Try using Alfresco Javascript instead:

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
   <script>
      <variable name="od_tempCnt" access="write"/>
     <expression>
          od_tempCnt = bpm_package.children.length;
      </expression>
      </script>
</action>

<decision name="decision1">
        <description>
            Note. I found often that the default transition "no" has to be first in this decision node otherwise the condition will
            always evaluate to true.
        </description>
        <transition to="ProveraKvalitetaUpitnika" name="ok"></transition>
        <transition to="Uploaduj upitnik" name="missingdoc">
            <condition>#{bpm_package.children.length<=od_tempCnt}</condition>
        </transition>
    </decision>

Sorry, my fault the decision node is not a task node.

You have to setup another variable when users leave the task (where they must add doc) that contains the new count and then use in decision:

<variable name="bpm_package" access="read" />
               <expression>
               new_timecapsule= bpm_package.children.length;
             </expression>

<decision name="decision1">
      <transition to="ProveraKvalitetaUpitnika">
         <condition>#{new_timecapsule>=od_timecapsule}</condition>
      </transition>
      <transition to="Uploaduj upitnik" name="Fali dokument">
      </transition>
   </decision>

Hi,

Can you post the solution to the problem?

Is it to create a node-end task and setting the variable there?

Thanks

well, it is soloved, but dropped because this lead to thousands lines of code, so not very good solution my friend. let me tell you in advance.
And it was not working when you split workflow on N distinct users. So just drop it , or make changes to the workflow bean who renders workflow actions and limit there upload with some settings .
