UserInputPanel does not changes the binding's dynamicvariable

Can you attach a minimalist install.xml and userInputSpec.xml that can be used to reproduce the behaviour?
It will make it easier to diagnose and develop a test case.

I'm experiencing(with beta11 build locally) the same thing only when I'm accessing dynamic variable(DV) "DV_JBOSS_MASTER_ADDRESS" in my java class called by process panel, but the DV gets correctly replaced with the modified value when called <parsable/> node over the file on which I've putted the DV(in my case a BAT file).

My snippet code:
install.xml
<installation version="1.0">
...
<variables>
...
<variable name="V_DEFAULT_JBOSS_MASTER_ADDRESS" value="localhost" />
...
</variables>
<dynamicvariables>
...
<variable name="DV_JBOSS_MASTER_ADDRESS" value="$

" condition="C_NODE" />
<variable name="DV_JBOSS_MASTER_ADDRESS" value="$

" />
</field>
</panel>
...
</userInput>

I can't reproduce this locally with the latest 5.0.0-beta11-SNAPSHOT.
One thing to be aware of is that dynamic variables are only updated when navigating to the next or previous panel.

I can't reproduce this problem here with the current 5.0.0-beta11-SNAPSHOT, neither.

As Tim already wrote, as long as the given pabnel (in your case "P_userinput_master") is active, the variable can't be resolved, because it can't be assigned in you usecase. Therefore, in that moment the value of DV_JBOSS_MASTER_ADDRESS is $

(unresolved) according to the specification of resolving variables in IzPack.

As soon as you change to the next panel, VI_MASTER_ADDRESS gets assigned and DV_JBOSS_MASTER_ADDRESS receives the resolved value.

This does definitely work with the current implementation.

Hint: Please launch the installer with -DTRACE=true and watch the variable and condition value transitions along with switching between the panels.

I had to downgrade izpack version to the ones mentioned below, being able to fulfill my task of building the installer for my project.

<izpack.maven-plugin.version>1.0-alpha-5</izpack.maven-plugin.version>
<izpack.standalone-compiler.version>4.3.2</izpack.standalone-compiler.version>

So, I'm not able at the moment to change all my configuration and retest with snapshot beta 11.

As Dan mentioned at the beginning, the value for input panel doesn't get updated when adding a validator or a process panel get executed, after the value is filled and next button is pressed(debug in Validator/ProcessExecutor and see that the initial value is set to the dynamic variable).
Define a Validator for the input panel and check if the dynamic variable(initially set to a default value) gets updated with the one from input, which I'm expected to be updated accordingly with the one filled in input, in order to be able do my validation. Am I approaching it wrong?
