    I am working on Telerik Reports which are migrated from Silverlight. 
    I am now using HTML 5 Report Viewer. 
    There is one report that gives this error : "Internal Server Error. Child doesn't implement ITableCell."
    The report is compiled and generated correctly in the HTML Preview Pane in the Visual Studio. 

    Also, what actually happens is that the sometimes (as I have noticed) the report data does come and populates and then vanishes in a blink giving this Error. 
    I have attached a screen shot of the error view. 

    I am expecting some quick response.
    Thanks.

    Hi Pooja,

    This exception should appear only when a table structure cannot be correctly traversed in order to generate the accessibility attributes of its cell. It is possible to indicate a bug in our implementation, so we would like to ask you to send us the report definition so we can investigate it on our side.

    In case you do not need the accessibility features of the viewer, please set the viewer's enableAccessibility property to false. This way the processing engine will not traverse the elements, hence the error will not appear.
