QUESTION
I'm trying to re-render a component using useEffect and passing dependencies, but it isn't working. I'm quite new to react hooks so I think I might not be passing the correct dependency. I'm fetching some info and updating the state, however, when I passed the dependencies the re-render cycle does not happen.
Here is the code:
...ANSWER
Answered 2021-Apr-29 at 20:34You probably only want the HTTP call to be made once (when the component mounts), so use []
as the dependency list. The HTTP call doesn't depend on any other props or state, so this most likely what you want.
If you want it to run more often than that, then you'll need to decide what data changes that requires you to make the HTTP call again, and add that to the dependency list instead of numberOfAnswers
or setNumberOfAnswers
.
The problem is that your effect lists numberOfAnswers
as a dependency, and it also updates numberOfAnswers
when it runs. So, this is likely what's happening:
- The component mounts.
numberOfAnswers
is undefined by default. - The effect runs for the first time.
- The HTTP request returns, say with 10 answers. It calls
setNumberOfAnswers(10)
- The component rerenders with
numberOfAnswers=10
- The effect runs again, because
numberOfAnswers
changed. - The HTTP request returns, probably with the same 10 answers. It calls
setNumberOfAnswers(10)
- The component does not rerender again because the value hasn't changed.
QUESTION
I'm trying to submit a form that sends a http request onSubmit, but I'm getting undefined when setting the state on the values. I'm not sure why the values are not being passed upon click and being set with the set...() function.
Below is the code of that component. Upon first submit action I get an error because the "surveyUserAnswers" are undefined, but in the next submissions it works. Not sure why? Could someone advise.
I'm very new to typescript and react hooks, so excuse my code! thanks
...ANSWER
Answered 2021-Apr-29 at 07:45Setting the state is an async action, and the updated state would only be available at the next render.
In your case, the default state is undefined
, and this is what you send at the 1st submit. The state is now updated, and when you submit again, you send the previous answer, and so on...
To solve this, prepare a const (newAnswer
), and set it to the state, and use it in the api call.
Note: in your case, you're not using the surveyUserAnswers
at all, so you can remove this state entirely.

QUESTION
I have created code with iText 7 that is able to digitally sign a given PDF with a X509 certificate that uses an ECDSA key pair. When I open this signed PDF in Acrobat Reader DC, it correctly reads it, and verifies it to be valid (meaing doc is unmodified since signing, etc etc).
However, when I try to validate this same document with iText 7, the integrity and authenticity check returns false.
Here is a sample code:
...ANSWER
Answered 2021-Apr-25 at 16:00There is an issue in your ECDSA signatures which is only ignored by Adobe Acrobat but not by iText 7.
There are two major formats to encode an ECDSA signature value:
