topic Can't evaluate boolean expression in usertask in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/can-t-evaluate-boolean-expression-in-usertask/m-p/144246#M100883 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>as the topic says, I get a warning when completing a usertask. My process: User A starts it and some variables are created and some task are done. A parallel gateway leads to eventbased gateway and a usertask of different lane. One event is a timer the other a signal. After User B fulfills that usertask a signal is thrown and User A can continue. The variable "buyArticle" is type of boolean and the userform property type is the same. If I finish that task I get: Warning –&gt; "Error while evaluation boolean expression: #{buyArticle}"</SPAN><BR /><BR /><SPAN>I evaluated strings and longs inusertaks (User A) before without problem. Is there a problem because variables are defined in lane 1 and this usertask is lane2 (but in scripttask(lane2) the variable is recognized correctly[defined with execution.setVariable("buyArticle,true")]).</SPAN><BR /><BR /><SPAN>I have no idea whats wrong with this expression. I hope someone can help me with this issue.</SPAN><BR /><BR /><SPAN>With kind regards,</SPAN><BR /><BR /><SPAN>FellowTom</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE><BR />&lt;userTask id="usertask4" name="check article and do purchase decision" activiti:assignee="kermit" activiti:candidateUsers="kermit"&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
