Factory and methods with parameter in *.wbp-component.xml

[mkornatzki]

My factory has the following constructors:
public static StringValueField createStringValueField() {...}
public static StringValueField createStringValueField(int maxLength) {...}

How should the *.wbp-component.xml look like:
if i use

Code: Select all

   <method name='createStringValueField' factory='true'>
      <name>StringValueField</name>
      <description>Eingabefeld f&#x00FC;r eine Zeichenkette
         <ul>
              <li>value = Objekt vom Typ String</li>
         </ul>
      </description>
   </method>
   
   <method name='createStringValueField(int)' factory='true'>
      <name>StringValueField(maxLength)</name>
      <description>Eingabefeld f&#x00FC;r eine Zeichenkette
         <ul>
              <li>value = Objekt vom Typ String</li>
         </ul>
         Parameter:
         <ul>
            <li>maxLength = Anzahl Zeichen</li>
         </ul>
      </description>
   </method>   

i get the following error:

Code: Select all

In the export of the palette the methodname is name="createStringValueField()"
if i add brackets in the xml-file like <method name='createStringValueField()' factory='true'> instead of <method name='createStringValueField' factory='true'>
i get the same error.

Give this a try using the latest build.

Now i didn't get an error on the consoleLog but if i use brackets in the xml even whithout adding the component for the definition then the whole category is collapsed and can not get opened.

Then i tried to add the component but the "add static factory" dialog show that my factory class has no factory methods (but it has).

Sorry, i make a mistake in the subject. It should be "wbp-factory" instead of "wbp-component".

The problem for me still exists.
How do i define factory methods with parameter in the xml-file?

michael
