ValueHelp Refresh

[Former Member]

Hi ,

This is on Webdynpro java. I am using NWDS7.0.

To create a new record in R3. I have created 3 value helps (EVS) which fetch data from bapi. i have used 3 input fields. i have successfully created the data in R3. but the problem what i am facing is, when i close the window for creating the record and again open the window, the previous values from the bapi stay as it is in the value help button which i dont want. how can i refresh them. i have even invalidated the node where i store the value help attributes but of no use. (FYI: the requirement is such that 2nd input field value_help values comes only after selecting the 1st input fields valule_help and pressing enter by the user and 3rd input field value_help values comes only after selecting the 2nd value_help input field value). when i refresh the browser, the problem is resolved but the client does not need this. Any help from the webdynpro techies is highly appreciated.

Thanks

Hi,

It looks like you have used a Node to bind the value to the EVS. Try using a context attribute to bind to the EVS value property. Then it will automatically clear the value once u close the window.

Do let me know if you face any problems.

Hi Poojitha,

Thanks for quick reply. it does not matter whether an attribute or a node. At code level the value_help values are getting refreshed but at page level they are in the cache. so what i did was after writing this line of code

IModifiableSimpleValueSet vhm1 = vhsimp1.getSVServices().getModifiableSimpleValueSet();

i checked for the nullity of the values in vhm1. if values exists i cleared them using vhm1.clear() method. And my issue of page cache is also solved.

Thanks in advance poojitha...
