Null pointer error in Table drop down after EP 7.3 upgrade

[Former Member]

Hello All,

We are migrating from EP 6.0 to EP 7.3. Old WDJ applications has table UI with drop down by index editor. After deploying to EP 7.3 everything else works fine,

Except for this drop down in table column. When I select drop down value it fails with following error.

java.lang.NullPointerException: while trying to invoke the method com.sap.tc.webdynpro.progmodel.context.NodeInfo.getParentInfo() of an object loaded from local variable 'nodeInfo'

    at com.sap.tc.webdynpro.progmodel.context.Paths.getNodeFor(Paths.java:609)

    at com.sap.tc.webdynpro.clientserver.uielements.adaptbase.AbstractAdapter.updateLeadSelection(AbstractAdapter.java:1506)

    at com.sap.tc.webdynpro.clientserver.uielib.standard.uradapter.TableAdapter._changeLeadSelection(TableAdapter.java:30516)

    at com.sap.tc.webdynpro.clientserver.uielib.standard.uradapter.TableAdapter.access$11800(TableAdapter.java:251)

    at com.sap.tc.webdynpro.clientserver.uielib.standard.uradapter.TableAdapter$Rows._setLeadSelectedElement(TableAdapter.java:22226)

Table data source is binded to a dummy node e.g. node A with (1:1 , 0:1) so that table will always have one row. Table has two columns which are directly binded to fields from other nodes (not data source node of table) e.g. node B->amount attribute. When we select new value from drop down select event is called on drop down cell which tries to find lead selection for table data source node A. As both node B and Node A has no connection, standard logic fails with above error.

In a second try, I moved node B under node A, with B having singleton property false, even this failed for me.

In a Third attempt, I created fresh application recreated first and second scenario, everything works fine there.

Then I copied all new context from new application to migrated WDJ application and it fails with the same error.

So this scenario works fine in new application but fails in old application. Has anyone faced this issue?

Hi all,

I solved this issue. You must put in your Table -> General -> Properties -> CompatibilityMode the value "nw04Plus".

Regards.
