topic Optional Properties in Task Forms in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/optional-properties-in-task-forms/m-p/25052#M12328 <HTML><HEAD></HEAD><BODY><SPAN>Hi there,</SPAN><BR /><BR /><SPAN>I'd like to have task forms that show properties if they have been defined before, or simply empty values if not. Background is, due to some control flow constructs, some properties may already exist when the task is executed.</SPAN><BR /><BR /><SPAN>Currently, the custom JUEL resolver (org.activiti.engine.impl.juel.RootPropertyResolver#getValue()) throws a </SPAN><EM>PropertyNotFound</EM><SPAN> exception. While this certainly makes sense, I am looking for a way to ask in a form, whether a property exists and if so, make use of its value, e.g.:</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>&lt;textarea name="MyVariable" cols="100" rows="5" &gt;<BR />&nbsp; &lt;c:if test="${exists MyVariable}"&gt;${MyVariable}&lt;/c:if&gt;<BR />&lt;/textarea&gt;<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><SPAN>JUEL documentation didn't give me any help here.</SPAN><BR /><BR /><SPAN>Btw: using … </SPAN><PRE class="language-none line-numbers"><CODE>test="#{MyVariable}"…<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN></CODE></PRE><SPAN> give me a: </SPAN><EM>syntax error at position 327, encountered '#{', expected '${'</EM><SPAN>, </SPAN><BR /><BR /><SPAN>using </SPAN><PRE class="language-none line-numbers"><CODE>&lt;c:when …<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN></CODE></PRE><SPAN> also does not change anything.</SPAN><BR /><BR /><SPAN>Suggestions? Thanks in advance.</SPAN></BODY></HTML> Wed, 10 Nov 2010 11:24:19 GMT mtkunze 2010-11-10T11:24:19Z Optional Properties in Task Forms https://connect.hyland.com/t5/alfresco-archive/optional-properties-in-task-forms/m-p/25052#M12328 Hi there,I'd like to have task forms that show properties if they have been defined before, or simply empty values if not.
