Define a calculated attribute and bind the UI element property, e.g. Image.source, to this attribute.

In the generated getter, return the name of the image file depending on the condition value.

Hi Armin,

Thanks for your response,

I have done what u said in previous post.

That calculated Attribute getter method retunrs only the string value.

Here my problem is I want to retrive the Images from src-mimes-componets-one.jpg

In My calculated getter method only I am getting this as a string.

but I want to map this as a Image in UI Interactiveform but that UI Elemenets needs to display as Image or Static image for we need to pass the URL.

Give any otheralternative solutions.

Thanks

If you need the complete URL, you can use the WDURLGenerator API.

Can you post the stacktrace?

A possible cause may be that you call the calculated attribute get<Attribute>() method inside itself and get a recursion.

Hi

public java.lang.String Z_Ff_Ar_Invoice_Copy_InputImageUrl(IPrivateInvoiceAppView.IZ_Ff_Ar_Invoice_Copy_InputElement element)

{

//@@begin getZ_Ff_Ar_Invoice_Copy_InputImageUrl(IPrivateInvoiceAppView.IZ_Ff_Ar_Invoice_Copy_InputElement)

String path ="";

String title = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("title");

if(title.equalsIgnoreCase("ONE"))

{

try {

path =

WDURLGenerator.getAbsoluteWebResourceURL(wdComponentAPI.getDeployableObjectPart(),"ONE.jpg");

} catch (WDURLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return path;

}

else

{

try {

path =WDURLGenerator.getAbsoluteWebResourceURL(wdComponentAPI.getDeployableObjectPart(),"LII.bmp");

} catch (WDURLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return path;

}

This is my gettter method.

In context rootnode mapped to Interactive element contain the my attribute imageUrl that have created as calculate attribute.

This imageUrl Attribute only getting the images that need to be mapped into Interactiveform UI element.

And getting the path variable to setted to imageUrl then it shows error like this.

Root Cause

The initial exception that caused the request to fail, was:

java.lang.StackOverflowError .

This is my problem.

Please suggest me.

Thanks
