Javascript error: Object doesn't support this property or method

[fuhrj]

Using Build 10.20 and Internet Explorer 8.

When a report is loaded into the Webviewer and the report contains form parameters, I get this error:

Line 574:
Error: Object doesn't support this property or method

If I debug the message, IE is complaining about this line from the Javascript function below:

webViewer = document.getElementById(webViewerId);


Full javascript:

function HideLoadMessage(webViewerId)
{
reportFrame = document.getElementById("webReportFrame_" + webViewerId);
loadMessage = document.getElementById("webLoadMessage_" + webViewerId);
reportTable = reportFrame.contentWindow.document.getElementById("webReportTable_" + webViewerId);
scrollFrame = reportFrame.contentWindow.document.getElementById("webScrollFrame_" + webViewerId);

heightDelta = 40;
if (scrollFrame != null) heightDelta = 0;
if (reportTable != null)
{
reportFrame.width = reportTable.offsetWidth;
reportFrame.height = reportTable.offsetHeight - heightDelta;
}
loadMessage.style.visibility = "hidden";

// debugger;
if (scrollFrame == null)
{
webViewer = document.getElementById(webViewerId);
webViewer.style.width = reportTable.offsetWidth + "px";
webViewer.style.height = reportTable.offsetHeight + "px";
}
}

The report runs, but I need to fix the Javascript error from showing every time the report is loaded into the Webviewer.

I know this is a bump to an old topic, but it is still relevant today so my apologies. This topic just happens to contain the keywords that most people are looking for when trying to figure out what is happening.

This error occurs as a result of the viewer using the same page in a manner similar to an ashx page to load images for the viewer.

The parameters your page is looking for do not exist on the version of the page that is loaded when the image lookup is performed.

To give you an example...

You load a url like this:

myReportViewerPage.aspx?reportID=6&something=73

The Viewer loads the first pass using your parameters. Then it does another *partial* load for each image like this:

myReportViewerPage.aspx (can't remember if there is a parameter tacked on here, but the variables above are missing)

The error occurs when your page's logic tries to process the viewer setup but can't find the parameters it needs to do so. I resolved the issue on my page by checking for one of my parameters. If the parameter doesn't exist, then I know the Viewer is loading images, and I don't perform any of my logic.

Hope that helps
