Action method not being called

Question

Using jdev 10.1.3.4 with jsf/adf bc. I have two af:table components on a jsf page. I'll call them table A and table B. In table B, I have an input text with autosubmit=true and hooked up to a valuechangelistener. One of the columns in table B is a command button. Initially, I was having problems when the user changed the input value in table B and then immediately clicked the button in table B. Sometimes when the button was clicked, the backing bean method associated with it was not executing. Thanks to Didier's advice in this forum (Re: PPR and submit I was able to get this functionality working consistently.
I still have a problem though. Table A has a command LINK as one of the columns, which executes a method in the backing bean when clicked. However, as in the scenario above, if the user changes a value in the input text in table B and in this case immediately clicks the LINK in table A, it seems that the action method behind the button in table A executes the first time but if user repeats steps (changes value of input in table B and immediately clicks LINK in table A) the action method is not called after the first time. For testing, there is no real code in the backing bean method. The only code in the action method is an sop so I can tell if the method was executed. Likewise, the value change listener method, for testing purposes, has a sop so I can tell if/when it is executed and the thread.sleep(400) code needed per Didier's workaround. I'll include the code from jspx:
In the jspx -
<afh:body firstClickPassed="true">
<h:form>
<!-- table A -->
<af:table value="#{bindings.Summary.collectionModel}" var="row"
rows="#{bindings.Summary.rangeSize}"
first="#{bindings.Summary.rangeStart}">
<af:column headerText="#{bindings.Summary.labels.PositionNbr}">
<af:inputText value="#{row.PositionNbr}"/>
</af:column>
<af:column>
<af:commandLink text="Click" action="#{backing_levelone_untitled2.buttonClicked}"/>
</af:column>
</af:table>
<!-- Table B -->
<af:table value="#{bindings.BdCommentsView.collectionModel}" var="row"
rows="#{bindings.BdCommentsView.rangeSize}"
first="#{bindings.BdCommentsView.rangeStart}">
<af:column headerText="#{bindings.BdCommentsView.labels.CommentId}">
<af:inputText value="#{row.CommentId}"
required="false" />
</af:column>
<af:column headerText="#{bindings.BdCommentsView.labels.Comments}">
<af:inputText value="#{row.Comments}"
required="false" autoSubmit="true" valueChangeListener="#{backing_levelone_untitled2.isValid}"/>
</af:column>
<af:column>
<af:commandButton text="Click" action="#{backing_levelone_untitled2.buttonClicked}"/>
</af:column>
</af:table>
</h:form>
</afh:body>
I need the backing bean method behind the LINK in table A to be fired consistently, every time user makes a change to input of table B and immediately clicks LINK in table A. It works the first time, but all subsequent attempts will not result in the action method being executed. Hope someone can help.

Answer 1

I'm not sure if this is considered a bug, but I found that if I use a commandLink in table A, my code doesn't work as expected. However, I found that by using a commandButton in table A the functionality works as expected. I still would like to hear some feedback on this if anyone is interested in recreating the scenario. Thanks.
