Working With the Message Contents Panel

Toolbar

You work with the message data using the toolbar items:

Item	Description
View Body as Text	Displays the message contents as text (if possible). Click this item again to return back to the non-text view mode.
Save Data to File	Saves the message contents to a file. To extract message data to a variable, create a data selector.
Load Data From File	Replaces the message contents with the data from a file. For the Server Message operation, this means that you change the expected server response. For the Client Message operation, this means that you change the data to be sent to the server. An alternative way to change message contents is to create a data replacer.
Clear All Body Data	Removes the body data. For the Server Message operation, this means that you change the expected server response. For the Client Message operation, this means that you change the data to be sent to the server.
Encoding	Select a character encoding to display the message content. The following encodings are supported: UTF-8 ANSI Available if the message is displayed as text.
Word Wrap	Enables or disables word wrapping in the panel. Available if the message is displayed as text.

Server Message Actions

To ...	Do this ...
To retrieve data from the message body	Create a data selector in the Data Selectors panel (by default, it is at the bottom of the operation editor, next to the Message Contents panel). Data selector will save the data to a variable. If you need to save data to a file, click Save Data to File on the toolbar.
To verify the data of the received message	Create a data selector to extract this data from the message body and then create a validation rule in the Validators panel (by default, it is at the bottom of the operation editor like the Message Contents panel).

Client Message Actions

To ...	Do this ...
To change message contents before simulating a request	Create a data replacement rule in the Data Replacers panel (by default, it is the next tab in the operation editor). Using a data replacer, you can change part of the message content or the entire content. An alternative approach to change the entire content is to load it from a file. To do this, click Load Data From File on the toolbar.

No Data to Display

The panel shows the "No data to display" message if the appropriate message does not contain any data. For example, this can happen if it is the Close message.

Content Size Limit

If the message content is large and showing it may cause performance issues, the panel will not show it by default. It will show a message informing you about possible issues. You can click Show anyway to view the content.

If the message content exceeds the following limits, the panel will not show the content at all:

For 32-bit operating systems: 25 MB.
For 64-bit operating systems: 100 MB.
