error CE1571: No argument has been selected for parameter PageInfo and no default is available. with Nanoflow

0
hello,  I am configuring a simple Nanoflow as follows: However, I encountered the error CE1571: 'No argument has been selected for parameter "PageInfo" and no default is available.' In the JavaScript action the current page name will be extracted.   PageInfo is a Non-persistable Entity with an attribute currentPageName of type String. In the Nanoflow, the page name returned from the JavaScript action is assigned to an instance of the PageInfo entity.     The Decision evaluates the currentPageName attribute of the PageInfo object to check if it is equal to a specific page name. If true, the form will be populated automatically. Could someone show me my mistake? Thank you in advance.

Hi Yuan , 

Do you need the PageInfo entity as a parameter to this nanoflow? Are you using this parameter. If not remove it. Error will be resolved.

there is a list on the page. If I click the box "Abteilung", iA Nanoflow would be called, and fill this box automatically based on the condition in decision in Nanofow. 8.png

Thank you Stella, in this page there is only object Themen_extn (in green circle). I should add also pageInfo,? Should I use an association here, am I right?
