Someone please help me find the solution for it..........
Your jSP has an compilation issue...Check whether your JSP fine
There's something wrong with a hidden tag in your JSP. Check the Struts 2 documentation on hidden tags (http://struts.apache.org/2.2.3/docs/hidden.html) to make sure everything's compliant. Try removing it temporarily, and if that fixes the problem start changing bits and pieces of it until you know what the problem is. Also, are you using Eclipse? If not you should, because it will make it a lot easier to figure out where things have gone wrong with your tags.

I made an error when using a ViewHelper with an unsupported argument and my Fluid Partial wasn't rendered at all.
How can I debug / track down problems like these? Usually I would expect an exception to be thrown. I enabled debug preset and there is nothing in the sys_log, no error message is displayed.
Is there some setting I can use to cause error messages to be created or more information to get logged?
Reproduce
Use Fluid ViewHelper with unsupported argument (here, name is not a supported argument):
<f:uri.external name="something" uri="https://typo3.org">f.uri.external</f:uri.external>
Result
The Fluid Partial is not displayed at all.
most of the time I'm using to check do I even get wanted values before:
<f:debug>{_all}</f:debug>
or
<f:debug>{variable}</f:debug>
I've been asked to look at C# code that's returning the following error:
Unable to cast object of type
'iTextSharp.text.html.simpleparser.IncCell' to type 'iTextSharp.text.Rectangle'.
at iTextSharp.text.pdf.PdfDocument.Add(IElement element)
at iTextSharp.text.Document.Add(IElement element)
It looks like they're using iTextSharp v5.0.2 and have not yet moved from HtmlWorker to XmlWorker.
Questions:
What is IncCell? I see it in the source docs but can't find any info about what it is - I'm assuming it's just for internal use.
Is this related to a cell in a table? A need for a Div or Paragraph within a cell?
What can they do to diagnose issues like this down to the HTML source that caused the error? I suspect this is an issue with not conforming to XHTML, but I can't verify that without knowing exactly what IElement that code was working on when it choked. It could be due to bad styling too, I have no idea at this time. Is there any kind of detail logging that will tell us what element is being processed at any given time? Should I just get them to load source and trace through it?
Is it probable that this will be fixed with an update to the latest version (currently 5.5.9), and a re-fit of XmlWorker?
Other recommendations?
Thanks!
Site works fine. Suddenly it will through an error. When clicking "flush system cahce" the error will go away for a some time. Anything from minuttes to severaæ hours.
Core: Exception handler (WEB): Uncaught TYPO3 Exception: #1247602160:
Unknown column 'tx_my_domain_model_formular.rel_formular' in 'where
clause' |
TYPO3\CMS\Extbase\Persistence\Generic\Storage\Exception\SqlErrorException
thrown in file
/webserver/typo3/src/6.2.15/typo3/sysext/extbase/Classes/Persistence/Generic/Storage/Typo3DbBackend.php
in line 862.
It is correct that the columns does not exist. But how to preceed in finding the error after this? Where is the sql generated that causes the site to crash?
UPDATE
A check "myParentObj->getChildObj instanceof myChildObjClass" used to work just fine. After changing myParent model to lazy load the ChildObj, then the class of childObj changed from childObjClass to a lazyLoadClass... I am not sure but I guess that is in turns somewhere somehow caused the core error seen in the log.
How to investigate further I simply cannot work out. Eg. store all DB calls in a file og DB to analyze after the error occours.
First
Please take time to write a good question. For a good question you'll get a good answer. It doesn't have to be perfect (not everyone is a native english speaker) but please reread your question.
Answer
If all fields are defined correctly, just run a DB compare from within the installtool.
If not, you need to define the DB-fields in your extension correctly.
Is this your own extension? When doing the query that triggers the error you could call execute(true) to generate the actual SQL statement and debug from there.
I use IntelliJ IDEA 15.0.4 to develop a Java Play! 2.4.4 application. Since a few months (I think it was because of an IntelliJ update, but not 100% sure) the following problem occurs:
Whenever I call a reverse route from a controller that takes a String as a parameter, the parameter is displayed as an error with the following message:
methodName (string) in ReverseMyController cannot be applied to (java.lang.String)
Here's a code example:
public Result myAction(String myId) {
// Do something...
// Redirect back to referrer
flash("success", "Action was a success");
if(!myId.isEmpty()) return redirect(controllers.routes.MyController.showItem(myId));
return redirect(controllers.routes.MyController.itemList(1));
}
In this example, the parameter myId passed to the method showItem would be error highlighted, like this.
I already tried fiddling with the Project Structure settings and searched Google, but to no avail. I hope somebody is able to help me with this, my OCD-self would really appreciate having a code base with no error hints again ;)
Accepted answer does not solve the problem that is why I am answering this old question.
I had the same problem with Play 2.5.4 and InteliJ 2016.1.3
I removed the type (String) from route declaration in routes file and InteliJ stopped highlighting it as error.
Change following:
GET /path/:string_arg controllers.MyController.myMethod(string_arg: String)
To
GET /path/:string_arg controllers.MyController.myMethod(string_arg)
and it works fine.
Yes, I meet the same issue as what you said. I think it is a bug of the IDEA 15.0.4, Have you tried to change to the older version before 15.0.4?
Please let me know what i am doing wrong here:
I need to add dynamic content to my htmy table using GWT.
I am using setInnerHTML method for this
Element tableElement=(Element) Document.get().getElementById("htmltable");
tableElement.setInnerHTML("<tr><td>1</td><td>2000</td><td>2</td><td>3000</td></tr>");
But i am getting this error
com.google.gwt.core.client.JavaScriptException: (Error): Unknown runtime error
number: -2146827688
description: Unknown runtime error
Please let me know what i am doing wrong here.
this can be due to multiple reasons.
If this is happening on IE only this post covers it: Debugging IE8 Javascript Replace innerHTML Runtime Error
In Ie you can not set the inner html of a table element.
From GWT CellTableImplementation for IE:
IE doesn't support innerHTML on tbody, nor does it support removing or
replacing a tbody. The only solution is to remove and replace the rows
themselves.
