Problem getting jsp component from jspdynpage

Question

Hi,
  I am making a call in my java class in method
doProcessBeforeOuput with the following call
table = (TableView) this.getComponentByName("tableview_AddMaterial");
Object[] objs = this.getComponents();
Both return nulls for the object, how does someone access the jsp tables or text fields defined by id in htmlb in your java code I did check and all these are defined
private IPageContext pageContext;
private IPortalComponentRequest request;
private IPortalComponentResponse response;
private IPortalComponentSession session;
private IPortalComponentContext userContext;
private IPortalComponentProfile userProfile;
Also here is my htmltable in the jsp
<hbj:tableView
id="tableview_AddMaterial"
model="DHB.queryResultsModel"
design="TRANSPARENT"
headerVisible="false"
footerVisible="true"
visibleRowCount="50"
visibleFirstRow="1"
selectionMode="MULTISELECT">
</hbj:tableView>
Any help would be greatly appreciated and I do reward points for helpful answers
Cheers,
Devlin

Hi Devlin
You can access the fields in jsp as follows.For example, consider tableview with id "myTableView".
<b>TableView table = (TableView) this.getComponentByName("myTableView");</b>
If you add this line, you can get all the values related to tableview.For example, to get the first visible row of the tableview, the code goes as follows.
<b>int firstVisibleRow = table.getVisibleFirstRow();</b>
Jsp for the same:
==================
<hbj:tableView
                    id="myTableView"
                    model="tablebean.model"
                    design="ALTERNATING"
                    headerVisible="true"
                    footerVisible="true"
                    selectionMode="MULTISELECT"
                    headerText="Office locations"
                    visibleFirstRow="1"
                    visibleRowCount="5"
                    rowCount="16"
                    width="500px">
               </hbj:tableView>
Try and let me know the results.
Hope this helps.
