Property Broker

I have downloaded the tutorial for ‘Building a Composite Application’ from the IBM website.

After launching the property broker and entering by properties, I tab to the ‘Action’ tab. The properties I created are not selections in the dropdown for input parameters. It allows me to type them in… but they are not saved.

I have already uninstalled and reinstalled designer in order to get the property broker to open. I am out of ideas.

Karen,

Your problem may be that you didn’t create a Type.

In 8.02 there are two controls under Action Input Parameter. These are Name, a text field, and Property, a combobox. It seems to me that Property should actually be labeled ‘Type’ because this is where you tell the broker the type of your property, not its name.

Unless your property is a primitive type like a String you should create a Type. And that type-name is what you select under Property. It will become available immediately, without saving.

So you should do as follows:

  1. Set up a Type [optional].

  2. Create a Property of the type.

  3. Create an Action to consume that property. Type in the property name and select its type from the list.

To sum up:

Name is where you type the name of your property.

Type is where you select its type.

You were so right ! Adding the type is not part of the tutorial. Thank you for your great explanation.
