Hi,

i'm not familiar with workflows in jbpm (try activiti, jbpm will no longer be maintained), but i think i can help you.

Your models are good, i may change the web-client-config. Rather show properties of your object ct:


<config evaluator="node-type" condition="sgn:Pomysl">
    <property-sheet>
        <show-property name="ct:nazwa" display-label="Nazwa"  />
        <show-property name="ct:opisPomyslu" display-label="Opis pomysłu" />
        <show-property name="ct:kluczoweProblemy" display-label="Kluczowe problemy" />
(…)‍‍‍‍‍‍‍

And for your process-definition, i should use variables assigned directly to tasks, such as:


<event type="node-enter">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
               task.setVariable('ct_nazwa', bpm_package.children[0].properties["sgn:Nazwa"]);
         </script>
         </action>
      </event>      
      <event type="node-leave">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
                bpm_package.children[0].properties["sgn:Nazwa"] =  task.getVariable('ct_nazwa');
         </script>
(…)‍‍‍‍‍‍‍‍‍‍‍‍‍‍

thanks for Your answer, You've helped me to go few steps further
Your exact snippet didn't work, but it had inspired me to search in a different way and helped me to find out that:
when I set web-client-config just as You set, and when I try this:

<event type="node-enter">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
              executionContext.getContextInstance().setVariable('ct_nazwa', bpm_package.children[0].properties["sgn:Nazwa"]);
         </script>
         </action>
      </event>      
      <event type="node-leave">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
                bpm_package.children[0].properties["sgn:Nazwa"] =   executionContext.getContextInstance().getVariable('ct_nazwa');
         </script>
(…)‍‍‍‍‍‍‍‍‍‍‍‍‍

it almost works, I mean: I can get a value from a field from content, then I can display it in a UI, then I can change it on UI and save it to bpm_package.children[0].properties["sgn:Nazwa"] during first step and finally I can display that value in second step. There is only one thing i do not understand: When i navigate on my task (the second step) UI to Resources->Actions->Edit Content Properties I still see the old value. So it seems that I have already changed only on some kind of a copy of a metadata. How to make update on original content metadata ?

Oups, sorry! :lol:
Like you, i forgot the usual magic line:

bpm_package.children[0].save();‍

Without it, document is not updated…
