--------------------------------------
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.
