F4 help not being Displayed, it gives a null pointer exception

[vinay_baji2]

HI,

My requirement is to get an f4 help, for an input field in a table. I am getting a null pointer exception, for the following

IWDAttributeInfo ctrInfo =
	wdContext.getNodeInfo().getAttribute(IPublicDc_Proj_Partnerfunction.IChldElement.PF);  

i Have tried placing it outside the child element too,

Pls help

Thanks a lot Shruti!!

I got a solution from the code i was trying, there was a similar post on sdn.

The solution being

Try to change

wdContext.getNodeInfo().getAttribute(
IPrivateApplicantCompView.IApplicationElement.TITLE
);

to 
wdContext.nodeApplication().getNodeInfo().getAttribute(
IPrivateApplicantCompView.IApplicationElement.TITLE
);

Refer to [;

Thank you once again

Vinay

Hi Shruti,

The values are being loaded manually, the requrement is to get the values in a look up,. for the time being we are loading it manually, (plan to change it to dynamically later on).

the present way i am filling the data is

 IPublicDc_Proj_Partnerfunction.IPartnrFuncElement ele= null;
IPublicDc_Proj_Partnerfunction.IPartnrFuncNode node=wdContext.nodePartnrFunc();
ele=node.createPartnrFuncElement();
ele.setPartnerfunctn("val1");
ele.setPF("PF1"); 
node.addElement(ele);
ele.currentChldElement().setPF("PF1");
ele=node.createPartnrFuncElement();
ele.setPartnerfunctn("val2"); 
ele.setPF("PF2"); 
node.addElement(ele);
ele.currentChldElement().setPF("PF2");

Vinay,

you can use the follwoing code after populating PartnrFunc node.

ISimpleTypeModifiable nType1 = wdThis.wdGetAPI().getContext().getModifiableTypeOf(ContextAttributeName bound to inputfied);
IModifiableSimpleValueSet value1 = nType1.getSVServices().getModifiableSimpleValueSet();
for(int i=0;i<size();i++)
{
 l_searchEle1  = wdContext.nodePartnrFunc().getPartnrFuncElementAt(i);
 value1.put(l_searchEle1.getPF(),l_searchEle1.getPartnerfunctn());
}

I guess the above code should work.

Regards Shruti.

Hi shruti, the nodeSearcHelp is not being displayed/ accepted please could you help me out a bit further

Hi Vinay,

nodeSearch is the i had used in my code.

You need to actually acces the data in for loop which you want to populate as F4 Help.

The example i have sent you in that data is being populated from one node.

Let me know in case of further clarification or else you can explain your scenario how you are populating F4 values.

Regards Shruti.

[vinay_baji2]

does it in some way depend on cardinality? the cardinality for the child node is 0..1

Hi Vinay,

You can try this code.

ISimpleTypeModifiable nType1 = wdThis.wdGetAPI().getContext().getModifiableTypeOf(ContextAttributeName);
IModifiableSimpleValueSet value1 = nType1.getSVServices().getModifiableSimpleValueSet();
for(int i=0;i<size();i++)
{
 l_searchEle1  = wdContext.nodeSearchHelp().getSearchHelpElementAt(i);
 value1.put(l_searchEle1.getCode(),l_searchEle1.getName());
}

Regards Shruti.
