I have the file below. Using jtc how to I replace all occurrences of "value": 1234.56
with "value": {"$numberDecimal":"1234.56"}
; that is, wrap the numbers. This is for mongoimport

I am trying to get some values from an online XML document, but I cannot find the right xpath to navigate to those values. I want to import these values into a Google Spreadsheet document, which requires me to get the exact xpath.
The website is this one, and I am trying to get the information for "WillPay" information from MeetingInfo Venue=S1, Races RaceNo=1, Pools PoolInfo Pool=WIN, in OddsInfo.
For now, the value of "Number=1" should be 3350 (or something close to this, it changes quite often), and I would like to load all of these values onto the google spreadsheet document.
What I've tried is locating the xpath of all of it, and tried to my best attempt to get

QUESTION
When trying to simulate input using AssertJ's pressAndReleaseKeys() for unit testing a JComboBox in a Java Swing program, I am not seeing the expected behavior. The program will most often hang on the pressAndReleaseKeys line and then fail, or occasionally will delete all the text currently in the JComboBox being tested, causing later assertions to fail (i.e. requireSelection()). The stack trace I receive for the provided example program (see below) when it hangs is as follows:
Focus change to javax.swing.JComboBox[name='combob', selectedItem='Bean', contents=["Pork", "Beans", "Rice"], editable=true, enabled=true, visible=true, showing=true] failed focus owner: javax.swing.plaf.metal.MetalComboBoxEditor$1(javax.swing.JTextField)[name=null, text='Bean', enabled=true, visible=true, showing=true]

I have been using FEST and am hoping to migrate my tests to AssertJ since it is being actively maintained, whereas FEST hasn't been updated for years. I used Joel Costigliola's migration from Fest to AssertJ guide, but am having trouble when simulating keyboard input by using pressAndReleaseKeys(). I am able to simulate input when using a JTextComponentFixture i.e.

Answered 2019-Mar-25 at 15:14This is not an answer to the question, but a workaround that allows the desired behavior. This issue can be mitigated by invoking robot() for the comboBox().
Instead of
window.comboBox().pressAndReleaseKeys(KeyEvent.VK_S);
try doing
window.comboBox().robot().pressAndReleaseKeys(KeyEvent.VK_S);
QUESTION
I've encountered a problem today that I've so far not had any luck tracking down. I created a new migration file (via 'rails g migrate ...'). After creating the file, when I run rails db:migrate or rails db:migrate:status, the result is that rails appears to be infinitely starting itself - i.e., forking. If I remove the new migration file, this no longer happens - e.g., rails db:migrate:status results in the status report displaying and completing. To verify that rails was forking when I ran the migration, I ran, in a separate terminal:
...ANSWER
Answered 2019-Feb-26 at 21:00I'm assuming you haven't done something sensible like using git or something to track your versioning (if so, just roll back everything).
Just in case I'd stop (or kill
if necessary) any spring
that's running.
Re troubleshooting this issue, I'd recommend creating a new app and copying over your migrations and running them in the new app, to confirm it's not your migrations. Then just copy over your app
and other changes. Then install and use git
or something like it to make problems like this trivial to resolve in future :)

I just ran into an error when I was using the Newtonsoft.Json SerializeObject
method. It has been asked before here, but there was no answer from the people working with Newtonsoft as to why this happens.
Basically, when calling SerializeObject

ANSWER
Answered 2018-Dec-03 at 17:35Why will JsonConvert.SerializeObject call the
object.Equals
method?
Because when you use JsonConvert.SerializeObject
, there is a method CheckForCircularReference which is called to check whether a property re-references your own object, leading to an infinite loop.
