Subject RE: OGNL Exception after upgrading from 2.3.4 to 2.3.14
Date Wed, 08 May 2013 16:20:44 GMT
I should note that the setItems() method and List<String> variable are on the model object
exposed by the ModelDriven<> interface.

Subject: OGNL Exception after upgrading from 2.3.4 to 2.3.14

We have several forms in our Struts2 application that pass values to the action like the following:

  <s:textfield name="items[0]" size="30" maxlength="100" />
  <s:textfield name="items[1]" size="30" maxlength="100" />
  <s:textfield name="items[2]" size='30" maxlength="100" />

This worked beautifully prior to the upgrade but now I get the following OGNL exception:

Unexpected Exception caught setting 'items[0]' on 'class com.setech.dw.inventory.web.ItemSearchAction:

The action doesn't allocate memory for the List<String> property and never has.
Is there something I may have missed that I need to change from upgrading from 2.3.4 to 2.3.14?

Thanks,
Chris
