We are finding this behaviour on NiFi 1.8.0.
As you can see by the pictures, the flowfiles have the attribute set (both by visual inspection and by being passed through a RouteByAttributes that checks ${database.name:isEmpty():not()}
We also tried removing the attribute and adding it explicitly again, but the behaviour still holds.
Please note that we are using the DBCPConnectionPoolLookup+database.name mechanism successfully in other parts of the diagram.
Any ideas on how to troubleshoot or what to look for?
Thanks
Since my app is online for to be tested by customer, I often meet this problem and I have to click several times on "Tiers" menu to hope it will disappear and give hand.
Here is a snapshot of the trouble :
WHen I use my app on local server (wampserver) I never meet this trouble.
I have several grids in my app and none displays this message online.
Firebug says "jquery.jqgrid.min.js" has error in line 344 (?). Used version is 4.13.5-pre dated 2016-08-27 and hosted server runs with php 5.6.8
Does somebody already met this type of trouble ?
If somebody can take some time to help me, I can give by email login and pass to test app online.
Many thanks for your kind help.
Cheers

Thank you for reporting the issue. It would be helpful if you report the error using jquery.jqgrid.src.js instead of jquery.jqgrid.min.js, but I suppose that the only place in the code, which could produce the error is the piece of code with if ($input[0].tagName.toUpperCase() === "SELECT" && $input[0].multiple) {... (see here).
I posted the fix just now, which should eliminate the error. It includes the additional test if ($input.length > 0) {...} (see the line). I would still recommend you to examine the name and index values in colModel of your grids. It seems that your current code uses the filter with names or index, which is not from colModel or which uses some special characters. It's the only reason of the error, which one can see in console of your picture.
I understand that there is definitely something wrong with my report (e.g. columns missmatcch) and I need to correct it but what I see is the WCF error message that hides actual problem and exactly this hiding irritates me much more than original problem: columns missmatch.
I guess we need to adjust the WCF 'buffer size' and we will get original problem message. But where is the config file?
Text search of "system.serviceModel" in the C:\Program Files (x86)\Microsoft Visual Studio 10.0 doesn't bring good idea...
P.S. Since this is just preview of report I do not think that it is SSRS configuration problem. Problem localised somewhere in DevStudio process or int the DevStudio's internal web server process ...
P.P.S Please help me too improve the question. I see that responders doesn't understand what kind of help I need.
I have encountered multiple "flavors" of this bug in SSRS Preview. It seems the renderer for Preview mode is quite fragile.
There is a simple way to solve this. Ignore the error and attempt to upload the RDL file to your reporting server. The uploader will happily tell you exactly what is wrong with your file - it will tell you exactly what field has a problem and what that problem is. If there are multiple errors, you will get told each and every field and the error associated with each one.
I can create this bogus XML buffer error with any of the following:
Add a new Tablix, start to connect it to a dataset, then cancel out.
Copy/paste some text into a textbox from a MS Word document where one or more lines have a negative right indent (right column end is outside page margin).
Connect a dataset with a varchar(8000) returned value.
Please Check if any of your report items are referencing fields that are not in existing dataset scope.
This indeed worked for me.

I have seen this error when adding a new field to an existing dataset by clicking "Refresh Fields".
The dataset source was a stored procedure. The result was only a few of original fields showed up in the dataset field list and not the new field. If I tried to preview the report I get XML buffer error.
Workaround was to not refresh fields but hit add new field and type the new field name into the dataset properties field last.
Worked fine after that.
I got this error again today.
I had created a table to hold data to replace two slow queries. I changed some names to clean up the process.
I think the error actually means that there are so many problems with my report that the buffer holding the various error messages isn't large enough which leads to the error message.
The size necessary to buffer the XML content exceeded the buffer quota
Of course this should be an easy fix but Microsoft has said that they will not fix it.

EDIT: I've updated my answer based on having fixed the issue.
I'm currently experiencing this problem after having changed multiple stored procedures and updating the dataset names in the SSRS report.
And when I try to run the preview I get the exact same error.
As it turns out, after investigating the issue, the problem was that I had changed the name property of my datasets.
There several places in my report where formulas or expressions use the old name properties of the datasets I renamed. After reverting the dataset names back, I managed to get the real errors like missing fields etc. atcual errors came back after I set my dataset name properties back to what they were.
I only changed the name property back to what it was, the stored procedure names were correctly referring to my renamed stored procedures.
I had this problem when after copying and pasting a tablix, it changed CDbl in a formula to Microsoft.ReportingServices.RdlObjectModel.ExpressionParser.VBFunctions.CDbl. I opened up the XML and removed all instances of "Microsoft.ReportingServices.RdlObjectModel.ExpressionParser.VBFunctions." and the report then worked.
For a working report, when I tried to add a column it gave me this error. I edited the .rdl file using notepad++. After SSRS prompt to reload the change from disk, it worked without issues.
I got this error after copying my Custom Code to Visual Studio for hightlighting the code for better readability. Well, Visual Studio added class definitions to the beginning and end of the file. After editing code, I pasted it back to report Custom Code, then got this error. Fix was just to remove class definitions (Public Class Class1 and End Class) from Custom Code. So, check your Custom Code also (if any).
I got this error after adding some new parameters to an existing report.
For some reason when I created the parameters first then modified the Dataset to use the new parameters I got the error, but when I modified the Dataset first then added the parameters second and I did not get the error.
This seemed like very strange behavior to me so I tested it by restoring the report from repository and repeating the process three times with each method, and had identical behavior every time.
I am also facing this problem. I solve this Find and replace
Microsoft.VisualBasic.Interaction.iif ==> iif
Microsoft.ReportingServices.RdlObjectModel.ExpressionParser.VBFunctions.cdbl
==> cdbl
I hope this may helps someone. Thanks
Possible root causes
Parameter name is incorrect(case/order)
Accessing non-existing property.
and many more...
Solution: To get the exact error message are
Deploy SSRS report and find the error : Suggested by "Kim Crosser" already
Remove the section(SSRS/Report content) temporarily you feel is error free to free space in buffer so that you can get actual error message. Later add sections back to the page(removed earlier).
I had the same error message and it was totally caused by my doing. It's a bit embarrassing, but if it helps someone out then great! I had accidentally copied my dataset query that included a small sub select statement within it, which I was using to check parameter/variable values.
Another solution is to open the .rdl file in Report Builder 3.0 (as opposed to Visual Studio) and try to preview it. I found this gave me the details of the error, although if more than one error is present it only shows the first.
I previously binded a TextBox to
Fields!FieldName
and fixed it with
Fields!FieldName.Value
With that said, and with the other answers posted as well, this error happens in different flavors. My issue was fixed after I had the field property "Value" included.
I have an xtext validation precedure which traverses the elements of the document and might find errors on elements in other files as the one being checked. However, when committing the error it is not marked in the other file, but in the current file at the position of the erroneous element in its file.
How can I assign an error to an other file?
I guess that there is some kind of relationship between the elements in your first document and the element of the other ones. Are the latter imported ? Do your elements cross-reference elements present in other documents ?
In either cases, you should normally be able to access the element at fault in your other document through a reference or a proxy. And once you have this EObject, you can get a link to its resource, on which you should be able to add errors and warnings.
Does it answer your question ?

I'm currently trying to get an rdlc report to work, and it works fine except when I pass an empty dataset to it (the dataset is determined dynamically at runtime -- ugly, but this is the code I was passed and I'm not quite experienced enough to really feel confident about wiping it and rewriting it). When I pass it an empty DataSet, it fails with an "Object reference not set to an instance of an object." The strange thing is, I have another report that gets passed a similar DataSet, but it doesn't fail. I'm not quite sure why one report with an empty DataSet is failing, but the other is not.
Any help is much appreciated!
Figured it out. As it turns out there was a stray parameter that wasn't getting set... rebuilding the report from the ground up did the trick.
