChanges();
List positions = getSessionBean1().getColumnProvider().getColumnList();
Is there some explanation for this behavior or it�s really a bug in the way how the drop down is submitting the form? I would understand it when commitChanges is not working here because of auto submit on change (==immediate?). but once it works und once it doesn�t work!

Hi There,
Not sure what you mean. Have you tried Netbeans 6 yet. Do you see same behaviour in it as well?
This might be of help to you
