Problem in populating values in dropdown by key

[Former Member]

Hi All,

I have three dropdowns DD1,DD2 and DD3.If i select one value in DD1 basing on that selected value the respective values need to be populated in the other two dropdowns DD2 and DD3.This functionality is working fine but if i select a new value in the DD1 the old values are not getting refereshed in DD2 and DD3 the new values are getting populated but the old values are displayed.

I invalidated the nodes that i binded for both the dropdowns but still the old values are not getting refereshed can you help me in this issue.

Thankx,

hi,

you do the coding for populating the values to DD2 and DD3 in the onselect action of DD1.

and invalidate the nodes before populating the new one

Thanks and Regards

Hi Nazz,

Check the node binding to 2nd and 3rd UI and Singleton property.

Also check the place in which u call invalidate method in the code.

Make sure that u r deployments r correct.

hi

what is the code u have written for invalidating the nodes ?

if you can provide the code i can help you ?

Hi,

It should work if you invalidate both the context nodes of DD2 and DD3 in the action of DD1. Give it one more try.

Thanks,

Hi Chander Kararia,

No DD2 and DD3 do not have any values in it.They will get displayed only after selecting the first drop down.

Thankx,

Hi Naaz,

As you said, DD2 & DD3 does not have any values. So, from that what I understand is:

1. If you select value "A" in DD1, corresponding "A2" will be populated in DD2 & "A3" in DD3.

Right?

2. Now, if you again select value "B" in DD1, corresponding "B2" SHOULD be populated in DD2 & "B3" in DD3. Right?

3. So, is it like

ARE YOU APPENDING THE VALUES IN DD2 & DD3 (i.e. creating a list in both drop downs) and WANT TO DISPLAY THE LAST SELECTED CORRESONDING VALUES ?

or,

ARE YOU JUST INTRESTED IN DISPALYING THE CORRESPONDING VALUES IN DD WITHOUT HOLDING THE LAST VALUES IN DD2 & DD3?

Hope I am clear.

Hi Naaz,

As you said, on the basis of 1st dd value, dd2 & dd3 values need to be set.

So, do dd2 & dd3 already having some values that need to be just displayed now as selected?

or, dd2 & dd3 will add the new values in the list & display them now as selected?

This willl help in answering.

Also, check dd2 & dd3 cardinality.
