Text area in service order UI component not taking more than 255 characters

Hello Friends,

We have a custom UI service order component that is built on ISUSERVICEORDER. We created a text area for LONG_TEXT which is saved into the service order notes in ECC.

We are unable to save more than 255 characters in the text area. LONG_TEXT field in CRM_ISU_SRV_ORDER_CREATE is of 300 characters.

Also I tried adding a new custom field to this structure for 1250 characters and created a text area  on the UI screen for this field. It still did not let me save more than 255 characters.

Looking forward to your inputs.

Thanks!
