<div class="jive-rendered-content"><p>Hi !</p><p>I had localized this problem. The class org.jbpm.pvm.internal.script.EnvironmentBindings doesn`t store locale variables from script:</p><p><em><strong>public Object put(String key, Object value) {<br/>    return null;<br/>}</strong></em></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Groovy engine ignores it and stores local variables in its own storage.</p><p>Jython engine obeys the limitations of Bindings, so it can`t store local variables if Bindings doesn`t allow it!!!!!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If is it desireable behaviour ?</p><p>Possible solution is adding local storage to EnvironmentBindings and to allow putting values in it.</p><p>Such as :</p><p><em><strong>private HashMap<String, Object> locals = new HashMap<String, Object>();</strong></em></p><p><em><strong><br/></strong></em></p><p><em><strong><em><strong>public Object put(String key, Object value) {<br/>     return null;<br/> }</strong></em></strong></em></p><p><em><strong><br/></strong></em></p><p><em><strong>public Object get(Object key) {</strong></em></p><p><em><strong>    if (locals.containsKey((String)key))</strong></em></p><p><em><strong>      return locals.<em><strong>get((String)key);</strong></em></strong></em></p><p><em><strong><em><strong> </strong></em>    else<br/>      return environment.get((String)key);<br/>}</strong></em></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>What do you think about this?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks a lot, Andrew</p></div>
