TableFilter.java NullPointerException

[nikhil_bose]

Using TableFilter.java from /people/peter.vignet/blog/2007/01/03/generic-web-dynpro-java-table-filter blog, on running the application it shows

{color.blue}java.lang.NullPointerException

at com.sap.demos.table4.TableFilter.setFiltersForColumns(TableFilter.java:117)

at com.sap.demos.table4.TableFilter.init(TableFilter.java:71)

at com.sap.demos.table4.TableFilter.<init>(TableFilter.java:48)

at com.sap.demos.table4.Table4_ComponentsView.wdDoModifyView(Table4_ComponentsView.java:145)

at com.sap.demos.table4.wdp.InternalTable4_ComponentsView.wdDoModifyView(InternalTable4_ComponentsView.java:447)

What could be wrong?

thanks in advance,

nikhil

Hi,

have you changed the value "null" in thw doModify method to new HashTable();

//@@begin wdDoModifyView

if (firstTime ) {

IWDTable table = (IWDTable) view.getElement("Table");

wdContext.currentContextElement().setTableFilter( new TableFilter(table, wdThis.wdGetFilterAction(), //wdContext.nodeSource(),null));

//change it to new HashTable();

wdContext.nodeSource(),new Hashtable();

}

//@@end

}

thanks and regards

Hi Nikhil,

It will be helpful for all if you can open TableFilter.java and copy code at line number 117 here in forum.

Gopal,

This is no change in TableFilter.java. Change is needed where we initializing the TableFilter().

In Dynpro, we are setting TableFilter context object to TableFilter Object.

And fazal has the change as bold. Look at his post

again, thanks fazal
