• to configure the clientside maxLength param for input fields in html, add the maxCharacter attribute to the controls-section of the specified element in the config json

  {
              "id" : "comment1",
              "label" : "Kommentar 1 (40 Zeichen)",
              "maxCharacter" : 40,
              "type" : "textarea",
              "size" : 5,
              "pageElementsLink" : {
                  "kommentar1" : "value"
              }
  } 
  

• line breaks in class mbParagraphDecorator will be added if the defined width in the width attribute in the pages->elements section of the specified element in the config json is reached for the pdf cell

  "kommentar1" : {
                      "type" : "para",
                      "x_ul" : 39,
                      "y_ul" : 269.8,
                      "font_family" : "Arial",

                      "width" : 100,
                      "height" : 5,
                      "align" : "L",
                      "border" : 0,
