Issue 31083 — HTML5 controls : DSP widget loses focus after onChange trigger is fired
Status: Solved in 10.2.01
Solution available in patch(es): G101
There is no known workaround for this problem.
When a trigger or operation is called, fields that are in scope are not disabled any more, since this would prevent them from receiving focus; instead, they are set to read-only for the duration of the request. Additionally, elements are not destroyed and re-created if no changes were made to a field's valrep, since this would effectively remove focus from the elements that were destroyed.
