XML Application Using Custom Code Fails to Process

jbucher

I have attempted to include a custom method execution statement in an XML application and am receiving a string index out of range error. I have narrowed the issue down to passing an element variable as an argument to the method. So based on the XML Application documentation, I thought I had determined this to be legal:

1. Declare appropriate java class(es) in XML application.

2. Declare a variable to capture the specific XML element I need to analyze in the custom method

3. Pass the variable defined in 2 to the method in 1 (receive in the method as a string)

4. Process the XML string

5. Return a string value (to be stored into a dctm_attr) as a string

So the behavior I'm seeing is that I'm able to pass a string to my custom method, however when I try to pass the element variable the following stack trace is provided in the log and from the client:

The syntax I've used to include the variable reference in my XML application config file is:

<dctmattr_repeating>
    <name>sys_attr_name</name>
    <template><expression>myMethod:getStr(<var name="myVar"/>)</expression></template>
</dctmattr_repeating>

Does anyone have a suggestion for where I may be going wrong? Thanks.

Seems like your XML is not well formed

<dctmattr_repeating>
    <name>sys_attr_name</name>
    <template><expression>myMethod:getStr(<var name="myVar"/>)</expression></template>
</dctmattr_repeating>

Basically, if you format your XML, that wold give something like

<dctmattr_repeating>
    <name>sys_attr_name</name>
    <template>

          <expression>myMethod:getStr(

               <var name="myVar"/>

               )

          </expression>

     </template>
</dctmattr_repeating>

As you can see, the Documentum XML parsers would think that <var name="myVar"/> is a node in the XML structure, which, I assume it is not

Validate the XML in your XML editor to see what it says and what it suggests
