ADF/JSF page loads when any command button is clicked

Question

Hello All,
I am lost in the ADF/JSF page flow (using Jdev 10.1.3). Following are the tags (in order) in my page;
(WHEN THIS PAGE LOADS, IT GOES TO THE DATABASE TO GET VALUES (for the drop down lists that will appear on the page); THIS SHOULD HAPPEN JUST ONCE AND AT THIS POINT)
<f:view>
<afh:body>
<afh:html>
<af:form>
<af:panelpage>
<f:facet name="contextSwitcher">
<af:panelHorizontal> has a af:commandLink </af:panelHorizontal>
</f:facet>
<f:facet name="messages">
<af:messages/>
</f:facet>
<af:panelform>
<h:panelGrid columns="2" cellspacing="14">
has 2 panelgroups (one group has *2 SelectOneChoice lists (that need to be populated by fetching data from database* and the other group has 2 CommandButtons - 'Go' and 'Cancel") (GO BUTTON SETS THE SHOWPANEL() TO TRUE)
(WHEN GO BUTTON IS CLICKED, THE PAGE GOES TO THE DATABASE (AS IT DID ON PAGE LOAD). *THIS SHOULD NOT BE HAPPENING*. ONLY THE METHOD (action="#{muBean.doWork}" )THAT IS ASSOCIATED WITH GO BUTTON ACTION SHOULD BE CALLED)
</h:panelGrid>
<h:panelGrid columns="2" cellspacing="14" rendered="#{myBean.showPanel}"> (THIS ONE IS RENDERED WHEN SHOWPANEL() METHOD IS TRUE)
has 3 inputText fields
</h:panelGrid>
<af:table var="someTable" rendered="#{myBean.showPanel}"> (THIS ONE IS RENDERED WHEN SHOWPANEL() METHOD IS TRUE)
has a bunch of af:columns
</af:table>
<af:panelHorizontal rendered="#{myBean.showPanel}"> (THIS ONE IS RENDERED WHEN SHOWPANEL() METHOD IS TRUE)
has 3 af:commandButtons - submit, save, add row
(WHEN submit or save or add row BUTTON IS CLICKED, THE PAGE KIND OF LOADS AND GOES TO THE DATABASE (AS IT DID ON PAGE LOAD). *THIS SHOULD NOT BE HAPPENING*. ONLY THE METHOD THAT IS ASSOCIATED WITH submit/save/add row BUTTON ACTION SHOULD BE CALLED)
</af:panelHorizontal
</af:panelForm>
</af:panelPage>
<!-- Footer -->
<jsp:include page="/pages/includes/footer.jspx"/>
</af:form>
<f:verbatim>
<script type="text/javascript" src="../script/tree.js"></script>
</f:verbatim>
</afh:body>
</afh:html>
</f:view>
</jsp:root>
_*why is it that when the command buttons are clicked, the whole page is loaded? Only the methods associated with the action (action="#{newMapRequestItem.addARow}" ) should be called.*_
_*IS THERE A WAY TO AVOID THIS WITHOUT USING PARTIAL PAGE RENDERING ?*_
_*DOES MY TAG NESTING LOOK OK?*_
