Fill textbox default with java

[Markus Axelsson]

This will probably my last question about this plugin.

I have what seems as a simple issue. I want to give a default value to a textbox in my PlotBuilder\config.jelly:

<?jelly escape-by-default='true'?>
<j:jelly xmlns:j="jelly:core" xmlns:st="jelly:stapler" xmlns:d="jelly:define" xmlns:l="/lib/layout" xmlns:t="/lib/hudson" xmlns:f="/lib/form">
  <f:entry>
    <table width="100%">

...

      <f:entry title="${%CSV filename *}" field="csvFileName" help="/plugin/plot-pipeline/help-csvfile.html">
        <f:textbox name="csvFileName" value="${plot.csvFileName}" clazz="required" default="${it.csvFileName}"/>
      </f:entry>

...

    </table>
  </f:entry>
</j:jelly>

See complete file here.

My PlotBuilder.java contains the following method:

public String getCsvFileName() {
    return "plot-" + String.valueOf( (int)Math.round( Math.random() * 100000000 ) ) + ".csv";
}

See complete file here.

This resulted in nothing, the textbox in completely empty. 

I was able to do this in different jelly with a different java but not here. The other java implemented Action and StaplerProxy, and for the sake of it I tried to implement those in my PlotBuilder.java as well but without success.

The it reference is probably not referring to what you think it is, or probably null in case you are adding a new step (there is no instance of the step yet). So you probably need to add your helper method to the descriptor instead.

Thus `default="${descriptor.defaultCsvFileName}"` where
`DescriptorImpl` contains `public String getDefaultCsvFileName()`.

Great! Moving it into the 'DescriptorImp' sure did the trick!
