Error Rendering View[/index.xhtml] java.lang.NumberFormatException: For input string: ""

Translated:

I have seen a lot of questions like I have, but those were no good: the biggest difference is my string is empty, and I can't find which component lacks data.

Context: I'm using the tags <h:form> and <p:commandbutton> to test a simple function which prints something with System.out.println().

The error happens when I click the commandbutton inside one of the rowexpansions. The system.out.print doesn't show up in the tomcat prompt. I've searched everywhere for that empty string.

What is happening? How can I debug this? How can I fix it?

EDIT :

Based on some of the answer given, I tried altering the components: The basic structure is like this: Based on your answer, I've tryed to make a single <h:form> in the following simplified structure:

<h:form>
      <p:datatable>
          <p:rowExpansion>
                SOME INPUTS HERE
                <p:commandButton action="PRINTSOMETHING()">
            </p:rowExpansion>
       <p:dataTable>
</h:form>

It still hasn't worked, the exception is the same. I think I unnested forms now, am I correct?

EDIT NUMBER 2

I've added the LifeCycleListener Class, the stack trace changed. it changed the Error Stack, it seems it does run the bean method. The error is triggered after the bean method runs. I've editted the error stack.

After many tries, i found some fundamental problem. My managed bean, "BeanGestao" was configured in faces-config.xml as:

RequestScoped.

So the @ViewScoped annotation was being ignored. That's why my managed bean was being restarted a lot.

I guess the configuration in faces-config.xml is stronger than the annotation.

Thanks for the help! It wasn't easy to help me and my confusing problem.

The exception is not related to your input fields nor domain model or validation, it happens in PrimeFaces RowExpandFeature:

public void encode(FacesContext context, DataTableRenderer renderer, DataTable table) throws IOException {
    Map<String, String> params = context.getExternalContext().getRequestParameterMap();
    int expandedRowIndex = Integer.parseInt(params.get(table.getClientId(context) + "_expandedRowIndex"));

The top of your exception stack trace directly points you there:

java.lang.NumberFormatException: For input string: ""
    at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
    at java.lang.Integer.parseInt(Integer.java:592)
    at java.lang.Integer.parseInt(Integer.java:615)
    at org.primefaces.component.datatable.feature.RowExpandFeature.encode(RowExpandFeature.java:48)

The component is unable to determine their own clientId correctly and thus does not find the _expandedRowIndex POST value. The most likely root cause is you are nesting forms.
