Gray Font in UI5 Form Text fields

Hi,

I have developed a SAP UI5 application using non MVC model. The page has a UI5 table, form with levels and text fields. When user select an entry from UI5 table, records get displayed in below form. Normal font color is black when one enters value in text fields but certain time it turns gray font like below image. This behaviour is inconsistent. It appears on multiple double clicks over UI5 table (oTable.attachRowSelectionChange(displayFormData,this);)

Any suggestions please,

SAP UI 5 version - 1.20.6, NW level  7.31 SP 11 PL 7

var oLayout1 = new sap.ui.layout.VerticalLayout( {visible:false,

  content:[new sap.ui.layout.HorizontalLayout( {

  content:[

new sap.ui.commons.Label({text: "{i18n>LBL_TYPE}",required:true,  width:"690px"})
