Re: Complex expressions don't execute in Alfresco activiti web version

The error clearly states what is wrong with the expression. You have a = instead of a == in the condition. Now, it looks like your problem might be related to the fact that you are writing the expression in BPMN XML with some kind of tool which does not automatically encode < and > correctly, so they are dropped / lost when the XML is parsed. Try using &gt; and &lt; in XML, or enclose your conditions in CDATA blocks to avoid issues with reserved characters.
