Dynamic Table and Templates

[messmeister]

Hello,

i have a question about the "Generate Document Task" in Alfresco Activiti Suite 1.4:
is there any info on how to list entries of a dynamic table with a MS Word template? <<[myTable]>> is printing the contents of the table as a json string and i cannot use <<foreach [in myTable]>> to iterate of the table entries.
The dynamic table was created with the default Form Editor.


Thank you for any information on this!

It seems i cannot use the LINQ expressions in this forum because it get's escaped with < >.
I wanted to say that i cannot use the foreach expression with the dynamic table.

Hmm, i think you will need to do some pre-processing on the dynamic table json before it's passed into the template:

see https://docs.alfresco.com/activiti/docs/dev-guide/1.4.0/#templateVariableProcessor
(it's a bit crude, as it's applicable to all templates, but it'll get the job done. We will add a more refined mechanism in the future)

Thank you very much for the info! Do I have to invoke my custom processor in the template? Because if I follow the example in the developer guide as you mentioned, nothing happens.

You have to put a class implementing that interface on the classpath. Make sure it's
1) in the right package (com.activiti.extension.bean)
2) has @Component on it

If you had that already … please share your code here

Hi, i've double checked and yes, it is the correct package and it has the @Component annotation.
<java>
package com.activiti.extension.bean;

import com.activiti.api.docgen.TemplateVariableProcessor;
import org.activiti.engine.delegate.DelegateExecution;
import org.springframework.stereotype.Component;

import org.apache.log4j.Logger;


@Component
public class CustomTemplateProcessor implements TemplateVariableProcessor {

    private static final Logger logger = Logger.getLogger(CustomTemplateProcessor.class);
    public Object process(DelegateExecution execution, String variableName, Object value) {

        logger.info("processing….");
        return value.toString() + "___" + "HELLO_WORLD";
    }
}

</java>

It's not doing anything at all.
FYI: I have other beans in the same package to use as script task expressions and they are working just fine…
Any idea??

Thank you very much!

Hmm that looks allright. I tested it a few weeks ago and it worked. I'll recheck tomorrow and post back here.

[messmeister]

Thank you very much! I'm looking forward to your response.

For a custom TemplateVariableProcessor to be called the variable should be in the following format in the template
<<[variables.get("varName")]>>

Hi Team,

I have a same requirement.

Could you please tell how you implement it.What we need to process in Custom Template Processor.

Thanks
