Known issues

  • Issue: When you configure any of the JDBC datasources (e.g., MySQL, Oracle, etc), the driver is not added. (STUDIO-1217)
    Workaround: Add the driver manually by right-clicking on project root > Build Path > Add External Libraries > Browse , then adding the corresponding . jar file.

  • Issue: For certain JDBC datasources, Mule requires that 'user' and 'password' not be configured in the URL; instead, they must be specified through separate attributes. Although these attributes are not required, and technically, at least, the credentials can be configured through the URL, you must, in any case, set them through attributes.
    Workaround: If you have a blank password, you must go to the XML view and edit the password attribute so that password="".

  • Issue: The payload cannot be passed as an argument to Salesforce upsert, insert, etc. (STUDIO-1221).
    Workaround:Go to the XML configuration file and add the payload reference as follows:

    <sfdc:upsert type="Account" externalIdFieldName="InternalAccountCode" doc:name="Salesforce">
                    <sfdc:object ref="#[payload]"/>
  • Issue: When dragging a Connector message source (i.e., Salesforce (Streaming) or Twitter (Streaming)) from the Palette and dropping it onto the canvas, an error announces that the flow should start with an inbound endpoint. (STUDIO-1224)
    Workaround: Disregard the error, since the Connector message source is, in fact , an inbound endpoint.

  • Issue: Neither the HTTP nor HTTPS Polling Connectors can be referenced using the Properties pane in the Message Flow view. (STUDIO-1077)
    Workaround: You need to make the reference using the XML configuration view by adding this: ref="HTTP_Polling"

  • Issue: When you remove a Request-Response endpoint or replace it with a One-Way endpoint in the Message Flow view, the response element is not removed from the XML configuration file. (STUDIO-866)
    Workaround: Delete the Response element manually from the configuration file using the XML editor.

  • Issue: When you add the schema namespace and location manually using the XML configuration view, then switch to the Message Flow view to continue working, those two elements are not persisted. (STUDIO-487)
    Workaround: Try to use the graphical mode. However, when you encounter an element that you want to use but is not there, go to the configuration XML view and add it manually. Try to do this when all your flows are almost complete, and you no longer need to use the graphical editor. Make sure that you save the project frequently.

  • Issue: Unable to add a response element when creating a second flow within a single mflow file. (STUDIO-459)
    Workaround: Add the response element manually in the XML configuration.

  • Issue: For request-response endpoints embedded in a composite source within a subflow, icons do not show the proper exchange pattern.
    Workaround: This is only a matter of visual aesthetics within the graphical interface; if you set the correct exchange pattern through the Properties pane, the flow should work as intended, despite appearances on the Message Flow canvas.

  • Issue: The Description field is not persisted when you switch back and forth between the Message Flow and XML configuration views. This issue may appear in the bundled examples that are included in Mule Studio. (STUDIO-162). Currently, there is no way to populate the Description field using the graphical interface.
    Workaround: Once your application is complete and you are sure that you don’t need to use the Message Flow view any more, copy the description and insert it into the configuration file using the XML editor.

  • Issue: When you create a project from an existing template, the Problems pane may display errors such as the following:
    "Unable to find type 'org.ordermgmt.OrdersView' on build path of project order_f
    Workaround: From the main menu, navigate to \{\{Project > Clean…​ }}, then select clean all projects. This re-compiles all your projects, so that these errors no longer appear.

  • Issue: When you install the Windows 64-bit version of Mule Studio with the IBM JDK, then create a project using the Order Discounter template, the Problems pane may display errors such as the following:
    "Attribute key is not defined as a valid property of object Element:Objects is not allowed to be child of element Object"
    Workaround: Ignore the errors and run your application. It will run successfully.
