             Summary: Form widget: the image element used in the field element does not work when used with an existing field value
                 Key: OFBIZ-9200
                 URL: https://issues.apache.org/jira/browse/OFBIZ-9200
             Project: OFBiz
          Issue Type: Bug
          Components: framework
    Affects Versions: Release Branch 16.11, Release Branch 15.12, Trunk, Release Branch 14.12, Release Branch 13.07
            Reporter: Jacques Le Roux


When you use the image element with a field name of an existing field value a fake chained request is weirdly called. This is true in both simple and list/grid forms, I did not test multi but I guess it's the same.

For example if you add this line
bq.        <field name="exampleName"><image value="/images/defaultImage.jpg"/></field>
just after the line
bq.        <field name="exampleName" title="${uiLabelMap.CommonName}" sort-field="true"><display/></field>
in the ListExamples form you get as much as errors as there are examples, eg:

As you can see from the stack trace it's a tricky bug

A workaround is to use a non existing value as field name when you can, for instance combined with an use-when. But of course this is not satisfactory and you also can't use entry-name to bypass the issue.
