To simplify all of this, you don't need to Environment.SpecialFolder variable at all, nor do you need to pass it as a parameter.

The reason that an exception was thrown is because you tried to parse a string into an Environment.SpecialFolder variable enum, when the string could not be parsed into one.

You can look here to see the list of enums included. I would wager that the specific path you selected matches none of those.

Here's what your code is currently doing:

1. Selecting a path
2. Trying to parse that path to get an enum for a special folder
3. Trying to get the string associated with that Environment.SpecialFolder variable (so if you had actually been able to parse it, you would've ended up with just what you started with)
4. Combining that string with the name you wanted to give the PDF.

You can simplify all of this by omitting steps 2 and 3, which cause the error.

ArrowForm is reloading the page when the submit button is pressed. You should prevent default form action on the onSubmit event object.

Seems it works, it opens in the background, so it is not recognized. Moreover, such Windows forms do not appear in the task bar, therefore, you need to minimize/close all your running applications to see the form. Watchout when working with multiple screens...

There are lot of issues in your code, I have tried to fix many of these. Please let me know if still not working.

The Spring Data JDBC library itself does not contain a Firebird dialect out of the box, so you need to provide one yourself. How to do this is documented in Annotation-based Configuration of the Spring Data JDBC documentation:

Dialects are resolved by JdbcDialectResolver from JdbcOperations, typically by inspecting Connection. You can let Spring auto-discover your Dialect by registering a class that implements org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider through META-INF/spring.factories. DialectResolver discovers dialect provider implementations from the class path using Spring’s SpringFactoriesLoader.

To be able to use Firebird, you will need to define three things:

1. A dialect
2. A dialect resolver
3. A config file for Spring to locate the dialect resolver

The dialect can be something like (note, this dialect assumes Firebird 3 or higher):

The key is to generate series of business days and number them with row_number():

So I managed to resolve this by implementing the following code:

The IW_PR_Schrittnummer is linked to input I/O using AT %ID716 command. So it gets its value from I/O memory. That basically means that "take this value from input memory at address 716 and the size is D (double word, 32 bits).

I'm not sure how you can check what is in that address when it's defined with direct addressing like this. Hopefully someone else knows a good tip for this!

That logic from your 1st image works as you said. So AutoFinde will be TRUE, if Auto, AutoAktiv, IstFrei are all TRUE and the input IW_PR_Schrittnummer is 0. Otherwise the AutoFinde will always be FALSE.

You are getting the following error:

Can't convert an object of type java.lang.String to type com.example.positivethinkers.Members

Because you are looping through the dataSnapshot object which contains String properties and not Members objects. When you add a ChildEventListener on the Members node, onChildAdded() method is called for each and every child that exists within that node. So there is no need for an iteration. To solve this, simply remove that for loop like in the following lines of code:
