[Former Member]

Hi

When I am tring to display EVS text value in attached input field I am getting following error.

I am dynamically fetching the evs values from model and in the calculated field I am fetching the text value of selected key . but it is not working ....

error is :

java.lang.StackOverflowError: JVMXE018: Insufficient Java stack size .

Any idea.

Value Node Name :Buffer

calculated Attribute name: MyAttibute

This explains why you get a recursion. You (implicitly) call the getter of the calculated attribute inside the method itself.

Kousik,

As stated earlier by me please visit the third link. In case you are having problems giving you the direct link as below:-

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webas/webdynpro/ye... another evs valuehelp - showing display texts for keys.article

The article contains the exact thing you want to implement. So check the "Showing Display Texts Inside an EVS Input Field (EVS++)" section in above link.

But if I attach the InputField with the new TEXT calulated attribute then how EVS will be available with my input field?

That's another question. You talked about displaying the text in an input field.

What you could do: place a TextView after the input field that always displays the text corresponding to the current key.

Please let me know how to solve the issue...

Set the attribute storing the key to "not calculated", add a new calculated attributed "Text" and put the code in the getter for the "Text" attribute.

String attributeName = IMYView.IViewBufferElement.MyAttibute;

IWDAttributeInfo attributeInfo = element.node().getNodeInfo().getAttribute(attributeName);

ISimpleType simpleType = attributeInfo.getSimpleType();

ISimpleValueSet valueset = simpleType.getSVServices().getValues();

Object key = element.getAttributeValue(attributeName);

try {

simpleType.checkValid(key);

return valueset.getText(key);

} catch (DdCheckException e) {

return "";

}

What is the name of the calculated attribute?

The stpes which I am following is ....

1. I have a value node which I am popuating dynamically at runtime with the key,value pare getting from model.

2. now at the calculated getter method I am writting code for getting the text of the key.

Can you post the complete code for the calculated field?

Armin

[Former Member]

Yes I wrote the same code .

[chintan_virani]

Kousik,

The third link gives the code snippet to implement the EVS.

Is the following code in place after the code statement u wrote?:-

try {

simpleType.checkValid(key);

return valueset.getText(key);

} catch (DdCheckException e) {

return "";

There is no problem in EVS . The error is coming at the time of displaying text from key and to be more specific the error is coming in the following line at calculated get method when I am tring to retreive the text of the key

Object key = element.getAttributeValue(attributeName);
