Modifying data type of binary attribute

[Former Member]

Hello

I am not able to modify the context attribute using

IWDModifiableBinaryType binaryType =

(IWDModifiableBinaryType) attInfo.getModifiableSimpleType();

binaryType.setMimeType(WDWebResourceType.JPG_IMAGE);//Example *.jpg

beccause the data is mapped from the component controller .

Geeting the folllowing exception when I rin the program.

com.sap.tc.webdynpro.progmodel.context.ContextException: AttributeInfo(IPrivateXYView.IXYElement.PIC_DB):

must not modify the datatype of a mapped attribute

how to resolve this issue.

thanks

Hi,

Please incrase Time duration of the project in Webdynpro. Appication>Property>Application Property-->Add predefined variable with some delay time.

Then redeploy it will work fine.

Kind Regards,
